How to Practice the Giant Steps Cycle: Video Tutorial and Supplementary Material

My preoccupation with John Coltrane’s tune “Giant Steps” now ebbs, now flows, but always continues. I’m not the most fabulous alto sax man who has ever played the changes, certainly not in the league of Kenny Garrett, but I have my own approach, which I strive to make less digital and more lyrical. I’ve even had the temerity to write a book of licks and patterns on “Giant Steps” titled The Giant Steps Scratch Pad, available for instruments of every key.

In the following video tutorial, I share a couple approaches to practicing the Giant Steps cycle that I have found profitable in my own practice sessions. The video begins with a bit of theory; however, the theory behind “Giant Steps” is more than adequately covered elsewhere in greater depth, as in this excellent article by Dan Adler, and it isn’t the thrust of the tutorial. Rather, I address a more pragmatic concern: How do you wrap your fingers around the Giant Steps cycle? The tips I share in the tutorial certainly aren’t the only way you can or should tackle the cycle, but I think you’ll find them helpful. Briefly, I explain how to run both a one-bar pattern and a more extensive two-bar lick through the cycle.

The two patterns used in the video were taken from The Giant Steps Scratch Pad. For your convenience, I’m supplying them for you here. Note that these excerpts are from the Eb edition, suitable for alto and baritone saxophonists; if you play a C, Bb, or bass clef instrument, you’ll need to transpose (though editions of my book are available in your key).

And now, here is the video. It’s obviously a homespun effort, so please bear with its flaws. I haven’t figured out how to read from my PowerPoint notes and still look directly at the camera, and as for that stupid deer fly that lands on my forehead while I’m signing off and roams around like an astronaut exploring the lunar surface, I wasn’t aware of it till I got home and viewed the clip. You think I’m going to do a redo just for that? It’s part of filming outdoors: mosquitoes setting up drilling operations on my nice, pink flesh, deer flies exploring my noggin—I deal with it and you can too.

Go ahead and chuckle. But if you’re a jazz improviser who’s tackling “Giant Steps,” then I think you’ll nevertheless find this tutorial worth your while.

 

Book Review: The Scale Omnibus by Francesco Balena

Francesco Balena operates the website Saxopedia, a tremendous resource for saxophonists and jazz musicians of every stripe. If you play the sax—or, for that matter, any instrument—and you are not familiar with Franco’s site, then I highly recommend that once you have finished reading this post, you go directly to Saxopedia and acquaint yourself with it. The exhaustive collection of links to solo transcriptions alone is enough to place Saxopedia in the upper echelon of saxophone resources. But there’s much more besides, and that now includes Francesco’s new masterpiece, The Scale Omnibus: 392 Scales for Instrumentalists, Composers, Vocalists, and Improvisers. The amount of material covered in this 429-page, downloadable book is simply staggering. And it’s free.

Did you get that? Free. In the author’s words, “The primary objective of this book is making in-depth knowledge about scales available to the largest number of people as possible. For this reason The Scale Omnibus is free. Free as a free lunch. No strings attached.” There are a few commonsense stipulations in the use of the material, but the bottom line is that Francesco, in keeping with the spirit of Saxopedia, has created what has got to be the most comprehensive repository of scales ever assembled, and now he is making it available to musicians at no cost whatsoever.

It’s a fantastic accomplishment on Francesco’s part, the fruit of considerable time, research, insight, and plain, solid labor; and it is an equally remarkable gift to jazz musicians in search of fresh ideas for improvisation.

Organization

The Scale Omnibus is well-organized and easy to use. Following a thoughtfully written, insightful introduction, the book plunges directly into the material, beginning with the common major and minor scales and their modes and then progressing, per the table of contents, through

  • Symmetrical Scales
  • Jazz Scales
  • Pentatonic Scales
  • Modal Scales
  • European Scales
  • Asian Scales
  • Indian Scales
  • Miscellaneous Scales

Every scale is allotted its own separate, full page. Scales are presented in ascending form in all twelve keys—with the exception, for obvious reasons, of the chromatic scale—and in descending form as well for a few of the Indian ragas whose ascending and descending forms differ. Each scale is preceded by brief, helpful notes that cover its alternate names, modes, construction, harmonic applications (i.e., which chords it works well with), and in some cases, its country of origin.

Following the presentation of the scales themselves, the book includes four appendices that provide a scale index and scales by name, interval, and chord. The last appendix, Scales by Chord, strikes me as particularly useful, providing a quick match-up of chords with scale options. Many of the options will be familiar to experienced improvisers, but there are surprises. For instance, until a short while ago, I had no idea that the Romanian scale could be used with a minor seventh chord. (For that matter, I had no idea there was such a thing as a Romanian scale.) This particular appendix is by no means exhaustive, given the vast array of possibilities covered by the book, and Franco might consider expanding the list of scale choices in a future edition. However, the amount of time required to do so would no doubt be considerable, and the appendix as it stands is an eminently useful tool, furnishing a greater selection than similar lists such as Jamey Aebersold’s chord/scale syllabus.

About the Scales

The Scales Omnibus gives all scales, both the everyday and the exotic, equal coverage. But while it begins with the major and minor scales all Westerners relate to, whether trained musicians or everyday listeners, it goes far beyond those scales into territory most of us aren’t familiar with. For instance, turning to the first page of the section on Asian scales, I come across something called the Honkoshi scale, which, I am informed, originated in Japan; generates, as its modes, the Raga Hamsa Vinodini, the Raga Manavi, and the Insen scale; and works well with a half-diminished chord. Following it is the Ichikotsucho scale, also known as—are you ready?—the Major-Lydian Mixed, Gregorian 5, Genus Diatonicum Veterum Correctum, Kubilai, Raga Bihag, Raga Gaud Sarang, Raga Hamir Kalyani, Raga Kedar, Raga Yaman Kalyan, and Raga Chayanat. Stick that in your horn and play it (preferably over a Cmaj7 or Cma7#11).

Does this book cover every possible scale under the sun? No. Francesco has screened out scales of fewer than five notes; such scales exist, but when tones become so sparse, the use of the term scale becomes questionable. Also, significantly, the book covers only scales that fit easily within the twelve-tone, well-tempered system. Francesco writes, “Microtonal scales, scales that use just temperament, and scales that use equal temperament obtained by dividing the octave in a different number of intervals—as is the case of some Arabian scales—are not included.”

In Summary

A book so vast in its scope as this can only provide the basic scales and insights on their use. From there, it’s up to you to determine which scales interest you most and develop exercises that will help you master them. No way will you or anyone ever internalize all of them. But even one new scale is a tremendous acquisition for the improvising musician, and to that end, The Scale Omnibus is a treasure trove of possibilities. Franceso could easily ask $25.00 or more for this volume; instead, he’s offering it for free, and in so doing, he has added even more value to an already immensely valuable website for jazz instrumentalists, particularly saxophonists.

A work of such excellence and heart as Francesco’s book, given so generously to others, deserves support, and it is in that spirit that I have written this unpaid and unsolicited review.

Bravissimo, Francesco! You’ve given a gift to musicians everywhere. Thank you.

Rhythm Changes: An Etude to Build Jazz Technique

rhythm changes, jazz improvisation, jazz etude 001Here’s a little bop-style etude I created to help build your chops for rhythm changes. No surprises here; I wasn’t striving for cutting-edge ideas but for simple building blocks of jazz vocabulary. Me being an alto sax guy, I’ve written the material in the key of G, which is the alto transposition for the standard “Rhythm” key of Bb. Tenor players, flute players, and so on–sorry for the inconvenience, but you know how to transpose, right? Or just play it as written and hone your facility with the key of G. Click on the image to enlarge it and then have at it. And have fun!

I’ve written in the past about my predilection for rhythm changes as a means of developing a fundamental jazz vocabulary. In their essence, the changes can be construed as simply a succession of turnarounds with a bridge based on the cycle of dominants. You can get as fancy with that as you want to, but the basics are just as simple as the word basic implies.

For more on rhythm changes, click here. I also encourage you to read the point-counterpoint between Kurt Ellenberger and me which evolved out of that post. Whether you love rhythm changes or, like Kurt, hate them, you’ll find food for thought.

If you enjoyed this post, click here for plenty more articles, exercises, and solo transcriptions. Also, a quick plug for my book The Giant Steps Scratch Pad. If you’d like a practical, hands-on practice companion to help you master “Giant Steps,” well…that’s why I wrote it.

How a Late-Season Storm Chase Nearly Ended in Tragedy

With this year’s severe weather season ramping up–as I write, Missouri and Arkansas are primed for supercells and tornadoes later today–I want to share the following with my fellow storm chasers. Many of you are people I know and care about, and some of you are quite close to me. I know some of the risks you take because I take them myself; we all do, to varying degrees. To my thinking, tornadoes are usually at the lower end of the risk spectrum. At the top is what happens on the road. That’s something over which we have considerable control, and with it, a responsibility for our own safety and the safety of others.

In a heartbeat, an exciting chase can turn into a second or two of horrified disbelief followed instantly by noise, violence, injury, and perhaps death. I know because I’ve lived it, and I hope no one else I know ever has to. That’s why I’m sharing the following account, written last December. Perhaps it’ll inspire you to exercise greater care and awareness on the road. Please take it to heart. I’d like it to be a long time before the next set of initials gets outlined on the radar by Spotter Network icons—and when that day does arrive, I don’t want those initials to be yours.

Saturday, December 7, 2013.

A short while ago, I was lying on my side on the living room couch, giving Lisa’s cat a full-body rubdown and listening to her purr. Siam is one of the sweetest, best-behaved little creatures you could hope for, affectionate and enormously tactile. Being held and petted are things she takes for granted as her natural due, and she gets plenty of such treatment. So there was nothing remarkable that I should be stroking her soft, cream-and-chocolate fur.

And yet, there was everything remarkable about it. When you’ve nearly had your life suddenly snuffed out just before the holidays, the most commonplace act can strike you as extraordinary.

The fact that I am still here to pet this vibrant, blissfully thrumming little motor . . . that I am here to see Lisa smile, and to hear her laugh, and to look into her sparkling eyes as I hold her in my arms . . . that I am here to tell my dear eighty-eight-year-old mother and my sister, Diane, that I love them, and to share more beers with my friends, and to turn the ignition switch in my “new” used Toyota Camry which, as of yesterday evening, has replaced the one I lost three weeks ago . . . these things are remarkable. Never fool yourself into thinking that the simple and the everyday are anything less than a gift and a miracle.

Things could have turned out very differently. By now, my body could have been lowered into the cold earth, leaving my loved ones to face this Christmas with broken hearts instead of warmth and gladness. Instead, I am still here and blessed with,  surrounded by, reminders that the simple act of petting the cat, or lifting this mug of hot chocolate that Lisa whipped up for me a little while ago, or watching downy snowflakes dance in the air beyond my balcony slider, or even feeling the diminishing but still-present pain of a cracked sternum, is an extraordinary thing.

The Setup

On November 17, I was chasing storms in eastern Illinois and western Indiana with my friends Tom Oosterbaan, Rob Forry, and Shawn Kellogg. The occasion was an unusual late-season setup featuring a vigorous, negatively tilted trough digging into the Midwest. On its eastern side, a surface low was pulling in moisture-laden southerly winds from the Gulf of Mexico as it tracked northeast through the Great Lakes.

SPC Day 1 Convective Outlook, 13Z, November 17, 2013

SPC Day 1 Convective Outlook, 13Z, November 17, 2013

For a good week, I had been following the forecast models with both skepticism and growing excitement as they progressed from the meager CAPE one expects this time of year to unseasonably high instability, mid-60s dewpoints, and some truly rabid wind shear. On November 16, the Storm Prediction Center issued a moderate risk for its day 2 convective outlook, then upgraded it to a high risk on the morning of the 17th. The ingredients were falling into place for the kind of high-shear/low-CAPE tornado outbreak that is typical of the Great Lakes. It would culminate in the deadliest, most violent November outbreak on record.

The setup bore some disturbing similarities to the notorious April 11, 1965, Palm Sunday Outbreak. And it wasn’t happening in Oklahoma or Texas. For a change, it was all coming together in my backyard, so to speak. Chasers from all over the map had converged on Illinois and Indiana–hardly the heart of Tornado Alley, but the most chaseable terrain in the world when it does produce.

Although Rob was willing to drive his Jeep, I volunteered my 2002 Camry. I had acquired it last February, and it was in great shape and was a comfortable ride. At last I had a roadworthy vehicle, and having benefited so often from other chasers driving their vehicles, I was pleased to be able to provide the transportation for a change.

We left Grand Rapids around 8:00 a.m. and met briefly for breakfast with Bill Oosterbaan and Kim Howell down at Kim’s house in Niles. Kim had prepared a generous spread for us (Kim, you’re the swellest!), but we were in a rush and had to just wolf it down, then Rain-X our windshields and hit the road. We did, however, make time to do one last thing before we took off. Joining hands, all six of us prayed, asking the Lord’s protection for us and for those in the areas that would be impacted by the storms. I believe that prayer was providential. None of us in my vehicle had an inkling of what lay in store for us a few hours later.

The Chase

Our target was northwest Indiana around Rensselaer, where the 500 mb jet max looked to nose in over substantial low-level instability. With storm motions forecast at 60 knots (see NAMM hodograph–click to enlarge), the storms would be rocketships, and it seemed that our best bet would be to set up east of them, watch the radar, and then jockey into position and hope for the best.

I wish we had stuck with that plan. But the big, discrete supercell which proved to be the day’s main player showed strong, persistent circulation, dropping a string of strong to violent tornadoes–including the deadly Washington, Illinois, EF-4– on its journey northeast from Peoria toward Chicago. Bill and Kim decided to go for that one and wound up intercepting a rain-wrapped tornado.

On our part, the storm looked mighty tempting, but we chose to let it go, not wanting to chase it in urban territory. That left us with the other storms which were approaching from the southwest, and we made the mistake of heading out to meet them rather than letting them come to us. It was a defensible decision: the storms were beginning to congeal into a line, and we wanted to catch them while they were still reasonably discrete. As it turned out, we’d have done fine had we simply exercised patience. But instead, we headed west into Illinois, then dropped south and ultimately wound up backpedaling east back across the border to intercept an HP supercell that was showing rotation on the radar.

At this point, I need to mention that Rob was driving and I was sitting in the front passenger seat with my laptop on my lap, monitoring the radar and navigating. I’ve mentioned that Illinois and Indiana easily comprise some of the best chase territory anywhere. Their flat, wide-open stretches of agricultural land let you see for miles, and their regular grids of paved country roads make for easy driving. Even the wet gravel roads are generally far easier going than the slippery gumbo out west. You just can’t ask for a better road network or better topography.

Southwest of the town of Oxford, Indiana, our storm appeared to crap out on us on the radar. The echo weakened, and while the storm just to the southwest was tornado-warned, the base reflectivity suggested a comma-head on a small bow echo, not a supercell. That was the last radar scan we got before we lost Internet connection. And storms can reorganize rapidly, and–well, ours did. Shortly after, an inflow jet shot across the road in front of us from the south and then rapidly enveloped us. What the . . . ? Rob rolled down the window, and we could hear a roar to the north. What was causing it? An updraft region had to be over there. But it was wrapped in precipitation, and telltale storm features were utterly lacking. Yet logic told me that somewhere within that bland-looking sky, a mesocyclone was buried, possibly even a tornado. At the very least, some kind of high-wind event had to be taking place nearby.

Not only so, but a dark shadow was moving along to our south, heading tangentially in front of us. Tornado? Just a darker cloud in that unremarkable sky? Impossible to tell. I shot some video, hoping that the camera would reveal features that my naked eye couldn’t discern, but there was no such luck. All it gave me was my sole record of our chase that day.

A look at the reflectivity on Rob’s cell phone app a couple minutes later revealed that our storm, which had appeared weak and disorganized in the previous scan, had in fact morphed into an embedded supercell. We had been on the southern end of the hook.

As we headed into Oxford, we began to see signs of significant wind damage–nothing tornadic, just straight-line, but still a handful for the residents of that town to have to clean up.

We were losing our storm, and once we were on the other side of Oxford, Rob picked up the pace. By then, though, I think our chase was effectively over. The storms were beyond us and moving too fast for us to catch up.

The Crash

Not quite two miles east of Oxford, the road we were on, eastbound SR 352, intersects northbound US 52. We were travelling at a good clip–too fast for conditions, as I think Rob will agree.

Ahead of us lay a hillock where a railroad track crossed the road. It was a blind rise that blocked our view of the other side. Rob slowed down for the tracks, but we were still probably doing 40 mph when we crested them and got our first glimpse of what lay beyond. To our horror, a stop sign and a divided highway were situated downslope no more than 200 feet away and probably closer. And to make matters worse, a vehicle was pulling out of a service road on the right into our lane. Rob swerved and braked instantly, but the pavement was wet, we were heading downhill, my nearly new all-weather tires failed to grab, and we skidded into and across the southbound lane on a collision course with a northbound van.

I remember watching the grill of the other vehicle looming toward me. The next instant, there was a bang, and our vehicle careened across the rest of the lane and came to a stop on the far side of the highway. I don’t remember the airbags deploying, but they did, and no doubt they saved Rob and me from serious injury.

For a second, the four of us sat there, stunned. Then we piled out of the vehicle. As I stood up, I could tell that something was wrong with my chest. While I don’t recall its happening, presumably the airbag had driven my laptop into my ribcage. At the moment, I was experiencing only discomfort, but I knew that I had been injured, and it was only a matter of time before the pain would set in. In that expectation, I was not disappointed.

My Camry after the Crash

My Camry after the Crash

The point of impact for the two vehicles had been headlight-to-headlight at right angles, my Camry’s right headlight connecting with the van’s left headlight.

I won’t go into all the details from here. I will just say that we and the people in the van were very, very blessed. God preserved us, sparing us any real harm, and Shawn pointed out that the prayer we had prayed before we left had been no mistake. What went wrong was obvious, but there was also much that went right, more than we had any reason to expect. It was amazing that we had made it unscathed across the southbound lane in the first place. And the angle of collision couldn’t have been more merciful. Just a second faster or slower for either vehicle would have resulted in a T-bone and almost certainly in serious injuries or fatalities. It was a busy highway; had a semi been coming . . . I don’t even want to think of it.

Huge thanks to fellow chaser Eric Treece, who gave Shawn, Rob, and me a ride back up to I-94, where Rob’s wife picked us up; to Bill Oosterbaan, who came to help and to retrieve his brother, Tom; and to Holly Forry for dropping what she was doing in order to make the long trip out and then drive her husband, Shawn, and me all back to my apartment.

Above all, thank you, Father, for sparing us. Thank you for protecting the innocents in that other vehicle, and thank you for protecting us. Thank you that this Thanksgiving, we have all had much to be thankful for, and that this Christmas, we all will celebrate the birth of your Son, Jesus, once again with our families, as we have done for so many years and hopefully will do for many more.

Accident Corner

About the intersection where our accident occurred: If you go there, you will see that the setup is an accident waiting to happen, and many accidents have in fact occurred there. At least, that is what we were told by both the sheriff and one of the ambulance drivers. I don’t recall seeing a “Stop Ahead” sign, and the other guys maintain there was no warning. Logic tells me that surely there had to have been one, but all I remember seeing was a yellow RR crossing sign as we approached the tracks. That was it.

The tracks were at the top of a rise, and only upon crossing them do you see the stop sign, the side road, and the highway down below. The proximity of the intersection to the tracks comes as a shock (unless, of course, you live in the area), and you’ve got little room to respond. In other words, it’s a horrible setup that is perfectly engineered to catch motorists off-guard. It’s lethal in wet weather and has got to be a terror in the winter. According to one of the guys, the sheriff had mentioned that his department had been after the county to improve the intersection because of the danger it posed, but so far the county had done nothing about it.

So I can’t be too hard on us. But I can’t be too easy, either. We were going too fast for conditions, and I wish I had told Rob to go slower. I’m so glad we all came out of it okay. Banged up and hurting, definitely, but  no one in our vehicle or the other one sustained serious injuries or went away in an ambulance. I thank God, most sincerely, that all of us experienced the very best possible outcome of a very bad scenario.

A Word to the Wise (and the Not-So-Wise)

Now, here is what I want to say to all of my fellow chasers: It could have been worse, and it could have been you.

Watch your driving.

My main fear in storm chasing has never been the storms. It has been hydroplaning or otherwise losing control of the vehicle on wet pavement. It is the thing that happens to people who think it won’t happen to them.

I consider myself a cautious driver. Next to some of you, I come across as the little old guy wearing the brown suit and hat who putters along at 45 miles an hour down the Interstate. However, most of the time, I’ve been a passenger, not the one who has driven on chases, and over the years, I have witnessed driving habits that frankly have scared the crap out of me: Chasers rocketing along at 80 miles an hour down wet, curvy, hilly, unfamiliar backroads. Drivers multitasking with cell phones, laptops, and so forth. I can say something about these things to the guy behind the wheel, but that’s the extent of it. I can’t control another person’s behavior. The only thing I can control is whom I  get into a vehicle with. And that decision is one I will be taking very seriously in the future, because the attitude that person has toward safety can have huge implications for me, those who love me, other passengers, and other motorists who share the same road. Sitting in the passenger seat three weeks ago, I took the main force of the collision, and never again do I want to go through the pain I’ve experienced these last few weeks as a result. And never again do I want to put Lisa through the shock and fear of that awful afternoon, let alone something far worse.

Some of you take huge risks both with the storms and with your driving. And yes, I know: You’re big boys and girls and it’s your decision. It’s a matter of personal choice. Rah, rah and a fist bump for rugged individualism. We’ve all heard it. It’s like a mantra among today’s chasers.

But when something serious happens to you, trust me, you’ll be singing another tune. Because you don’t really know the the implications of your choices until one of them blasts past your bulletproof attitude and inserts itself into your life with jarring and possibly irrevocable immediacy. There goes the storm you were chasing, receding to the east. But what has just happened to you–that may never go away.

Most of you are in your twenties and early thirties. Lots of life still ahead of you. Many chases still in store for you. Don’t blow it. Because if you wind up in a wheelchair for the rest of your life, the best of your chases will leave you with just a handful of memories and decades of wishing you’d been wiser in the way you went about doing things.

Am I saying you shouldn’t take risks? Of course not. Everything worth doing involves some kind of risk. You can’t truly live without risking. But there is a difference between taking judicious and necessary risks versus taking irresponsible, selfish, and totally avoidable risks. Risks that could get you killed. Risks that could get your chase partner killed and leave you haunted with guilt the rest of your life. Risks that could leave you or someone else paralyzed. Risks that could devastate those you’ve left behind–your spouse or significant other, your children, your parents, your siblings, your friends.

The people you say you love and care about.

Other people and their families.

It ain’t all about you.

When I arrived home at 11:30 that night, Lisa greeted me at the door. I’d never seen her act the way she did–one minute laughing, the next minute crying. Gently, she helped me remove my shirt, a painful operation. We stood in the bathroom in front of the mirror. I was pretty banged up. She kept touching me and kissing my shoulders. She laid her head on my shoulder, closed her eyes, and smiled, and I looked in the mirror and smiled back at her from the glass. My woman. “You’re here with me now,” she said. “That’s all that matters. You’re here with me now.”

I knew then just how much she really loves me, how much I mean to her. I can say, in all truthfulness, that it was worth the loss of my car to experience how much closer the accident has drawn us since that awful day. We almost lost each other. But we didn’t. And during the course of my healing, she has taken care of me beautifully. We have laughed (Ouch! It hurts to laugh!), and had deep, heartfelt conversations, and walked with each other through yet one more stretch of deep water. God has brought us through, and as I emerge on the other side, it is with the certainty that he has given me a truly wonderful, beautiful woman who loves me with all her heart. I have much to be grateful for.

To sum it up for you, my fellow chasers: Chase with passion. But also chase responsibly, with wisdom and an awareness of just how vulnerable you are. Because you are vulnerable. And I think that many of you don’t understand what that means. You say that you do, but do you really? Your life truly is a vapor, as passing as those towers of convection which seem so indomitable in the moment but vanish within hours. Today’s chase will be only a memory tomorrow. Chase in a way that does not become a lifetime of regret, whether for you or those who love you.

 

 

 

February 20: The “Everything” Storm System

February 20 2014 Davenport I find this screenshot of the Davenport, Iowa, radar fascinating for its variety. Captured at roughly quarter to five in the afternoon eastern time, it shows just about every conceivable kind of Midwestern weather in operation simultaneously. Tornadoes and funnel clouds. Squall line with embedded supercells. High winds. Hail. Flooding. Snow. Fog. Have I missed anything? If weather systems were baked goods, this one would be an Everything Bagel.*

As I write, the squall line stretches from eastern Indiana all the way down to south central Louisiana and out into the Gulf of Mexico, and it is progressing eastward, continuing to generate high winds, tornado warnings, and flash floods. All in all, quite an active day for this waning February, particularly considering how far north convective weather has occurred. In the face of this winter’s record-breaking snow and cold, today has been a potent harbinger of what this spring, when it finally arrives, may hold. Even here in Caledonia, we got a few rumbles of thunder, though nothing like what folks a few hundred miles south of us have experienced.

The irony of it is, after this, it’s back to winter again. Serious, snowy, cold winter, with no sign of a letup anytime soon. Eventually, of course, the arctic air will retreat, but not without a fight. Today was just a promissory note, a down-payment, on things to come. I’m in no hurry to collect. In fact, I’d just as soon get dumped on–seriously dumped on–just to see how much more snow we can squeeze out of this winter before a warmer pattern sets in. We’ve already experienced unreal; let’s shoot for insane. We’ve come this far, so what the heck, let’s do this thing right.

But then–let’s have spring. I’m lightning-starved and thunder-hungry.

—————————–

* That is one of the worst analogies I’ve ever come up with, but I don’t care. Well, I care enough to write this footnote, but that’s all.

The Day Before Groundhog Day: Yet Another Winter Storm–and More on the Way

Today is February 1, and let’s just say it: This winter is getting reeeaaaally old. Incursion after incursion of Arctic air. Snow, snow, snow. Cold, cold, cold–and I do mean cold. After Monday and Tuesday’s bitter, subzero bite, these mid-twenties temperatures that have moved in feel practically tropical.

Winter_Storm_02012014We’re presently under a winter weather advisory, with 3 to 5 inches of snow forecast through 10:00 p.m. around here and an inch more to the south and southeast along the I-94 corridor. And it’s wet snow–not as bad as initially expected, according to the latest KGRR forecast discussion, but still watery enough–and therefore heavy enough–to put added stress on flat roofs. Here’s a radar image from a few scans back. Look at all that gray! I hardly ever see returns that hit 40 dBZ with a winter storm, but a bit of interrogation revealed 49.5 dBZ over US-131 with this particular scan. And it appears to be all snow too, not a wintry mix. So yeah, I’d call that wet snow.

Snow Depth Feb 1 2014The thing is, this stuff just keeps coming. We all know that by now. I haven’t seen a winter this snowy since 2009, maybe even before that, since . . . since . . . well, I don’t know when. As you can see from today’s snow depth map, there’s a strip running through my area along the western side of Michigan where the snow depth reportedly exceeds 20 inches. We’re not talking about how much snow has actually fallen this winter, just how much of it is presently sitting on the ground. Twenty inches. I can testify that around here, it’s not hard to find places where it’s nearly up to my knees. Heck, just along the sidewalk outside my apartment, the snowblower has neatly carved a minor canyon along the edge of the featureless white expanse which, if my memory is accurate, used to be what is called a “lawn.”

Feb 1 GFS 132-hr fcstHow about one more image? Look and groan, because all this glorious wintry nastiness doesn’t look to be retreating anytime soon. You’re looking at the 132-hour forecast for the surface temperature. Doesn’t that look inviting, so full of hope and promise? Tomorrow is Groundhog Day, and I’m telling you right now, that little cretin had better not show his face anywhere in my vicinity or I will send him into permanent hibernation.

If there’s one good thing about this winter from a personal perspective, it’s that it has inspired me to learn about winter forecasting. There’s certainly every opportunity to do so, and plenty of incentive. So I’ve learned a few new terms. Try this one on for size: heterogeneous nucleation. I like that one. Or how about this: DGZ, which stands for dendritic growth zone, the temperature range between -12 and -18 degrees Celsius wherein a saturated layer produces snowflakes. Got that? I’m starting to, along with a deeper appreciation for my RAOB software program.

But I’d still be glad to see all this snow and cold go bye-bye, and I’ll bet I’m not the only one. Well, well . . . buck up, ladies and gentlemen: meteorological spring is on the way. I just have a hunch it won’t be here March 1. It’s arrival time may be delayed by snow.

What about you? Are you a winter lover or a winter Grinch–or has this winter turned you from one into the other? How do you think this crazy-cold, uber-snowy weather might affect the spring storm season? Drop a comment and share your thoughts.

Rob Dale on Free Learning Resources for the Prerequisites of Meteorology

I owe the following content to meteorologist and Ingham County, Michigan, emergency manager Rob Dale. With his permission, I’m duplicating it here from Rob’s Facebook post, as I think some of my weatherhead readers may find it relevant and useful. That has been my experience; thanks to Rob, I’ve actually begun to look into tackling high school algebra–a subject I did horribly at back in my teen years–with an eye on laying the groundwork for calculus, and thence, meteorology. One is never too old to learn, right?

Perhaps the free resources Rob has listed below will inspire you too to expand your learning horizons. In any case, the legwork Rob has done is too valuable to be buried beneath the Facebook landslide.

Here’s Rob.

Let’s say you’re interested in REALLY learning about meteorology? You have NO idea how many resources are available today compared to just 5-10 years ago! You can take most of the core courses that currently cost thousands of dollars at a university for free at your own pace… For example, a met degree requires Calculus, Physics, and Chemisty off the top. Once you have that background, you can start reading intermediate (and maybe advanced) textbooks and actually learn how to forecast. You still won’t be a full fledged met, but I guarantee you will make better forecasts than now and you will feel better knowing your knowledge is the reason why. You can find them elsewhere, but many of these from MIT have full video lectures which makes the process easier.

http://ocw.mit.edu/courses/physics/ 8.01, 8.02
http://ocw.mit.edu/courses/chemistry/ 5.04, 5.60

Now you’ve got the basics! You can get meteorology books, will understand what you’re reading, and actually start to make sense of the “why” behind the process.

Some of those books can be expensive, but buy one at a time and you’ll be able to sell them for about 80% of what you paid (if not more.)

Does this sound hard? Yup. Necessary if you want to really know meteorology? Yup. Impossible? Nope. Just think how much time you are wasting drawing lines on Microsoft Paint and how those hours could actually help you learn! If you really wanted to be a guitar player would you be better off spending time on Guitar Hero or learning chords on a real guitar? One of them is fun in the short term but offers no advantage towards your goal. Same story here.

So there you go. If this is REALLY your passion, make it something valuable. If you end up going to college, think of how much easier those classes will be since you’ve already invested ahead of time! If you don’t go to school, imagine how much more interactive your conversations can be with meteorologists and how much of a service your posts will be to followers.

Now, if you, like me, totally sucked at any form of math back in your high school daze (daze being a fully appropriate word for a child of the 1970s), Rob has also provided a link to KhanAcademy, which provides a blizzard of tutorials on the prerequisites for college-level courses. And yes, they too are free, free, free.

Considering the education you can get online today without paying a dime, the only thing that can cost a person is to remain ignorant. Learn at your own pace for your own enrichment and satisfaction. What’s to stop you?

Hey, Rob–thanks! You rock, Pilgrim.

 

Maps Coming to RAOB Sounding Software

Welcome to 2014! I’m going to refrain from writing the typical New Year’s Day stuff here, having already shared my greeting and reflections on Facebook. Instead, I want to share  one of the cool new things this New Year has brought in.

For some time now, deep in a hollow tree, John Shewchuk has been hard at work, and now, at last, he has rolled out something that is sure to make your mouth water: worldwide data maps for his RAOB software.

Okay, so it’s not a new cookie and John is not a Keebler elf. What he is, is the creator of the world’s most powerful and versatile atmospheric sounding software, which, thanks to John’s ongoing quest for excellence, keeps getting better all the time.

I am an unabashed RAOB fan, and I’m far from alone. John’s clients, both government and private sector, are legion and worldwide and firm believers in the phenomenal firepower of John’s brainchild. I am probably the humblest and least sophisticated of the bunch, not being a weather researcher or an operational forecaster but merely a layman with an avid interest in storm chasing. I purchased the core software several years ago along with a number of the modules, and I quickly realized that the capabilities of RAOB far outstripped my knowledge of the atmosphere, to say nothing of my technical expertise. I will add that I’ve learned a bit since then, particularly in the first area, thanks in part to RAOB, whose commonsense design has made the meteorological insights that soundings have to reveal easier to access for even a non-tech such as me.

And that underscores what is, in my book, one of RAOB’s most glowing attributes: its ease of use. I don’t have to be a geek in order to make it go. It’s much easier and faster to use than Bufkit, which, though feature-rich and free, I never could figure out. And now, with the addition of worldwide data maps, the RAOB user interface becomes even more intuitive and convenient.

RAOB Map USHere is an example of one of the maps. As you can see from the pulldown menu, there are other options which, altogether, cover the entire globe, including the polar regions. They are the latest improvement to the version 6.5 beta test and apply only to WMO soundings, not forecast soundings such as GFS or NAM. The latest update to the maps completes phase 1 of the mapping project. A recent newsletter stated that “phase 2 will enable creation of cross-sections by just drawing a line across the data maps. ” That will be an immensely useful feature for setting up spatial (versus temporal) cross-sections.

Bottom line: Big kudos and thanks to John–who, by the way, works out of his home in Matamoras, Pennsylvania, not in a hollow tree. Sorry to disillusion you. But if you’re a storm chaser or a weather buff, what he turns out goes far beyond anything the Keebler elves ever dreamed of.

I should add, this is neither a paid nor solicited review. I have written it strictly as a service to fellow storm chasers and because I love John’s work.

Playing the Sax Again after a Forced Hiatus

Back in April 2012, I wrote about how it felt to pick up my sax again after weathering the worst case of bronchitis I have ever experienced. In short, after three miserable weeks away from my horn, it felt wonderful to pick it up again. I was rusty and had a little ground to reclaim, but that was okay; where my technique had suffered a bit, my creativity seemed to move to the forefront, and my playing felt fresh.

A year-and-a-half later, I’m here to share a similar experience. And I’ll begin by saying that I’m truly fortunate–graced, blessed by God–to be able to write about it, because I could be dead. It was no nasty cold that took me down this time but a bad car crash in Indiana last November. Fortunately, no one was seriously injured, but, sitting in the front passenger seat of the car I was traveling in–which was mine but with a friend driving–I took the brunt of the collision. Upon emerging from the car, I could tell that something was wrong with my chest. I felt no pain at the moment, just discomfort, but I had a hunch that would change pretty quickly, and it did.

For the next several days, my chest hurt pretty badly. I figured I had bruised my sternum, perhaps even cracked it, and probably sustained several levels of injury involving my muscles and ribcage. Four or five days later, the pain gradually began to subside, but it took yet another week or so before I was able to cough freely or sneeze without ruining myself for the next hour.

Finally, last week, I picked up my sax for the first time and blew. I’d like to tell you how great that felt, but “great” isn’t the right word. It just felt…normal. Kind of flat, really–like pretty much any practice session in which I haven’t felt particularly inspired but practiced anyway because I needed to. As best I could, I simply picked up where I had left off before the accident, playing through the Bird tunes “Confirmation” and “Ornithology,” including some transcriptions of those solos, and reacquainting myself with a couple of dominant seventh patterns I’d been working on.

But wait a minute. Both of those tunes are pretty complex bebop tunes, and a year ago, I couldn’t even play “Confirmation.” To be able to just jump back in the saddle with it after five weeks of not even touching my horn–that tells me this last year in the woodshed has been a profitable one. I’ve raised my baseline of ability on my instrument; music that once seemed formidable has been internalized.

I’ve had two practice sessions since, and last night’s felt great. Time to work on some new ideas as well as brush up on the stuff I’d been working on prior to the crash.

But here’s the take-away: Developing musical proficiency isn’t about emotion or instant gratification. It’s about discipline. Your practice sessions don’t have to feel creatively inspired; they just have to be consistent. You just have to stick with it. If you do, and if you practice the right stuff, then you’ll grow.

A farmer’s job is to plant his seeds, water them, and nurture them. If he does, then the seed will germinate and grow, and in due time, the farmer will reap a harvest. That’s how it works. It’s not about inspiration; it’s about hard work and dedication, and the same holds true for learning to play jazz or any kind of music. Get your priorities in place and the moments of inspiration will come.

Henryville Tornado: Some Video Captures from the Storm’s Early Stages

This year, 2013, has once again been lousy for me from a storm chasing perspective. My two forays out to Oklahoma and Kansas yielded nothing in terms of tornadoes. Some cool gustnadoes, but that’s it, unless you count a glimpse of a decaying tube so fleeting that it’s barely worth mentioning. My best chase of the year was right here in Michigan. And my worst was unquestionably on November 17 down in Indiana, when a road accident claimed my beloved Toyota Camry.

So since I have nothing to show for this season, I thought I would grab a few stills from my video of the March 2, 2012, Henryville, Indiana, tornado, just to remind myself that I’ve actually had some decent chases. The shots, arranged sequentially, show the tornado from where Bill and I first glimpsed it shortly after touchdown as we were approaching Palmyra from the south, to its intensifying and mature stages north of town, where it tore across SR 135, ripping up a 12′ x 12′ chunk of asphalt in the process, and then raged northeastward toward New Pekin and then its deadly visitation on Henryville.

These are just video grabs, and our vehicle was moving at a good clip as I shot the footage, so the images are by no means tack-sharp. But they still give a pretty good feel of a memorable chase. They’re arranged in proper sequence, so you can see the variations the tornado went through on its way to becoming a raging EF-4 monster.

I intend to add a few more images, but the eleven I’ve included here are most of the show and plenty enough to tell the story. (I don’t know why the one showing the power flash turned out so small; I plan to replace it with a larger image.)
