A Gliding Mentor series book "Thermals" by Rolf Hertenstein, Ph.D.
1. Imagine that a teenager becomes a full-time glider flight instructor. He instructs full-time for ten years, logs thousands of hours, and earns his Diamond Badge.
2. He earns a Ph.D. in Meteorology.
3. He becomes a research scientist, specializing in atmospheric turbulence, with specific emphasis on thermal analysis, mountain wave analysis, and rotor analysis.
4. He writes a superb book about thermals and convection that non-scientists can understand
The latest book in the Gliding Mentor series - "Thermals" by Rolf Hertenstein, Ph.D. - came about EXACTLY as described above.
What's in it? Just about everything that you ever wanted to know about thermals. From the rankest amateur, and up to and including the finest triple-diamond cross-country pilot, you will find TONS of information about thermals, soundings, thermal waves, and thermal prediction that you can USE to extend your knowledge and your flight performances. In the five months that I spent editing and illustrating this book, I learned LOTS of new things about thermals, convection, the Skew-T, thermal prediction, numeric weather modeling, weather resources on the Web, thunderstorms, and a host of other important topics in its 92 large-format 8.5 by 11-inch pages. And recently, I used what I learned from this book to select the day to fly my Diamond Distance flight - 515 kilometers. Fun!
Thermals are the most common form of lift used by soaring pilots. Historically, the first soaring flights were accomplished by exploiting ridge or slope lift on the upwind side of rising terrain. the discovery of thermals, coupled with advancements in glider structures and design, meant that soaring could progress from local slope-soaring to cross-country flights conducted for many hours, at relatively high altitudes, across vast expanses of terrain
Accurate prediction of soaring conditions presents several challenges to the weather forecasters. very small changes in the atmosphere, such as unexpected cooling of air aloft, or the daytime development of a scattered, rather than broken, layer of high clouds, can turn a day that was predicted to be a marginal soaring day into a very good soaring day. On the other hand, if the actual daytime maximum surface temperature falls of the forecast maximum surface temperature, or if unexpected moisture moves in aloft and forms a sun-blocking layer of stratus clouds,the forecast for a good day of soaring weather falls apart, and pilots are disappointed to find only a smooth, stable-air sled-ride down and out of the sky, right back to the gliderport, without so much as a bump.
