I am researching shear wave and thermal wave.

For example, the WI glider altitude record was set by Ted Clausing in thermal wave.

For example, on 4/24/98, bases were 7000 msl, thermal wave took gliders to 16-20,000 msl over lower Michigan, and stacked lenticulars were seen.

If you understand how to predict where shear and thermal wave will occur, I'd be delighted to hear about that!

In any case, if you'll send me dates/locations of thermal-wave flights, and altitudes achieved, and a bit of story about the conditions, this would be wonderful. Attaching a log file would be a bonus.

Thanks!

Thermal waves are pretty well researched subject in meteorology. I did a short paper of thermal waves ages ago and still have a box full of printed articles. Well known glider pilot-meteorologists such as Joachim Kuettner and Tom Bradbury are good starting point for search. They observed thermal waves in 60's and 70's. There was at least one big measurement campaign in US during 80's or 90's. They flew fully instrumented plane several times over convective boundary layer and reported widespread wave occurrence. Model studies followed.
