Four decades ago when I was getting my U. S. glider pilots license the
textbook we used had a very good discussion of convection. This included
stable and unstable air conditions, the temperature gradients needed
to sustain convection, and how, over the course of a sunny day, convective
currents would rise to greater and greater heights, possibly culminating
in a convective thunderstorm.

I am attempting to locate this book. I do not recall if it was a book
on general aviation meteorology, or specifically on soaring meteorology,
or if it was a meteorology section in a textbook on soaring. I would
appreciate any assistance.

Maybe something that pre-dated Tom Bradbury's book?
