I'm giving a (paid!) talk Saturday on soaring and soaring meteorology
to a group of power-rated pilots as part of a continuing education
aviation seminar. I have not been able to find a diagram which
depicts flow over a ridge showing both the lift on the upwind side and
the turbulence/sink on the downwind side and hope someone here might
know of one, particularly if available on the internet so I can get a
copy.
