GOKEL:
Try a few eye level passes combined with your contour crawl. This will establish whether you're in upflow (good air) or downflow (bad air). You should do these passes at 50-60 knots so you can pick up visually the apparent pace (groundspeed)for the into wind/out of wind conditions.
If one pass requires 80%Q and you appear to be going quick, then your in downflow/downwind air. If you only need 50%Q and you feel like you have a good walking pace, then you have upflow/into wind air.
As all others have stated previously, take a good mountain course like CHC Penticton. Jan Rustad may taaaaaaaalk slooooooooow but he knows his stuff.
Cheers, OffshoreIgor
PS Took the Penticton course in '87.
