Thanks Genghis, just what I need.
As background I was taught to draw up forecasts from station reports in 1970. Practical experience showed me that aviation forecasts were often inaccurate. In the 90s I got back into gliding and then mountain flying including wave systems which was another ball game and although one of our club members was a meteorologist who lectured internationally his practical knowledge was limited. The micro meteorological aspects of paragliding is something else and has come a long way from the sleigh rides of the 80s to flights of 600km and altitudes of 25,000ft.
