[QUOTE="Mysticplayer, post: 124421, member: 8947"] Thermals are most 'active' when there are large swings in ground vs air temp. An approaching cool air mass over a hot field will cause bubbles. As would the sun poking out from behind clouds quickly heating the ground. Also, rapid changes in wind speed or direction ARE indicators of thermals lifting off or downdrafts filling in the air that just left. Days with lightish winds will have these conditions more pronounced then a day with steady winds from a certain direction. Oh by the way, thermals will move across large spans of terrain/prairie 'sucking' up air in their path. Think very mild tornado with a really fat butt/base. The backside of this is equally strong downdrafts. Grab a book on R/C glider flying and they will give you lots of info and tips about thermals. Jerry [/QUOTE]
