LT, Thermals really come into play when the wind is very light, as a stiffer wind can somewhat over ride them. Air will flowsimilar to water over the terrain. Air warming up moves up. Air cooling down moves down.

That's one reason I prefer hunting mornings. I feel the air currents are rising with calm to light winds. Pressure also affects air movement.

A lot of variables!! It's just one reason I like having some wind floaters with me. Nothing like watching exactly what the wind is doing for a distance
