Question on thermals

Are thermals affected by the actual temperature or just whether temps are rising or falling? For example, is there any difference if its 10 degrees rising to 20 or 80 falling to 70?

It's the rate of change in temperature. It's called temperature advection.

Sorry, so to answer your question there should be no difference between the two. The problem is that there are other factors in play, such as ground temperature.

I don't know all the correct terminology but from my experience when the sun hit the ground in the mornings it makes milkweed rise up, and in the evenings when the sun is going down and shadows start getting longer it makes milkweed seem to drop.
