thermal tunnel question

[wmihunter]

is there a thermal tunnel on south facing slopes?

A south facing slope should have a thermal tunnel develop when the wind is steady from the north.... the higher the slope, the more noticeable it normally is.

X2 the only thing I would add is that there will be a thermal wind blowing up hill whenever the sun is shining on the valley floor...
