I've picked up the book authored by Jean-Marie Clément, Dancing With The Wind. He makes a point regarding valley breezes channeled by mountains becoming either dextrorotatory vs levorotatory. Supposedly, climbs will be better on mountains facing the valley breeze on a levorotatory rotation of the breeze (in the northern hemisphere). Any high time experienced alpine soaring pilots care to venture their opinion on this topic? Any specific examples?

Man, I haven't heard the words, "dextrorotary" and "levorotary," (spelled the way we did) since organic chemistry in college! Brings back fond memor.. oh, wait...

And, sorry, I don't have any experience with this.
