Utah Windriders Association

Although it was not predicted dc did give up some good rides due to the little known and less understood phenomenon known to some as the orographic pulsation coupled with the upper level rippling creating a deep localized pressure gradient to occur lasting only a few hours.

Right ;*) ;*)

But I did say it would cough up some planers ;*)

Glad you got some

OK, can't resist this.

So George, these pulsations originate from...?

Well, I never knew this forum had a word of the day program:

"Orographic: of or relating to the mountains."

Thanks for the new word!
