Thanks for your response Chris.

I understand there are industrial flow meters
relating to "von Karman 'shedding vortices' "
The higher the velocity of the flow the higher frequency caused by the vortices.
There are both obsticals and sensors located inline in the pipe.
This is used for flow control in like milk flow in a cheese processing plant.
Possibly you can tell the wind speeds aloft by
observing those indications around the mountains.

I have relatively small mountains close to here
but about 50 miles or so away is what is
called the Mogollon Rim..."Muggyon Rim" which i think
is a very high scarp relating to the Colorado Plateau.

I have never thought of it before but possibly this could be
a closer source for microseimic noises.
