Aerodynamic cloud created by mountain

As seen on Sept. 25th - the peak of Grand Teton in stiff winds, creating condensation through pressure changes which are causing cooling. No other clouds around.

Edit: While still 'aerodynamic' in a broader sense, the formation process is different from the one seen on aircraft wings as Skephu points out in the post below; it involves a vertical movement of air on the lee side.
And as M Bornong indicates this is called a "Banner Cloud".

I think they call them Banner Clouds.
Indeed. But here I found a different explanation for their formation:
