Lenticular Clouds

There is nothing more awe inspiring than nature. Today I came across the image below at the Astronomy Picture of the Day on the NASA site.

The Crystalinks site has this definition:

Lenticular clouds, technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction. Where stable moist air flows over a mountain or a range of mountains, a series of large-scale standing waves may form on the downwind side. Lenticular clouds sometimes form at the crests of these waves. Under certain conditions, long strings of lenticular clouds can form, creating a formation known as a wave cloud.

The image below is from the NASA site, there are more pics on the Crystalinks site.
