February's Picture

Image From APOD - Lenticular Clouds Above Washington

Lenticular clouds are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction, and sometimes under certain conditions the Lenticular Clouds can form, creating a formation known as a wave cloud.

This image of a spectacular cluster of Lenticular Clouds was taken last December, when during some days the city of Seattle, Washington, USA, was treated to an unusual sky show when lenticular clouds form near Mt. Rainier, a large mountain that looms just under 100 kilometers southeast of the city.
