Mountain clouds, timelapse - HD 影片檔

Timelapse footage of a classic display of low, middle and high clouds downwind of mountains. Air is forced over the mountains as it blows over them, setting up a series of waves downwind of the mountains. This leads to the formation of rows of clouds, lenticular clouds (as at upper left) and high cirrus clouds. Filmed downwind of the Front Range of mountains in Colorado, USA, in spring.
