Upslope winds forming storms, timelapse - HD 影片檔

Timelapse footage of a classic summer weather pattern near mountains. The hot sun heats the ground and causes the air to rise, forming a layer of cloud. Air rising above mountains draws up air from lower levels. This convection produces tall clouds, such as those seen growing midway through the clip, which can produce heavy rain and thunderstorms. Filmed in Colorado, USA, in summer. Mastered from originals, frame size 1280x1080.
