Roll cloud, timelapse - HD 影片檔
Timelapse footage of a roll clouds at the outflow boundary of a storm system. The outflow boundary is where cold air flowing outwards from the storm meets warmer air, cutting underneath it due to its higher density, and causing it to rise and form a cloud. Filmed in Colorado, USA.
