Caption: Lenticular clouds. Time-lapse footage of altocumulus lenticular clouds forming a stack in the sky. Lenticular clouds are also called 'UFO' clouds due to their flying saucer-like appearance. They form this characteristically smooth shape due to air streams forming standing waves of air on the lee sides of mountains. Filmed on a spring afternoon in Colorado, USA.
