Caption: Timelapse footage of the passing of a cold front. A cold front is the leading edge of a body of cold air. Cold air is denser than warm air, so the cold air wedges under the warmer air into which it moves, lifting it and causing the formation of a line of thick cloud and heavy rain. Behind the cold front, the air is clearer and significantly colder. Filmed in Colorado, USA, in autumn.
