Caption: Timelapse footage of a pileus (cap cloud) forming on the top of a developing cumulus cloud. The pileus is caused by fast-moving updrafts forcing moist air above the dew point altitude, causing cloud formation. A pileus cap is a sign of particularly strong updrafts, indicating that the cloud may be associated with a developing thunderstorm. Filmed in the USA in the middle of a summer day.
