Fronts

Front A boundary between two air masses, resulting in stormy weather. A front is usually a line of separation between warm and cold air masses

Cold Front A boundary between two air masses (one cold and the other warm) moving so that the colder air replaces the warmer air.

Warm Front A boundary between two air masses (once cold and the other warm) moving so that the warmer air replaces the warmer air.

Stationary Front A boundary between two air masses that more or less doesn’t move, but some stationary fronts can wobble back and forth for several hundred miles a day.

Occluded Front A combination of two fronts that form when a cold front overtakes a warm front.
