Both warm front and cold front are considered to be boundaries between two different air masses. A warm front occurs when a warm air mass moves over a cold air mass, while a cold front occurs when a cold air mass moves and replaces a warm air mass. In both cases, there is a boundary of different temperatures and densities between the air masses.
