When air masses meet. When a moving cold air mass meets a warm air mass, that is lighter, it tends to wedge below the latter, thus giving origin to a cold front. The warm air is forced upwards and its ascent causes the formation of clouds.
A warm front is the surface boundary between a warm air mass and a cold air mass it is overtaking. The warm air moves into an area of colder, drier air.The air masses do not readily mix; therefore the warm air rises slowly over the colder air because it is less dense. warm front is the surface boundary between a warm air mass and a cold air mass it is overtaking.
