Weather fronts

weather fronts include:
Cold Front
Warm Front
Stationary Front
Occluded Front

Cold front: A cold front happens when a fast moving cold air mass runs into a slow warm air mass. Then the warm air rises above the cold air. As it rises it cools causing clouds to form. Then if there was any water in it it would precipitate. And since strong wind is usually accompanied with cold air masses then you have a storm.

Warm front:
A warm front happens when a fast moving warm air mass runs into a slow cold air mass. Then the warm air rises above the cold air. As it rises it cools causing clouds to form just like in a cold front. And since strong wind is usually accompanied with cold air masses then you have a storm.

Stationary Front : A stationary front happens when two slow moving cold and warm air masses meet and neither has the force to push the other. This can cause storms for days at a time.

Occluded Front: A Occluded Front is the most complicated fronts. It happens when a warm air mass is stuck in between two cold air masses. The warm air is pushed of the ground causing cold weather and snow.
