Weather Fronts

Cold Front
Cold fronts form when a fast moving cold air mass runs into a slow moving warm air mass. The denser cold air pushes the warm air up. When the warm air is unable to hold anymore water it lets it all out in the form of precipitation which can be accompanied by clouds.

Warm Front
When slow moving warm air mass and a slow moving cold air mass collide a warm front is formed. The warm air slowly glides over the cold air and also creates rain or snow. Because this front doesn't from as fast as a cold front fog and rain may remain for a couple of days.

Stationary Front
A cold front and warm front meet in middle but neither of them have enough force to move the other anywhere. This is called a stationary front. When the water vapor condenses, rain, snow, clouds, and fog occur and may stay fro multiple days.

Occluded Front
An occluded front is formed when a warm air mass is caught between two cold air masses pushing it up. When this happens snow, rain, fog and clouds form. Temperatures at the ground usually decrease drastically because all the warm air is cut off from the ground.
