Cold Front- Fast moving cold air blows in and pushes the warm air up and cools it. It forms cumulonimbus and cumulus clouds. If there is a lot of water vapor in the clouds then thunderstorms may occur.
Warm Front- Slow moving warm air blows in and collides with slow moving cool air. The warm air rises and forms clouds. If water vapor is present, precipitation may occur.
Stationary Front- A warm air mass and a cool air mass meet, but neither one has enough force to push the other. Huge, high towering clouds form.
Occluded Front- A warm air mass is caught between two cool air masses and is pushed upwards. The cool air masses mix and cause cool temperatures. If water vapor is present, clouds are formed.
