Occluded Front

There are two cold air fronts on each side and warm air comes and gets pushed up each side of the cold fronts and creates a cloud and rains.

Stationary Front

When a stationary front happens, an equal amount of cool air and warm air fight against each other and they move back and forth equally and create a storm cloud and it rains.

Warm front

When a warm front occurs there's cold air and then warm air starts o come in against it and pushes the cold air over and up and then the warm air goes up slowly and creates a cloud and starts to rain.

Cold Front

When there's a cold front, what happens is there's warm air, and then cold air comes in and makes the warm air rise and they're opposite from each other and the cold air stays low to the ground and it creates clouds and then it rains.
