A cold front is where the cold air sinks ( because it is denser than the warm air ) and pushes up the warmer air. This front causes severe thunderstorms and cold weather. The cold front creates clouds that move upward in this specific order; Cumulonimbus, Nimbostratus, Altostratus, and then finally, Cirrus. As the cloud moves upward the rain starts to cease until there is no more.
A warm front is when the warm air pushes the cold air up. This front brings warm and moist air. A warm front has clouds that progress as they work their way up through the troposphere starting with Nimbostratus then Altostratus and then after that Cirrostratus and lastly Cirrus.
A stationary front is when a warm and cold front collide and neither one has the power to push the other up. This front causes rainy weather.
An occluded front is when two cold fronts push a warm front up. This front causes rainstorms and clouds.
