Fronts are where two air masses meet and create weather. The four types of fronts are Cold fronts, Warm fronts, Stationary fronts, Occluded fronts.
A cold front is where cold air catches up with warm air and pushes it upwards causing thunderstorms and cooling down the areas it passes.
Warm fronts are where a warm air mass catches up with a cold air mass and climbs over it causing only light rain or snow and warming up the area it passes by.
A stationary front is where a cold air mass and a warm air mass meet and neither can decide who's going to "move over". This cause rain for many day.
An occluded front is where two cold air mass push a warm air mass up causing different amounts of rain for different amounts for time.
