Occluded Fronts

An occluded front is formed when a warm and cold front meet. When this occurs, the warm air from the warm front goes over the cold air from the cold front; through the process of baromteric pressure. This is now aa Occluded front. When the warm front keeps rising, it starts to condensate, forming a Cumulonimbus cloud. This cloud, packed with rain droplets, drops them, causing it to rain and in some cases to cause thunder and lightning.
