Occluded front

An occluded front occurs when a cold front catches a warm front. There are two types of occluded fronts: the-cold-occlusion front and the
warm-occlusion-front.
A cold occlusion occurs when the air mass behind the occluded front is colder than the air mass ahead of it. A warm occlusion occurs when the air mass behind the occluded front is warmer than the air mass ahead of it.
A cold occluded front is normally more severe than a warm occluded front because the rainfall is heavier, and higher gusts can be expected during the passage of the front. Typically, precipitation occurs on both sides of cold and warm occluded fronts. Also, the cloud and weather sequences are a combination of characteristics of both cold and warm fronts.
