The reason being is because winds will move towards each other along the front. The angle of a cold front is also greater than that of the other types of fronts, which creates more lift in the atmosphere vertically.
The bigger the difference of the air mass that it is moving into, higher dew points, temperatures, and upper level winds, the greater the threat for severe weather due to the differences between the air masses as they collide. On the flip side, if there is not a lot of moisture on either side there may not be any rain.

Bluff City Life. About Us. The occlusion starts when a cold front catches up to a warm front. The air masses, in order from front to back, are cold, warm, and then cold again.
Coriolis Effect curves the boundary where the two fronts meet towards the pole. If the air mass that arrives third is colder than either of the first two air masses, that air mass slip beneath them both. This is called a cold occlusion. If the air mass that arrives third is warm, that air mass rides over the other air mass. This is called a warm occlusion. The weather at an occluded front is especially fierce right at the occlusion.
Precipitation and shifting winds are typical. The Pacific Coast has frequent occluded fronts. Remember, a weather front is basically the boundary between two air masses of different densities.
At the center of each air mass is typically a high pressure. This means that weather is typically sunny within air masses, but their temperatures could vary with the season and humidity could vary based on the source region of the air mass. Now more often than not, these weather fronts are not isolated events.
Often times, they are part of a larger rotating system called a mid-latitude cyclone. This type of cyclone will be discussed later in this chapter, but as an introduction it is a low pressure system that is usually mixing warmer air from the south in the Northern Hemisphere and colder air from the north.
