A weather front is a boundary separating air masses of several characteristics such as air density, wind, and humidity. Disturbed weather often arises from these differences. The direction of movement is often guided by high winds, such as Jet Streams and landforms like mountains can also change the path of a front. There are four different types of weather fronts, cold fronts, warm fronts, stationary fronts, and occluded fronts. When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms and they move fast, up to twice as fast as a warm front. As a cold front moves into an area, the heavier, more dense, cool air pushes under the lighter, less dense, warm air, causing it to rise up into the troposphere. Lifted warm air ahead of the front produces cumulus or cumulonimbus clouds and thunderstorms, like this photograph shows.
