Fronts

Stationary Fronts

1. When opposing forces of adjacent air masses of different densities are such that the frontal surface between them shows little or no movement, is called a Stationary Front.

2. Stationary Fronts move less than 6 mph.

3. The winds usually blow parallel on both sides of a Stationary Front: Example: East to West on the north side of the front, and West to East on the south side of the front.

1. There are 2 types of Occluded Fronts. Cold Air Occlusion and Warm Air Occlusion.

2. Occluded means to close or come together.

3. When fronts occlude, the weather system is beginning to dissipate.

4. Cold Air Occlusion: When cold air overtakes and replaces warm air.

5. Warm Air Occlusion: When warm air overtakes and replaces the colder air.

1. During World War One, Norwegian Meteorologists discovered and named fronts after the battlefronts of the war.

2. Overrunning: When warmer less-dense air flows up and over colder more-dense surface air.

3. Back Door Cold Front: Most cold fronts generally move from northwest to the southeast. There are times when a cold front will move from the northeast portion of the United States to the southwest. When this occurs, these fronts bring with them a welcome relief from hot weather in the summer. During the winter the weather becomes cold and dank.
