Document Summary
Fronts: are boundary surfaces that separate air masses of different densities: types of fronts, cold. Cold, dry air replaces the warm, moist air. Large changes in temperature over a short distance. Cloud and precipitation patterns: warm, stationary. A nearly stationary(not moving) boundary between two air masses. The airflow on both sides of a front is neither toward the cold air mass or warm air mass, but instead parallel to the line of the front. Weather: expect to have clear or cloudy skies with possible light rain: occluded. Backdoor cold fronts: cold fronts that move in the direction from the east, or northeast (regular cold fronts tend to move toward the south, southeast, or east). The precipitation stops and most of the clouds clear(some stratocumulus will remain) Occluded fronts: form with a cold front catches up to a warm front. Cold-occluded front (cold occlusion: the air behind the cold front is colder than the air ahead of the warm front.
