Document Summary
Air mass- extensive body of air that has relatively uniform properties in the. Any given altitude in the air mass physical characteristics. Temp, humidity, and stability are all homogenous. When it moves it must retain its original characteristics and not. Be torn apart by differences in air flow. Source region- latitude of the source region correlates directly with the temperature of the air mass, and the nature of the surface strongly influences the. Stationary front- no advance of air masses. Occluded front - cold air overtakes warm air. Move faster than warm fronts because the dense, cold air mass easily displaces the lighter, warm air. Combination of steeper slope and faster advance leads to. Rapid lifting and adiabatic cooling for the warm air ahead of the cold. Stable = cold above and warm below. More gentle than that of a cold front. Warm air pushes against and rises over the retreating cold.
