Pressure Decreases
Light Patchy Rain
Warm Fronts
Slower than cold fronts
Separates warm humid areas from cold dry areas
Less Dense Air Mass
Cirrus Clouds Often
Rain or Snow
Stationary Fronts
Does Not Move
Warm and Cold Air Masses Move Parallel to each other
Air Masses
Formation
An air mass is a large body of air that has relatively uniform temperature and moisture
conditions at any given altitude. Air masses can be 1,000 km or more across, several kilo-
meters thick, and extend through 20° or more of latitude.
