Warm air mass
Body of air that forms over a warm region on earth it has a gental frontal slope and layered stratus clouds. It produces light precipitation over a long period of time.
Cold air mass
Body of air that forms over a cold region on earth it has a steep frontal slope and cumulus clouds develop vertically. It produces storms and heavy precipitation over a short period of time
Fronts
The boundary between air masses of different temperature , pressure, and density
Cold front
Is a warm air boundary with the cold air advancing
Warm front
Is a warm cold air boundary with the warm air advancing.
High pressure system
Is cold sinking air and winds that rotate clock wise (opposite as earths rotation)
Low pressure system
Created by warm air rising and winds that rotate counter clockwise (same direction as earth)
Dew
Water droplets that form by condensation of water vapor
