Atmospheric PressureHigh Pressure- heavier, drier airLow Pressure- lighter, moister airAs air rises, it cools, the humidity condenses, and it rains
Pressure Gradient ForcesAir masses flow from high pressure to low pressure
Coriolis EffectAir masses are deflected due to earths rotation
Differential HeatingAir masses over land heat and cool faster than air masses over water
