Low Pressure
is where warm air rises usually bringing wet, stormy weather.
High Pressure
is where air sinks giving dryer, calmer conditions
Hadley cell
The cell that drives air around tropical regions
Ferrel Cell
The cell that moves air from 30 degrees to 60 degrees in the mid latitudes
Polar Cell
Weak circulation cell that occurs between 60 and 90 degrees latitude.
Trade winds
steady winds in tropical latitudes that blow toward the equator from the north and south
Prevailing westerlies
winds that blow west to east between 30 and 60 degrees in the northern and southern hemispheres
