General Circulation of the Atmosphere
Single-cell model (Hadley, 1735) Assumes:
non-rotating earth uniform surface
Low Pressure at Equator (warm air rising) High Pressure at Poles (cold air sinking) Creates a thermal convection cell
 
 
Three Cell Model Due to earths rotation and other
dynamic factors there are typically 3 primary cells Hadley Cell (tropics) Midlatitude Cell (Ferrel) Polar Cell (polar zones)
