Global Circulation Systems

I. HADLEY CELL

A.   Conditions

  1. no land/water (all water)
  2. no seasons (sun over equator)
  3. no rotation (only pressure gradient)
B.   Results = Hadley Cell

II. THREE CELL MODEL

A. Global Pressure / Circulation Patterns

  1. intertropical convergence zone (ITCZ) - "doldrums" (seasonality)
  2. subtropical high (STH) - "horse latitudes"
  3. trade winds
  4. westerlies
  5. subpolar low
  6. polar easterlies
  7. polar high
B. Peripheral Terminology
  1. jet stream
  2. thermal low
  3. ocean currents and upwelling
  4. El Nino / Southern Oscillation (ENSO)
    • La Nina ... "La Nada"
  5. "La Mama" or PDO (Pacific Interdecadal Oscillation)
