IV. Wind

A. Basics
  1. pressure (fig. 5-3)
  2. isobars
  3. pressure gradienet
B. Controls
  1. pressure gradient - high to low pressure (perpendicular to isobars) (fig. 5-6)
  2. coriolis effect (focus box pages 110-111)
  3. surface friction
  4. combination (fig. 5-6)
C. Regional variations (fig 5-8)
  1. cyclone - Low in center, ccw
  2. anticlyclone - High in center, cw
D. Global circulation cells (fig. 5-13)
warm air rises, cold air sinks
  1. equatorial low (ITCZ) (fig. 5-36, 5-22)
  2. sub-tropical high; horse latitudes (fig. 5-16)
  3. sub-polar low (fig. 5-32)
  4. polar high (fig. 5-30)
E. Global winds (fig. 5-14, 5-15)
  1. polar easterlies (fig 5-31)
  2. westerlies (fig 5-24)
  3. trade winds (fig 5-18)
  4. doldrums (intertropical convergence) (fig 5-22)
F. Local winds
  1. land/sea breeze - fig. 5-41
  2. mountain/valley breeze - fig. 5-42
  3. monsoon - fig 5-39, 5-40
