Tropical Weather

  • Tropics - region between 23.5 N and S of the equator
  • amount of solar radiation does not vary much from season to season, but is relatively intense
  • winds:
    • are generally NE, E, or SE (easterly trades)
    • tend to be quite weak as well..... why?
    • wind flow is best visualized with streamlines instead of sea-level pressure
  • types of weather systems found in tropics:
    • thunderstorms
    • tropical squall lines/clusters
    • non-squall clusters
    • tropical depressions/storms, and hurricanes
  • baroclinic processes do not occur in the tropics..... why??


What if the average number of hurricanes tripled.  How would the heat and moisture transport by hurricanes change the global circulation, if at all?
