GEOG 131 Chapter Notes - Chapter 3.10-3.13: Roaring Forties, Polar Easterlies, Horse Latitudes
Document Summary
Hadley cell- low pressure areas linked together in a huge cell of convecting air: one occurs just north of the equator and another just south. Subpolar lows- series of low pressure areas at surface at poles. Polar cell- circulating cell of cold air. Polar easterlies- circular winds from the east in response to the coriolis effect. Polar highs- high surface pressure from very cold air over poles is so dense that it has a tendency to sink vigorously to the surface. Icelandic low- subpolar low in the atlantic. Aleutian low- subpolar low over the north paci c. Westerlies- belt of wind blowing from west to east. Anticyclone- movement of a high pressure area guided by mid latitude westerlies: generally move equator ward as they migrate eastward. Cyclones- traveling low pressure systems: tend to move poleward as they travel west to east across mid latitudes, associate with stormy weather.
