Document Summary
Heat input to earth; heat absorbed between 40 degrees n & s latitudes. The coriolis effect (be sure you understand this phenomenon). Atmospheric circulation around the earth; know the major wind belts, why they are located where they are, and how the coriolis effect plays a role. Equatorial region has heavy, but brief rain-air movement in doldrums is upward thus being cooled yielding rain: mid latitudes have air masses that are either cold (polar) or warm (tropical) and originating over either water (wet) or land (dry). Understand how they form and their physical structure (refer to pages 217-223 for explanations). Wind driven by the trade winds and the westerlies, and are predominately east-west. Land and the coriolis effect deflects the currents creating a circulatory motion to the ocean termed a gyre. These n-s flowing currents are referred to as boundary currents.
