Document Summary
Greenhouse gases; co2, n2o, ch4 and cfc. 1. ) heat absorbed between 40 degrees n & s latitudes. The coriolis effect (be sure you understand this phenomenon)- stronger at the poles. Equatorial region has heavy, rain-air movement in doldrums (place at equator where there is no wind) 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). Hurricanes: understand how they form and their physical structure (refer to pages 217- 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. This occurs down to a depth of about 100m, by which point the water is actually moving to the left of the wind.
