Document Summary
How solar energy input varies with latitude: equal amounts of sunlight are spread over a greater o surface area near the poles than the tropics. Ice near the poles reflects much of the energy that reaches the surface there. In the northern hemisphere air turns to the right. In the southern hemisphere air turns to the left: the effect depends on the observer"s frame of reference. Atmospheric circulation cell: a large circuit of air: three cells exist in each hemisphere, air moves in cells influenced by the coriolis effect. Hadley cells: tropical cells found on each side of the equator. Polar cells: found near the poles: wind patterns found within cells. Doldrums: calm equatorial areas where hadley cells converge. Trade winds: surface winds of hadley cells. Hemisphere and to the left in the southern hemisphere. Sea breeze: cool air from over the water moving toward land: occurs after sunrise.
