Document Summary

Constant high sun and consistent day lengths. Trade winds-winds that converge at the itcz. Ne trade winds in nh, and se trade winds in the. Between 20 and 35* latitude in both hemispheres. Simple explained: generally form as air above the subtropics is mechanically pushed downward and heats by compressing. Was the azores high but has moved into the middle of the. In january, 2 low-pressure cells exist over the oceans around 60* The area of contrast between cold air from higher latitudes and warm air from lower latitudes forms the polar front. Exists all the way around the globe. Very weak-little sun energy to put in motion. Polar easterlies- variable winds, cold and dry, move away. Polar high-pressure cells from the polar region in and anticyclonic direction. Trade winds pick up large quantities of moisture as the return through the hadley circulation cell. Denote the circuit complete by winds rising alone the itcz.
