Answer:
The global winds are Prevailing winds, Trade winds, Polar winds
Explanation:
The large global system is created by uneven heating of the earth's surface from above and below the surface. The pressure is measured from the sea level. The large scale motion of air along with oceanic circulation is derived from thermal energy induced by the geomorphic agent and the sun's potential energy. Movement of these pressure belts from north to south is in the form of cells that are fundamental to the rotation of the earth's heating and cooling. On the basis of altitudinal variations, various latitudinal winds/ cells are formed like the Hadley, Polar and Ferrel cell. The ITCZ divides these into northern and southern parts. The equator is the origin of hadley cell and tradewinds and in mid latitudes from 30 to 60 degrees comes the Westerlies. And from 60 to 90 degrees the polar cells in northand south. The ITCZ is the region of mixing.
