Global winds,satellite-based diagram. The rotation of this Earth globe (dark blue arrow) and the Coriolis effect causes the wind patterns shown. The prevailing winds are the trade winds (tropical easterlies),mid-latitude westerlies,and the polar easterlies. The corresponding cells (arrows at right) are the Hadley cells,Ferrel cells,and polar cells. Between these regions are the high-altitude subtropical and polar jetstreams (green arrows). The satellite cloud imagery shows a large low pressure storm system over the North Atlantic,a tropical hurricane near the Caribbean,and clouds along the inter-tropical convergence zone just north of the Equator | |
