Document Summary

Winds circulate around low pressure systems in the opposite sense in the two hemispheres two cyclones going on at the same time sep 27 1998 line of clouds marks itcz intertropical convergence zone. Coriolis force and geographic barriers create global circulation cells. Heat is transferred from the equator (surplus of solar energy) to the poles (deficit of solar energy) Coriolis effect causes the simple equator to pole circulation to break up into a series of cells, shown here. Global circulation influences climate patterns and moisture distribution. Equator is hot and tropical although it is not that sunny. A lot of clouds generated because of warm air that cools. Trade winds = easterlies, between equator and 30 degree latitude: from east to west. It is what generates monsoons: monsoons, seasonally reversing winds generated by differences over the land and the ocean, big one is south asian monsoon, happens in the itcz. Post-tropical and extra-tropical weather systems extratropical outside of the tropics.
