Document Summary
The earth"s climate is driven by solar energy input. The timing and amount of energy received at different locations on the planet are the main factors controlling local climate. Butmotions in the fluid earth (atmosphere and hydrosphere) act to redistribute this energy and produce the wide range of climate variations seen on our planet. Seasonal temperature changes are determined by orbit around the sun. The equator (i. e. , manaus, brazil) receives nearly the same solar energy all year; the poles have the most difference between summer & winter. This is a result of the earth spinning on its axis. Any fluid moving across the surface is deflected clockwise in the northern hemisphere and counterclockwise in the southern. Average global wind patterns arise from a combination of atmosphere rising & falling and the. A combination of heat movement and coriolis effect also drives ocean currents. Even the deep ocean is involved since the ocean also circulates in 3d.
