Earth's Atmospheric Dynamics

The Tropics defined by upward motion, low pressure, surface winds, and net surface heating

Incoming solar radiation is much stronger near the equator than near the poles. Atmospheric circulations develop in response to this unequal distribution. These circulations attempt to equalize this distribution by moving heat from warmer to colder regions. Climate models have to account for these large-scale circulations, such as Hadley cells, and the convective heating shown in this figure.
