The surplus of heat at the equator and the deficit at the Poles drives our atmospheric instability. Instability is a good thing! Without the unstable conditions, there would not be any atmospheric motion. The overheating of the equator pumps atmospheric uplift. As the air rises into lower pressures, it expands and cools... adiabatic cooling! The air migrates north and south and becomes denser than the surrounding air and sinks. The sinking air enters higher pressures and creates the subtropical high pressures and adiabatic heating...whaaaa-la! We have Hadley Cells! Not to mention, the Rainforests and World's largest deserts too! We now can imagine the Hadley cells in three-dimensions. They more or less "sandwich" the equator during the spring and fall equinoxes. However, what happens in the summer and winter? mP Maritime polar…arrow_forward
