The Coriolis Force & Planetary Circulation (Hadley Cells)

Because Earth is a rotating sphere, the linear speed of a point at the equator (~1,670 km/h) is far faster than a point near the poles (~0 km/h). Air moving toward higher latitudes retains its eastward momentum, curving relative to the rotating ground beneath it. The apparent Coriolis acceleration is a_c = 2 * Omega * v * sin(phi), where Omega is Earth's angular velocity (7.292 * 10^-5 rad/s) and phi is latitude. Combined with tropical solar heating, this drives three massive atmospheric circulation loops per hemisphere: the Hadley, Ferrel, and Polar cells.
