The air moves towards the equatorial low-pressure zone, and warms up when it meets the land or ocean. At around 60° this warmed air rises. This is another thermally direct cell.

The work produced by that engine causes the motion of the masses of air and in that process, it redistributes the energy absorbed by the Earth's surface near the tropics to the latitudes nearer the ...

As warm air rises and cold air sinks it forms three atmospheric circulation cells north of the equator and three to the south. These circulation cells move over land and sea to redistribute the ...
