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 ...

This process maintains the global energy balance. Scientists have studied atmospheric circulation and ... This is called the three cell model and can be seen in the diagram below.

This creates the trade winds that blow in subtropical regions. But some of the air that descends from the Hadley cell is drawn ... of oceanic and atmospheric circulation drives global climate ...
