Description

The movement of air constitutes the general circulation of the atmosphere, transporting heat away from equatorial regions towards the poles, and returning cooler air to the tropics. Atmospheric circulation in each hemisphere consists of three cells - the Hadley, Ferrel and polar cells. High-speed wind fields, known as ‘jets’, are associated with large temperature differences.
