This expands the air, making it less dense which leads to rising air. As this air rises, it cools, this makes the air lose its water vapour as rain. This air then circulates around to roughly 30 degrees north and south. However the wind doesn't flow directly up, because the Earth rotates. This rotation causes the wind to have a higher speed in the Eastern direction relative to the ground at high latitudes (see Coriolis effect), which results in a variety of prevailing winds.
The trade winds are created by hot air flowing upwards and downwards from the equator, where it gradually cools until it gets to latitudes of about 30 degrees. It then sinks down towards the surface and flows back towards the low-pressure zone at the equator. These flows are known as HADLEY CELLS, named after George Hadley who first described them in 1753. They are responsible for the dry weather patterns at the 30 degree latitudes, where the majority of the Earth's deserts lie.
Not all of the air moves back towards the equator however, and some continues towards the poles, until it reaches the 60 degree latitude where it meets cold air from the poles. These winds are known as the westerlies. At this point, the warm air rises and most flows back towards the 30 degree latitude. This creates the Ferrel cells.
The final regions are at the poles, from the 60 degree latitude to the 90 degree latitudes. This wind cools towards the poles and sinks to the surface, and recirculates. This creates what are known as the POLAR HADLEY CELL or POLAR CELL.
