The diagrams of January and July mean sea-level pressure reveal that, on the average, certain geographic locations can expect to experience winds that emanate from one prevailing direction largely dictated by the presence of major semipermanent pressure systems. These curvy waves are known as Rossby waves. "Polar easterlies" are winds near the poles that blow in an easterly direction. What are the winds at the equator called? The Polar Easterlies are dry prevailing winds that blow from also called Polar Hadley cells. There is Ferrels law derived from Coriolis Effect, which says that in northern hemispheres, wind deflects towards the right and in southern hemisphere wind deflects towards left. A west wind comes from the west and blows east. The direction of wind is also affected by coriolis affect. They are next to the prevailing westerlies. The resultant balance between the pressure force and the Coriolis force is such that, in the absence of surface friction, air moves parallel to isobars (lines of equal pressure). Unlike the westerlies in the Normally the air becomes colder as the height above the Earth increases. If they move from east to west, they are called easterlies.

There are three primary circulation cells on earth known as the Hadley cell, Ferrel cell, and Polar cell. Not all of the air moves back towards the equator though. The Coriolis force explains why winds circulate around high and low pressure systems as opposed to blowing in the direction of the pressure gradient.
