Wind is a horizontal flow of air from higher pressure to lower pressure the force that generates wind is called the Pressure-Gradient Force.
Two additional belts of circulating air exist in the temperate latitudes (between 30Â° and 60Â° latitude) and near the poles (between 60Â° and 90Â° latitude). Figure 2: Hadley cells and prevailing winds. Solar warming of the tropics drives atmospheric circulation in three cells. Rotation of the Earth generates Coriolis forces that create the easterly trade winds below 30Â° latitude and polar easterlies above 60Â° latitude.
