Step-by-step explanation:
The air in the Earth’s atmosphere moves from high pressure to low pressure. On a rotating body such as the Earth, the air turns to the right—counterclockwise—in the Northern Hemisphere and to the left—clockwise—in the Southern Hemisphere. The rotation creates friction, called the coriolis force, between the air and the Earth’s surface which breaks up the air circulation between the equator and the poles into three different mirror-image wind systems on each side of the Equator. Since the coriolis force is zero at the equator, the effect is therefore more pronounced for longitudinal motion, a North-South wind, than for latitudinal motion, an East-West wind.
