It is a deflecting force experienced due to rotation of earth. Because of Coriolis the air appears to turn towards its right in the northern hemisphere and towards its left in the southern hemisphere. The coriolis always acts in the perpendicular direction of the motion of air. It is zero at the equator and increases towards the poles.
Everyone is familiar with the unremitting force of gravity—its powerful pull toward the center of Earth influences all vertical motion that takes place
