The Coriolis effect makes storms swirl clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. Because earth rotates on its axis circulating air is deflected towards the right in the northern hemisphere and towards the left in the southern hemisphere this effect called Coriolis effect.
Hurriances spin counterclockwise because the Coriolis effect. The equator rotates faster than other area of earth's surface and moving in a straight line on north to south axis will curve.
In southern hemisphere currents are deflected to the left. Storm system seem to rotate clockwise. This force is caused by the earth rotation and responsible for air being.
