Answer :

Winds get deflected from their normal path  due to Coriolis Force.
This Force was first discovered by Coriolis, a French mathematician. later it was elaborated by  Ferrel and hence also called as Ferrel's law.

This law sates that, "Due to rotation of Earth, moving bodies like ocean currents and winds get deflected from their normal path  to the right of their course in the northern hemisphere and to the left of their course in the southern hemisphere".
The winds get deflected from their normal path due to the Coriolis Force or in other words the Coriolis Effect. The winds in the Northern hemisphere gets deflected towards the left and that in the Southern Hemisphere gets deflected towards the right. The Coriolis effect is caused by the rotation of the earth. It is important in the formation of all kinds of weather system and in understanding the concept of Global Wind pressure belts.
