What is Coriolis Force?

It is an element in meteorology. It acts on the atmosphere and is caused by the rotation of Earth, which rotates on its axis from west to east with an angular velocity of 15 degree per hour and gives rise to an apparent force called Coriolis Force or geostrophic force. It acts at right angles to the wind vector, to the right in the northern hemisphere and to the left in the southern hemisphere. It was first postulated by a scientist named Coriolis.

Coriolis Force occurs whenever a rotating body moves along a curved path. Hence, two rotary movements (rotation on its axis and precession about a line) are necessary conditions. Whenever a vehicle in motion takes a turn, the wheels rotate about their axis and the entire vehicle, including the wheels, goes round the bend, resulting in Coriolis Force. This is the most common occurrence of this force.
