Coriolis Force: An apparent force due to the Earth’s rotation. Causes moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern hemisphere. Coriolis force does not exist on the equator. This force is accountable for the way of flow in meteorological phenomena like mid-latitude cyclones, hurricanes, and anti-cyclones.

The major reason for the Coriolis Effect is the earth’s turning around. As the earth spins in a counter-clockwise way on its axis anything flying or flowing over a long distance above its surface is deflected. This happens for the reason that as something moves generously above the earth’s surface, the earth is moving east under the object at a faster speed.

The Earth completes one turning round per day, so for motions of each day objects the Coriolis force is generally moderately little compared to other forces; its effects generally become visible only for motions happening over huge distances and lengthy periods of time, such as large-scale movement of air in the environment or water in the ocean. Such motions are forced by the surface of the Earth, so only the horizontal component of the Coriolis force is usually important. This force causes moving objects on the surface of the Earth to be deflected to the right (with respect to the way of the journey) in the Northern Hemisphere and to the left in the Southern Hemisphere. As air moves from high to low pressure in the northern hemisphere, it is deflected to the right by the Coriolis force. In the southern hemisphere, air moving from high to low pressure is deflected to the left by the Coriolis force.
