The Coriolis force is an apparent force caused by the Earths rotation. It is responsible for the deflection of winds towards the right in the Northern Hemisphere and towards the left in the Southern Hemisphere, which is also known as Ferrel's Law. The deflection is more when the wind velocity is high. The Coriolis force acts perpendicular to the pressure gradient force, which is perpendicular to an isobar. The higher the pressure gradient force, the more is the velocity of the wind and the larger is the deflection in the direction of wind.

The Coriolis effect is also observed in ocean currents and the atmosphere. It describes the pattern of deflection taken by objects not firmly connected to the ground as they travel long distances around the Earth. In the Northern Hemisphere, circulating air is deflected towards the right, while in the Southern Hemisphere, it is deflected towards the left. The Coriolis force is determined by the mass of the object and the object's rate of rotation. It is named after the French mathematician Gaspard Gustave de Coriolis, who studied the transfer of energy in rotating systems like waterwheels.
