Define Coriolis Force?
Coriolis Force, named after the French scientist Gaspard-Gustave de Coriolis, is also called the Ferrel’s Law, is an apparent, inertial and fictitious force caused by the motion of an object within a frame of reference.
It states that when the Newtonian laws of motion are to be used in a rotating body’s reference, an inertial force shall act towards the right on a counterclockwise rotating body and towards the left on a clockwise rotation body.
Coriolis force is used to explain the force caused by the Earth’s rotation. Deflection towards the right and left is caused by the motion in the northern and southern hemispheres of the earth respectively.
This deflection is dependent on the wind velocity. It shares a directly proportional relation where when the velocity is high, the deflection will be more too. The velocity of wind is dependent on the pressure gradient force, where the higher the pressure gradient force is, the more will be the velocity and hence, causing a greater deflection as well.
