Definition of Coriolis Effect
Coriolis effect is a pattern of deflection that is taken up by the objects which are not firmly held to the ground. These objects are not fully connected to the surface as they have to travel long distances around the Earth. The large scale weather patterns are due to this effect. The basis of the Coriolis effect is the rotation of the Earth.
The rotation of the earth is faster near the equator as compared to the poles. High velocities and long distances make the impact of the Coriolis effect quite prominent. The trade winds as well as the cyclones are the result of the Coriolis effect.
