Tell me why winds are deflected more at the poles than at the equator?

Hint:
The force which deflects the direction of wind is called the deflection force or Coriolis force. This force generates due to the rotation of Earth. This force is zero at the equator and maximum at the poles due to the rotation of earth where Earth moves west to east or westward.

Complete answer:
 Due to Coriolis force, objects deflect to the right in the northern hemisphere as well as objects deflect to the left in the southern hemisphere. So, winds are affected more at the poles rather than at the equator.

It is an effect whereby a mass moving in a rotating system acts perpendicular to the direction of motion and to the axis of rotation. and also it is directed at the right angle to the direction of flow of air. On the earth, the effects are also important in the formation of a cyclonic weather system. Coriolis force affects only wind direction not the wind speed or velocity and it is also directly proportional to speed of wind. Hence, Coriolis force is strong at poles and weakest at equator.

Note:
The Coriolis force is an inertial force which acts that object which is in the motion with the frame of reference that rotates with respect to an inertial frame. We can see, when Coriolis force is act in northern hemisphere at object, then that object rotate in anti-clockwise direction and when force is applied in southern hemisphere at object, then that object rotate in clockwise direction and object is not rotate at just equator. And there is no effect of Coriolis force on velocity of object.
