Question

how does the Coriolis force vary latitudinally

Answer 1

Coriolis force : an apparent force caused by the earths rotation . The coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the Southern Hemisphere . This is also known as 'FERREL s LAW ' .

Answer 2

The Coriolis force is force that is created by the rotation the earth on its axis and is force that is produced by the tilted nature of the earth and thus as the earth rotates in an anticlockwise direction the movement or flow of the wind direction is to the right in the northern latitude and to the left in the southern latitude and this applies to the movement if the oceanic current also.

As the latitude increase, the speed of the earth decreases and this deflection can also be seen in the formation of the hurricane. This deflection is equal and opposite in the north and southern zones.  

Creating the movement of the westerlies from the sub-tropical latitude to the poles. Thus the poles have a high Coriolis effect and equator has a low effect due to the flatness.
