Thanks @Sohel.

Coriolis force occurs when you move away or towards the center of rotation. That is because in a rotating frame of reference, like a rotating disk of five meter across in a playground, when you are halfway between the center and the rim, your rotational speed is half that of the speed on the rim, and in the center it is zero of course.
When you take two steps to the rim you do not yet have the required rotational speed and you therefore, seem to have accelerated sideways against the direction of rotation. When you take more time moving to the rim the sideways acceleration seems smaller, because it takes more time for the rotational speed deficit to build up.

That is why the size of the Coriolis force scales linearly with the radial component of your speed relative to the center of rotation and its direction is perpendicular to the direction to the center of rotation.

How? Please explain.
