Coriolis effect

In physics, the Coriolis effect is a deflection of moving objects when the motion is described relative to a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right.
==Coriolis Force==
Coriolis effect is a consequence of the Coriolis force. Coriolis force is an inertial force (or a pseudo-force) which acts on object placed in a rotating frame of reference. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame. 
==Formula==
The vector formula can be given as:
:: F_C = -2m \cdot ( \Omega \times v)
:where 
::m is the mass of the object
:: is the angular velocity vector
:: v is relative velocity between the rotating system and object
This can be rewritten as:
:: F_C = m \cdot a_C 
where a is Coriolis acceleration which is given by: a_C = -2 \Omega \times v
