Describe the coriolis effect and its cause?

Answer 1

The Coriolis effect is an apparent deflection of moving objects when they are viewed from 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 anti-clockwise rotation, the deflection is to the right.

The Coriolis effect is caused by the rotation of the earth and the inertia of the mass experiencing the effect. Newton's laws of motion govern the motion of an object in a (non accelerating) inertial frame of reference. When Newton's laws are transformed to a rotating frame of reference, the Coriolis and centrifugal forces appear. Both forces are proportional to the mass of the object. The Coriolis force is proportional to the rotation rate and the centrifugal force is proportional to its square. 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. The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame. These additional forces are termed either inertial forces, fictitious forces or pseudo forces. They allow the application of simple newtonian laws to a rotating system. They are correction factors that do not exist in a true non accelerating "inertial" system. The Coriolis effect causes the large air masses in the atmosphere to rotate, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as large-scale movement of air in the atmosphere or water in the ocean. Such motions are constrained by the 2-dimensional surface of the earth, so only the horizontal component of the Coriolis force is generally important. This force causes moving objects on the surface of the Earth to appear to veer to the right in the northern hemisphere, and to the left in the southern.

Contrary to myth the rotation of water going down the drain is not influenced by the Coriolis effect (the forces are much too small at that scale).

Answer 2

The Coriolis effect is the result of the differences in ground speed as the Earth rotates. It impacts the large-scale movement of air by deflecting all the wind movement to the right of their intended path in the Northern Hemisphere.
