The direction of Coriolis force in Northern Hemisphere and Southern Hemisphere.

Background:Coriolis force is an inertial force  that acts on objects that are in motion relative to a rotating reference frame. A commonly encountered rotating reference frame is the Earth. The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. This force causes moving objects on the surface of the Earth to be deflected to the right (with respect to the direction of travel) in the Northern Hemisphere and to the left in the Southern Hemisphere. The horizontal deflection effect is greater near the poles and smallest at the equator, since the rate of change in the diameter of the circles of latitude when travelling north or south, increases the closer the object is to the poles. Winds and currents tend to flow to the right of this direction north of the equator and to the left of this direction south of it.Water go down the sink counterclockwise in the northern hemisphere and clockwise in the southern hemisphere as is shown in the video. The effects of Coriolis force is also noticeable for motions such as movement of air in the atmosphere or water in the ocean or river.
