Coriolis Effect

Coriolis Effect

When air moves from high pressure to low pressure, the winds do not take the most direct possible route. They try to, but are deflected sideways. This is due to the rotating movement of the Earth, and is called the Coriolis Effect.
The forces involved have the effect of deflecting the winds in the northern hemisphere to the right of their intended direction, and those in the southern hemisphere to the left. The Coriolis Effect acts on the world's main air movements to determine the directions of the world's main winds. [RA] {WC}
