coriolis force in Science

Coriolis force

  1. A velocity-dependent pseudo force used mathematically to describe the motion of bodies in rotating reference frames such as the Earth's surface. Bodies moving on the plane of rotation appear to experience a force, leftward if the rotation of the reference frame is clockwise, rightward if counterclockwise. Such motion gives rise to the Coriolis effect.

Coriolis effect

[kôr′ē-ōlĭs]
  1. The observed effect of the Coriolis force, especially the deflection of objects or substances (such as air) moving along the surface of the Earth, rightward in the Northern Hemisphere and leftward in the Southern Hemisphere. The Coriolis effect is named after the French engineer Gustave Gaspard Coriolis (1792-1843).

An apparent force ultimately due to the rotation of the Earth. It is the Coriolis effect that makes the air in storms rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
