effect moving air or water is deflected horizontally because the speed of rotation of the Earth's surface is faster at low latitudes then at high latitudes. The Coriolis effect acts to the left in the southern hemisphere, imparting a clockwise swirl into an are of low pressure. There is little Coriolis effect within 7o of the equator.

Coriolis effect [for Gaspard Coriolis], tendency for any moving body on or above the earth's surface to drift sideways from its course because of the earth's rotational direction (west to east) and speed, which is greater for a surface point near the equator than toward the poles. In the Northern Hemisphere the drift is to the right of the motion; in the Southern Hemisphere, to the left. In most human-operated vehicles, continuous course adjustments mask the Coriolis effect. The Coriolis effect must be considered, however, when plotting ocean currents and wind patterns, as well as trajectories of free-moving projectiles through air or water.

The deflection a parcel of air takes relative to the Earth's surface due to Earth's rotation.

Force An apparent force due to the Earth's rotation. Causes moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern hemisphere. Coriolis force does not exist on the equator. This force is responsible for the direction of flow in meteorological phenomena like mid-latitude cyclones, hurricanes, and anticyclones.

Coriolis is a lunar impact crater that is located on the far side of the Moon. The crater floor is bisected by the lunar equator, and it lies about three crater diameters northwest of the Daedalus crater.

The Coriolis satellite is a Naval Research Laboratory and Air Force Research Laboratory earth and space observation satellite launched from Vandenberg Air Force Base, on 2003-01-06 at 14:19 GMT.
