a force which, due to the Earth's rotation, acts on a body in motion; an apparent force deflecting the motion of an object or a fluid moving over the surface of a rotating body such as a planet or star
from C.G. Coriolis, French mathematician and engineer
1969 (earlier Coriolis force, 1923, and other references back to 1912), from the name of French scientist Gaspard Gustave de Coriolis (1792-1843) who described it c.1835.
|Coriolis force |
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 |
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).
