# Coriolis effect

From Glossary of Meteorology

## Coriolis effect

An apparent force, relative to the earth's surface, that causes deflection of moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the earth's rotation.

Named for Gustav Gaspard de Coriolis (1792–1843), a French mathematician who published a quantitative mathematical work on the subject in 1835.
