Coriolis force

Quick Reference

An apparent, rather than real, force which causes the deflection of moving objects, especially of air streams, through the rotation of the earth on its axis. It shows up, for example, in the movement of an air stream, relative to the rotating earth beneath it. The Coriolis force is proportional to the wind speed U(z), and the Coriolis parameter, f   =  2 Ω sinΦ—where Φ is the latitude and Ω is the Earth's rate of rotation—and acts perpendicular to the wind direction (Orr et al. (2005) Weather 60, 10).
