Geostrophic wind — The geostrophic wind is the theoretical wind that would result from an exact balance between the Coriolis force and the pressure gradient force. This condition is called geostrophic balance. The geostrophic wind is directed parallel to isobars… … Wikipedia
Geostrophic — A geostrophic current results from the balance between gravitational forces and the Coriolis effect. The gravitational effect is controlled by the tilt of the sea surface and water density is controlled by horizontal changes in temperature and… … Wikipedia
geostrophic motion — ▪ atmospheric science fluid flow in a direction parallel to lines of equal pressure (isobars) in a rotating system, such as the Earth. Such flow is produced by the balance of the Coriolis force (q.v.; caused by the Earth s rotation) and the … Universalium
