quasi-geostrophic approximation — An approximation to the dynamical equations governing atmospheric flow, esp. the vorticity equation, whereby the horizontal wind is replaced by the geostrophic wind in the term representing the vorticity, but not in the term representing the… … Dictionary of automotive terms
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
Balanced flow — In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected… … Wikipedia
