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 scale — A scale expressed on transparent material and placed across the isobars to measure the geostrophic wind. See also geostrophic wind speed. Geostrophic wind scale for use with one standard parallel at 60°N … Aviation dictionary
Wind shear — Wind shear, sometimes referred to as windshear or wind gradient, is a difference in wind speed and direction over a relatively short distance in the atmosphere. Wind shear can be broken down into vertical and horizontal components, with… … 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
Wind power forecasting — A wind power forecast corresponds to an estimate of the expected production of one or more wind turbines (referred to as a wind farm) in the near future. By production is often meant available power for wind farm considered (with units kW or MW… … 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
