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
geostrophic wind speed — The speed of a geostrophic wind calculated from the pressure gradient, air density, rotational velocity of the earth, and latitude. The calculation ignores the curvature of the wind’s path. A geostrophic wind is proportional to the pressure… … Aviation dictionary
geostrophic force — The force acting on the wind at right angles to its direction of motion, from left to right in the Northern Hemisphere and from right to left in the Southern Hemisphere. See also geostrophic wind … Aviation dictionary
climate — /kluy mit/, n. 1. the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years. 2. a region or… … Universalium
gradient wind — /wind/ a wind with a velocity and direction that are mathematically defined by the balanced relationship of the pressure gradient force to the centrifugal force and the Coriolis force: conceived as blowing parallel to isobars. Cf. geostrophic… … Universalium
hydrologic sciences — Introduction the fields of study concerned with the waters of the Earth. Included are the sciences of hydrology, oceanography, limnology, and glaciology. In its widest sense hydrology encompasses the study of the occurrence, the… … Universalium
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
