cyclostrophic wind — ▪ meteorology wind circulation that results from a balance between the local atmospheric pressure gradient and the centripetal force. In small scale low pressure systems, such as tornadoes, dust devils, and waterspouts, the radius of… … Universalium
cyclostrophic wind — A class of wind markedly curved in which the Coriolis force is negligible in comparison with centripetal force. Such a state is possible when the radii of curvature of flow is very small; it normally occurs in low latitudes. Dust devils, water… … Aviation dictionary

gradient wind — Any horizontal wind velocity tangent to the contour line of a constant pressure surface or an isobar. This movement of air is to the result of a combination of three forces: pressure gradient force, geostrophic force, and cyclostrophic force. In… … Aviation dictionary
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
