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
cyclostrophic force — That experienced by wind following curved isobars acting in addition to geostrophic wind along isobars, according to Buys Ballot’s Law. At the equator, the geostrophic force vanishes, leaving pure cyclostrophic wind. See cyclostrophic wind … 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
