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
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
