Zonal flow (plasma) — In toroidally confined fusion plasma experiments the term zonal flow means a plasma flow within a magnetic surface primarily in the poloidal direction. This usage is inspired by the analogy between the quasi two dimensional nature of large scale… … Wikipedia

Zonal and poloidal — In magnetic confinement fusion the zonal direction primarily connotes the poloidal direction (i.e. the short way around the torus), the corresponding coordinate being denoted by y in the slab approximation or θ in magnetic coordinates. However,… … Wikipedia
zonal wind — The wind, or wind component, along the local parallel of latitude, as distinguished from the meridional wind. The zonal wind is a large scale west erly wind that is neither cyclonic nor anticyclonic. Upper zonal flow over the North Atlantic with… … Aviation dictionary
Mean flow — In fluid dynamics, the fluid flow is often decomposed into a mean flow – and deviations from the mean. The averaging can be done either in space or in time. In the atmospheric sciences, the mean flow is taken to be the purely zonal flow of the… … Wikipedia
Meridional flow — pattern of October 23, 2003. Note the amplified troughs and ridges in this 500 hPa height pattern. Meridional flow is a meteorological term meaning that the general flow pattern is north to south, or south to north, along the Earth s longitude… … Wikipedia
