zonal flow - (Also called zonal circulation.) In meteorology, the flow of air along a latitude circle; more specifically, the latitudinal (east or west) component of existing flow. Compare meridional flow; see zonal index.
Zonal flow
Large-scale atmospheric flow in which the east-west component (i.e., latitudinal) is dominant. The accompanying meridional (north-south) component often is weaker than normal. Compare with meridional flow.

Large-scale atmospheric flow in which the east-west component (i.e., latitudinal) is dominant. The accompanying meridional (north-south) component often is weaker than normal.
ZONAL INDEX The measure of the strength of the westerly winds of the middle latitudes. It is expressed as the horizontal pressure difference between 35 degrees and 55 degrees latitude, or as the corresponding geostrophic wind.
Zonal Flow: Large-scale atmospheric flow in which the east-west component, i.e., flow parallel to the latitude lines, is much greater than the meridional (north-south) component. Compare with meridional flow.

Zonal flow pattern Flow of the planetary-scale westerlies almost directly from west to east; westerlies exhibit little amplitude.
zonal wind—A west wind; the westerly component of a wind. Conventionally used to describe large-scale flow that is neither cyclonic nor anticyclonic.

zonally-averaged models Statistical-dynamical or energy-balance models in which only the latitudinally averaged quantities are determined and the effects of the longitudinally varying transports are determined parametrically.
Zonal and Meridional Meteorologists will often use the terms "zonal" and "meridonial" to describe the upper level wind patterns which indicate the trajectory of air masses and weather systems.
maximum zonal westerlies"The average west-to-east component of wind over the continuous 20- degree belt of latitude in which this average is a maximum. It is usually found, in the winter season, in the vicinity of 40-60°N latitude.

Zonal Flow - It's when the winds in the upper levels of the atmosphere blow from coast to coast with little or no deviation. In other words, the jest stream creates a straight line.
ZONAL - Term applied to a straight, usually west to east and fast upper level wind flow.

It is often found in the vicinity of the jet stream where large shears in the horizonal and vertical are found, although this turbulence is not limited just to jet stream locale.
The accompanying zonal (east-west) component often is weaker than normal. Compare with zonal flow.
On many occasions, particularly in mid-latitude/temperate zone regions, the flow is directed more or less directly from west to east, crossing few latitude zones within the same longitude range: this is a 'highly zonal' type - any short-wave ...
