circulation index

A measure of the magnitude of one of several aspects of large-scale atmospheric circulation patterns.

Indices most frequently measured represent the strength of the zonal (east–west) or meridional (north–south) components of the wind, at the surface or at the upper levels, usually averaged spatially and often averaged in time.
See meridional index, zonal index.
