The relationship between zonal mean flow and quasi-stationary waves in the mid troposphere.

Abstract

The degree to which quasi-stationary midtropospheric flow is consistent with linear, potential vorticity conservation is investigated. The linear theory suggests there should be a well defined relationship between the zonal mean component of steady flow and departures from the zonal mean. A set of 45 monthly mean winter states is examined to determine if there is a zonal/eddy relationship. -from Author
