On the parameterization of eddy transfer part I. Theory

摘要

This is the first of three linked papers which develop an eddy parameterization scheme for mean flows which are wide compared with a deformation radius. The scheme is partly based on the behavior of potential vorticity and thickness fluxes in linear instability, where the former are downgradient (apart from a turning matrix, not present in channel models) and the latter are not precisely downgradient, except on an f-plane.
