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. The scheme leads to a diffusivity which varies quite strongly with depth and is smallest at surface and floor. Intrinsic delta-function fluxes also occur at surface and floor, and these are worked out in detail. It is shown that all such parameterization schemes (whether linked to linear instability or not) must satisfy a necessary consistency condition, in the form of a vertical integral. A uniform diffusivity does not satisfy this requirement unless it is defined to vanish at surface and floor. Two methods to compute approximate diffusivities efficiently are given, and their results compare well with exact results from instability theory.

More about this publication?
  • The Journal of Marine Research, one of the oldest journals in American marine science, publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. Biological studies involving coupling between ecological and physical processes are preferred over those that report systematics. The editors strive always to serve authors and readers in the academic oceanographic community by publishing papers vital to the marine research in the long and rich tradition of the Sears Foundation for Marine Research. We welcome you to the Journal of Marine Research.
