  • Another reason why simple discretizations of rotated diffusion operators cause problems in oceans models: comments on "Isoneutral Diffusion in a z-Coordinate Ocean Model"

Abstract

In recent papers, (Grifies et al. 1998; Griffies 1998). the problem of isopycnal diffusion and Gent-Mc Williams Stirring in z-codordinate models was reviewed and a new discretization proposed. It was shown that classical discretization (Cox 1987; Gent and Mc Williams 1990) needs rather heavy background diffusion along the grid lines in order to stabilize the scheme. Griffies et al.(1998) show the possible origin of the problem.
