A convergence study of two ocean models applied to a density driven flow
Authors:Helge Avlesen  Jarle Berntsen  Terje O Espelid
Abstract:A three‐dimensional, baroclinic and rotational benchmark for hydrostatic coastal ocean models is suggested. The computational domain is a quadratic basin 200×200 km horizontally and 200 m deep. The lateral boundaries are closed. Solutions to the problems are estimated with two different sigma co‐ordinate models, both for the diagnostic and the prognostic case. Grid‐ and time‐converged results are presented. For the transports, convergence within two significant digits is reported. Copyright © 2001 John Wiley & Sons, Ltd.
