Enforcing the continuity equation in numerical models of geophysical fluid flows

摘要: A method is described for modifying the velocity field in geophysical fluid models so as to enforce continuity equation. corrective mass flux introduced, which derives from a scalar potential. The latter solution of Poisson problem formulated such way that suitable norm be minimum. It seen generalised vertical coordinate may used. Finally, an elementary, one-dimensional illustration functioning suggested provided. (C) 2001 Elsevier Science Ltd. All rights reserved.
