A Multilayer Hydrodynamical-Numerical Model (W. Hansen Type): Model Description and Operating/Running Instructions. Part 2.

Abstract

The multilayer Hydrodynamical-Numerical (HN) model (W. Hansen type) is, in many respects, similar to Hansen's single-layer HN model. The hydrodynamical formulas present vertically integrated motion through given layers. The lower layer is partly driven by friction, which is proportional to the mean density relations of the layers, and partly by horizontal pressure gradients caused by the inclination of the surface as well as of the interface. The finite difference forms are similar to those used in single-layer models, except for the additional terms dictated by the second layer. The model uses a continuity equation in its direct, physically simple and correct form. Besides the basic formulas of the model, this report describes the numerical model in FORTRAN. The description of the input parameters, abbreviations used, and the program itself are given in the Appendixes. (Modified author abstract)
