Sažetak
For essentially historical reasons, the development of geophysical models has been done in separate independent directions: atmosphere, circulation, waves and others. As it happens, the boundary between such domains is especially important for correct geophysical modelling. We will explain how such coupling can be effectively achieved. This will cover the technical part of it, i.e. the construction of coupling libraries, how they are interfaced and how they communicate. We will explain our Parallel Geophysical Model Coupling Library (PGMCL) that achieves that. We will also cover the parallelization aspects of such coupled models. We will first consider the coupling of circulation and wave models via the coupling Ardhuin and the simplified Bennis formulation of wave coupling. We will show the effect of coupling on the circulation models and on the wave models. We will also consider the numerical aspects of the coupling. Finally, we will consider the effect of coupling of waves and atmosphere models. Here, the all important aspect is the modelling of the Charnock coefficient which is the key to the computation of the surface stress which is a major unknown in geophysical modelling.
