Abstract

In this paper the application of the non-hydrostatic mesoscale model GRAMM to a mountinous region in the Alps is described. The simulation is used for the estimation of the pollution dispersion of a cellulose plant during selected weather conditions. The GRAMM model solves the conservation equations for mass, momentum, potential temperature and humidity in a terrain-following grid. The time integration scheme is explizit depending on two time levels ac- cording to Adams-Bashforth. The discretisation of the model makes use of the Gaussian and the first Green integral theorem without any co-ordinate trans- formation. The lateral boundary conditions are generalised radiation boundary conditi
