Snow cover is a key component of the global climate system, is crucial for the water supply of large parts of the world's population, and has economic importance e.g. for hydropower generation or in the winter tourism industry. We simulate the temporal and spatial evolution of the mountain snow and ice cover on regional scales, which requires solving for the energy and mass fluxes between the atmosphere, the snow cover and the ground. Accounting for small-scale topography-driven processes such as radiation fluxes from surrounding terrain or wind-driven or gravitational snow redistribution requires high resolution simulations, associated with large computational demands especially when performing operational ensemble forecasts or long-term climate change scenario simulations. As the current model version is only weakly parallelized, currently a reimplementation of the model is being initiated which should exploit state-of-the-art HPC methods.
