Sažetak
Numerical weather prediction models will in the near future be operationally run at resolutions of the order of l-3km even at the Alpine scale. It is the purpose of this study to investigate the potential benefits and also the problems involved with this increase in resolution. To this end high resolution simulations (at 2km) with the Lokal Model] (LM) of the COSMO1 are performed for selected MAP IOP cases and the results are examined in comparison with available high resolution datasets from the MAP campaign and with operational simulations at coarser resolution. The study develops in three directions: (i) study of meso-scale structures with help of a new modeling tool (Dynamics), (ii) with a systematical analysis of the model behavior for a selection of MAP IOP case studies with particular attention to model errors in precipitation field (Prediction) and (iii) experiments with the numerical set-up of the model (Numerics) investigating the influence of the domain size on the high resolution simulation and adapting the number of vertical levels of the model due to the increased horizontal resolution.
