Using the grid infrastructure in weather prediction: the WRF-ARW model

In this work the application of the Advanced Weather Research and Forecasting (WRF-ARW) model on the Grid infrastructure will be presented. Using WRF-ARW model and Grid infrastructure is very important to achieve a good weather forecast for small and large regions, but also it´s better to understand how weather behaves in very complex situation or weather conditions. These conditions can be more complicated and depend on local terrain, for example “Foehn effect” and local extreme situation, like as thunderstorm in Banja Luka has occurred last summer. The weather forecast is often very complicated and often mistaken due to local terrain conditions or global synoptic situation.
