Operational NWP using ALADIN model in CMHS

The primary goal of the numerical weather prediction (NWP) section in Croatian Meteorological andHydrological Service (CMHS) is running and delivering the operational ALADIN (Aire Limitee Adaptation Dynamique developement InterNational) forecast products to a number of users on time twice a day, every day. The operational forecast is a time critical application limited by the time span between the availability of the input data (measurements and the large scale model data) and the time when the users want the forecast to be available. This is a serious limiting factor for the model configuration used for the operational forecast, model resolution and domain size determined by the computer hardware equipment and the data transfer network. The operational forecast products are grib files of the model data, pseudo-TEMPs, figures and tables. They are distributed automatically to the users that range from the forecast department, air traffic control, Ministry of Internal Affairs, Ministry of Defence, private companies, foreign institutions, TV and other media.
