Summary:

As part of PROZA project at the Institute of Oceanography, University of Gdańsk, work is being carried out on launching an integrated wave-current model for the Baltic Sea region. Wave WAM and current POM models used for this pur-pose, are supplied with data from numerical weather forecasts from the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) model operating at ICM. The accuracy of forecasts of meteorological parameters directly impacts the forecasts of wind wave and sea current fields. The accuracy of results of short term weather forecasts generated by COAMPS and Unified Model (UMPL) operating at ICM, was assessed for two locations on the coast of Baltic Sea in Poland. For the two studied locations (Łeba and Hel), air temperature is forecasted with highest accuracy (r>90%), and wind direction and velocity forecasts are characterized by lower accuracy (r<85%)
