The topic of our presentation is to show  characteristics of the wind for the  Polish coastal areas. In our presentation we show distribution  of wind speed and wind direction based on the COSMO (Consortium for Small-scale Modelling) model forecasts  at a mesh resolution of 2.8 km and their verification with 24 hour measurements for a five synoptic stations: Swinoujscie, Kolobrzeg, Ustka, Leba and Hel. The Polish Institute of Meteorology and Water Management – National Research Institute (IMWM-NRI) runs an operational model COSMO   using two nested domains at horizontal resolutions of 7 km and 2.8 km. The model produces 36 hour and 78 hour forecasts four times per day for 2.8 km and 7 km domain resolutions respectively. However, only the 00 UTC forecasts are  utilized in this study. We show wind analyzes at synoptic stations for different time scales (hours, days, months). We also analyze situations of extreme winds, such as for example passage of hurricane Alfrida in January 2019 on the Polish coast. The results show  characteristic distribution of wind speed and direction at the interface between sea and land . The wind is both destructive and conducive to human action. It causes local flooding, damage in ports, knocks down trees but also provides clean energy for wind farms or serves tourism activities as yachting or surfing.Poland plans recently to build an offshore wind farm in the Baltic Sea. Increasingly accurate wind forecasts are then one of the necessary elements for assessing the local climatology at the wind farm site and to further provide warnings and  decisive support to its operation. </p><p> </p><p> </p><p>Presentation preference: POSTER</p><p>EGU/2020/session 35921</p><p> </p><p>Institute of Meteorology and Water Management – National Research Institute</p><p>Podleśna 61</p><p>01-633 Warsaw</p><p>Poland</p>
