Mesoscale wind and wave field modeling in the area of the Odra Lagoon

The Odra lagoon is a small inner lagoon of the western Baltic Sea which is almost completely landlocked. The wind field in this area is influenced by the formation of atmospheric boundary layers, which generate highly inhomogeneous wind fields, which can be detected by means of in situ measurements and remote sensing techniques. Different numerical wind field estimation techniques were tested within the lagoon and validated against in situ measurements. The output of a coarse-grid standard model of the DWD (Deutscher Wetterdienst) for Europe, as well as a “nested-grid” model run of a mesoscale atmospheric model, was used to estimate the local wind field structure. Two data interpolation techniques employing a set of preprocessed wind fields, generated by the mesoscale atmospheric model, and in situ measurements at pile stations within the area gave best results regarding the reconstruction of the wind field variability in space and time. Subsequent model runs with a shallow-water wave model gave better hindcast results, while using these data interpolation technique wind fields as forcing.
