Summary
Two-dimensional numerical simulations of sea breeze development over a large sandbar on the North Sea coast of Germany are reported. The numerical model used in these experiments contains a detailed treatment of soil moisture, which allows evaluation of the effects of differential surface characteristics on the airflow pattern. Results of the simulations indicate that the contrast between the moist sandbar and adjacent dry land, the tidal inundation of the sandbar, and the westward penetration of the Baltic sea breeze play important roles in the development of mesoscale airflow patterns in the sandbar region.
Zusammenfassung
Die zweidimensionale, numerische Simulierung der Seebrisenentwicklung über einer großen Sandbank an der Nordseeküste Deutschlands wird beschrieben. Das hier angewandte Modell enthält eine detaillierte Behandlung der Bodenfeuchte, welche eine Auswertung des Effektes differenzierter Oberflächencharakteristika auf die Luftströmung erlaubt. Rechnungsresultate zeigen, daß der Kontrast zwischen Sandbank und benachbartem, trockenem Land, die gezeitenbewirkte Überflutung der Sandbank und die nach Osten vorrückende Seebrise der Ostsee eine wichtige Rolle in der Entwicklung von mesoskalaren Strömungsverteilungen im Gebiet der Sandbank spielen.
