On August 9, 1988, Beaufort 3 (weak breeze) was measured in the central North
Sea, Beaufort 2 in the Southern Bight and Beaufort 1 in the German Bight. The
near bed (1 m above bed) current velocities, calculated by the water circulation
model (Pohlmann 1996), are shown in Fig. 4. The currents are generated by dennear bed current velocity
