simulations described earlier, this simulation was carried out taking into account the 
meteorological forcing (atmospheric pressure and wind stress) of the extreme storm surge 
and the tide. 
At Wick, close to the northern model boundary, there is an almost linear superposition of the 
tsunami signal and the storm surge signal (Fig. 7.5.2). The increase of the peak water levels 
at Cuxhaven is lower than the simple signal (Fig. 7.5.3). At Borkum, however, the simulated 
peak water level almost corresponds to linear superposition (Fig. 7.5.4).
