Cuxhaven for the year 2008. 
3.1.2 Baltic Sea 
In the Baltic Sea, water level variations are caused mainly by wind effects and seiches, 
whereas die tidal signal is relatively small, so that water level predictions for the Baltic 
differ markedly from those for die Nordi Sea. Therefore, die direct model-water level 
output is validated here. As it can be seen from the examples presented in Fig. 6, in which 
the results at station Warnemuende are shown, die model describes bodi die absolute 
water level elevation and the variability of it rather good.

Figure 6: Water level time series during two storm events in 2008 at Warnemuende station. Ob 
servations are shown in black, BSH-HBM data in blue. 
Tab. 3 indicates that the results at Warnemuende are representative for all German sta 
tions where correlations of about 90 % and RMSDs of about 10 cm are to be found. 
Moreover the simulated standard deviation equals nearly the observed one in all places.
