STATISTICS OF EXTREME WINDS; STORM SURGES AND OCEAN WAVES
The evolution of storm surge statistics along the North Sea coasts during the past 50 to 100 years is reconstructed using statistical and dynamical models with and without data assimilation. It turns out that the mean water level has increased since the 1960s by a few centimeters along the southern and eastern coast lines, but that the variations relative to the annual mean have undergone hardly any changes. This sea level rise is reflecting the tendency of the last decades for more frequent westerly wind conditions, which is not only associated with higher water levels in the southeast of the North Sea, but also with increased wave energy reaching the eastern shoreline as well as higher waves in the German Bight.
Scenarions of possible future changes are presented as well.
Hans von Storch er i perioden 6. oktober til 10.oktober Velux-gæsteforsker ved Geofysisk Afdeling/COGCI.
