Contrast Analysis on Numerical Simulation of 0703 Cyclone Strong Storm Surge

The coastal high water levels in Bohai Sea and the north of Yellow Sea result in a storm surge disaster onMar 4—5, 2007.The severe storm surge disaster is caused by the surface cyclone.Using T213 and NCEP data(1000 hPa wind and the surface pressure)by Hamburg Shelf Ocean Model, 0703 cyclone storm surge in BohaiSea and the north of Yellow Sea is simulated to investigate the process of storm surge set-up.The model is testedwith observations of Yantai and Weihai.The results show that the agreements between calculation and observation storm surge set-up of Yantai and Weihai are good, and the period of storm surge set-up in Bohai Sea and thenorth of Yellow Sea is well simulated.The numerical simulated results are in better agreement with observationsusing T213 than NCEP data.It indicates that it is feasible to study and simulate cyclone storm surge in BohaiSea and the north of Yellow Sea by Hamburg Shelf Ocean Model.
