Abstract:Damrey typhoon is the strongest typhoon landing the norther area of the Yangtze River since the founding of new China.Applying the Jelesnianski typhoon parameter model,MIKE-SW wave model and MIKE-FM hydrodynamic model,we study the waves and storm surge distribution characteristics when the typhoon landed in Jiangsu.Calculation results show that the typhoon parameter model and the wave model verify well,and can provide the accurate dynamic condition for the storm surge simulation.During the typhoon transit,the maximum wind speed is more than 40 ms in Lianyungang sea area and the sea level rise obviously.Near the typhoon center,the biggest storm tide is 1.7~1.8 m and the storm tide is 0.6~0.7 m at the high water level.The simulation system can accurately simulate the storm surge process during the typhoon period in Lianyungang sea area,and it is of significant value in prevention and mitigation of the typhoon disaster.
