Disasters such as strong winds and huge waves caused by typhoons have a significant impact on the offshore area of Shandong peninsula.In this paper,by using the third-generation wave model SWAN,the driving field of the model was formed by ERA5 background wind field and the typhoon model wind field nested with Takahashi and Fujita.t formulas.The typhoon waves in the process of No.9 typhoon"LIKEMA"in 2019 were simulated.According to the simulation results,the distribu-tion of effective wave height,average period and wave age of typhoon wave was analyzed numerically,and the spatial distribution characteristics of typhoon wave during typhoon"LIKEMA"were prelimina-rily explored,which provided technical support for typhoon wave warning,disaster prevention and miti-gation in Shandong province.The research results have certain scientific significance and application value.
