Simulation and assessment of historical storm waves around Hainan Island
This study conducts a series of numerical simulations to reconstruct storm waves around Hainan Island during historical typhoon scenarios happened in the South China Sea.Based on the best path dataset of typhoons from 1959 to 2021 provided by the Tropical Cyclone Data Center of the China Meteorological Administration,an empirical wind mode combined with the reanalysis wind field data obtained from European Centre for Medium-Range Weather Forecasts(ECMWF)has been used to drive the third-generation wave model SWAN,which is used to simulate the wave process during each typhoon event.The numerical results are compared with the observed data during the Typhoon"Sarika"in 2016 and Typhoon"Chaba"in 2022,proving the good accuracy of the model.Totally 682 typhoon events have been simulated.Based on the simulation results,the spatial distribution of wave characteristics around Hainan Island has been provided.Furthermore,the wave height,wave direction and wave period along the coast of Hainan Island have been preliminary evaluated.
