A high-resolution storm surge model encompassing the Bohai Sea,Yellow Sea,and East China Sea is developed based on the Finite Volume Community Ocean Model(FVCOM)to simulate and hindcast the storm sur-ges induced by Typhoon Chan-hom.The model's surge predictions align closely with observed tidal gauge data.Based on the International Best Track Archive for Climate Stewardship(IBTrACS)datasets,a linear regression is established between typhoons'maximum wind speeds and their minimum central pressures along China's coast,a-chieving a correlation coefficient of 0.96.On this basis,a variety of hypothetical typhoon paths are constructed based on the maximum wind intensity model to calculate the possible maximum storm surges(PMSS)in the Hang-zhou Bay and Zhoushan Archipelago.Our findings indicate that typhoons landing perpendicular to the coastline yield the highest surge elevations,peaking at 8.76 m in Hangzhou Bay and 2.62 m in the Zhoushan Archipelago.This re-search offers valuable insights for the risk assessment and disaster prevention and mitigation for marine engineering projects in the Hangzhou Bay and Zhoushan Archipelago areas.
