英文摘要	Storm surge impact depends on coastal geographical and bathymetric features as well as various tropical cyclone characteristics including the size, intensity, and impact angle of the storm. Although the factors contributing to storm surge are well studied, uncertainties remain regarding the level of sensitivity to these parameters. This work seeks to contribute to the current knowledge of storm surge by studying the sensitivity to tropical cyclone landfall angle. We perform an ensemble of synthetic tropical cyclones using a newly developed modeling capability derived from the Weather Research and Forecasting (WRF) model, the Hybrid WRF Cyclone Model. Wind and atmospheric pressure field outputs from 200 synthetic cyclones are used as atmospheric forcing for the Advance Circulation (ADCIRC) model. We study the sensitivity of storm surge offshore extent and inundation to tropical cyclone impact angle. The extent of the impact area around the landfall location is sensitive to the cyclone landfall angle. Cyclones with tracks perpendicular to the coast are shown to produce the highest water levels and broadest inland and offshore extent. Results also indicate a heterogeneity in the sensitivity to landfall angle along the coast, highlighting the importance of both cyclone impact angle and location. ©2020. American Geophysical Union.
