Based on the FVCOM three-dimensional finite volume ocean model,combined with the Jelesnianski empirical wind field model and ECWMF background wind field superimposition to form a synthetic wind field,the hydrodynamic characteristics of the Liaoning coast of the North Yellow Sea during the transit of Typhoon"Rumbiya"were studied,and the influence of different typhoon parameters such as typhoon track,moving speed,maximum wind radius,central pressure,and maximum wind speed on storm surge in the Northern Yellow Sea was analyzed.The results show that,the extreme storm surges decreases with the westward shift of typhoon track in the study area.With the increase of typhoon moving speed,the extreme storm surges reduces,and the duration of high water level decreases significantly.The extreme storm surges and the duration of high water level increases with the increase of the radius of maximum wind speed.The extreme value of storm surge is positively correlated with the maximum wind speed,and the change of the maximum wind speed has no obvious effect on the duration of high water.The storm surge increases as the central pressure decreases.The study results can provide some reference for storm surge disaster protection along the Liaoning coast of the North Yellow Sea.
