Abstract: The Yellow Sea and the East China Sea, adjacent to Changjiang Estuary, have dense shipping routes and busy shipping. The extreme waves generated by tropical cyclone (TC) significantly threaten the navigation safety of ships. In this study, the wind dataset of the best tracks of TC affecting the Yellow Sea and the East China Sea from 1949 to 2022 was extracted, and the SWAN (Simulating WAves Nearshore) wave model was driven to obtain the wave data under the influence of TC, and the characteristics of the intensity, frequency and spatial distribution of historical typhoon waves were analyzed, and the asymmetric distribution characteristics of waves at different TC translation speeds and the main possible causes of dangerous waves were discussed. Results show that, under the influence of TC, the wave intensity and frequency in the study area show significant spatial differences, and the distributions of wave risk level decreased from southeast to northwest, and the dominant wave direction of extreme typhoon waves is mainly SE direction. In the area investigated, the offshore waters in the southeast belong to the high wave risk area, and the wave risk level in the offshore waters south of 30°N is relatively higher than that in the offshore waters north of 30°N. Typhoon waves show obvious asymmetric distributions, and the longer effective wave height in the right front quadrant brought about longer wavelengths and wave periods. At the same time, the asymmetry of wave field caused by the medium-speed moving TC with moving speed of 3.0～7.0 m/s is the most obvious.
