Abstract：In this paper,the high-order spectral model HOS was used to simulate the waves in the northern South China Sea.First,the wave model WAVEWATCH Ⅲ was used to simulate the waves in the target sea area,extracted the two-dimensional wave spectrum of the extreme process,and used it as an open boundary condition to simulate the wave surface time series of 12 typhoons in the northern South China Sea under extreme wave conditions.Through the processing and analysis of the wave sur-face time series,it was concluded that the waves in the target sea area were strongly nonlinear,and ab-normal waves appeared at some measuring points.
