A third-generation spectral model has been developed to simulate typhoon-generated waves in South China sea near Hong Kong. The model solves the energy conservation equation of the two dimensional wave spectrum, and directly computes the non-linear energy interaction among waves of different frequencies to avoid the imposition of restriction on the spectral shape of the predicted spectra. The model uses semi-implicit scheme for the source terms and a special treatment on the high frequency tail of the spectrum so that large time integration step can be employed to enhance computational efficiency. The simulation results are satisfactory as compared with the field measurements.
