以影响我国近海船舶航行安全的典型寒潮天气过程为研究对象，运用WAVEWATCH海浪模式对包含选定航线的黄东海海域开展了海浪数值模拟研究，并应用波浪中船舶失速近似估算公式对船舶航行海域的失速分布进行数值计算，根据实船观测的船舶失速数据对计算结果进行验证，研究结果表明，WAVEWATCH能较好地模拟风浪的分布，在此基础上的船舶失速理论计算结果总体小于实船观测数据.

 The third generation wave model WAVEWATCH is applied to simulate the wind wave generated by cold wave in Yellow and East Sea, and then the distribution of ship speed loss is approximately calculated by using the simulated wave height, wave period, etc. The calculated speed loss is analyzed and validated by comparing with the observed speed loss on board. The results show that WAVEWATCH can preferably simulate and reflect the distribution of wind waves, and the calculated speed loss is totally less than the observed speed loss.
