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海、东海海域开展海浪数值模拟研究，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。结果表明， WAVEWATCH 能较好地模拟风浪分布，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。

Taking the typical cold weather process which im-pacted on offshore vessel navigation safety as research object , the third generation wave model WAVEWATCH was applied to simulate the wind wave generated by cold wave in Yellow and East Sea containing the selected route , and then the dis-tribution of ship speed loss was approximately calculated by u-sing approximate estimation formula for ship speed loss in wave.The calculated speed loss is analyzed and validated by comparing with the observed speed loss on board , and results show that WAVEWATCH can simulate and reflect the distri-bution of wind waves better , and the calculated speed loss is totally less than the observed one .
