摘　　要：台风引起的大风浪和涌浪对船舶航行、抗台和避风有着重要的影响,为航海者提供实时、准确的海浪场对船舶的航行安全和营运效率有着重要的现实意义。选用一个对我国近海船舶航行造成较大影响的9711号台风Winnie为研究对象,应用国际上先进的海浪预报模型WAVEWATCH -Ⅲ对Winnie的海浪场进行了后报,将预报的有效波高与TOPEX Poseidon卫星高度计资料作了详细的对比分析,结果表明,预报的有效波高与卫星高度计资料基本一致,达到了航海活动所需的精度,从而为近海船舶航行提供科学的参考依据。The stormy waves and swells induced by typhoon have significant influence on navigation. Provided real-time and precise wave field has practical meanings to navigation safety and shipping efficiency. The Typhoon 9711 Winnie which had affected offshore navigation greatly is chosen as an object to be researched in this paper, and the advanced operational ocean wave forecast model, WAVEWATCH-Ⅲ is used to check the wave fields. The predicted significant wave heights(SWHs) are compared with the TOPEX/Poseidon(T/P) altimeter data in details. The results indicate that the predicted SWHs are basically consistent with the T/P altimeter data and reach the precision for navigation so as to be regarded as a scientific reference for offshore navigation.
