台风风浪的研究对航海、港口、近海及近岸工程都有重要影响。最大风半径的计算采用经验公式法或大风周期反演法，并将由Jelesnianski2风公式和藤田气压公式导出的参数台风风模式、台风气压公式和第三代深海波浪模式(WaveWatchⅢ)应用于台风Winnie引发的风暴波后播。模拟结果与观测资料的对比表明：台风Winnie期间，MEF模拟的西北太平洋风暴波分布较为合理。将三个近海观测站的有效波高与实测值进行了比较，误差在10%左右，结果表明MEF优于MGCR。因此，由复合风场和WaveWatchⅢ得到的模拟结果可以为造船、海洋工程和海岸工程提供科学参考。
The research of stormy waves caused by typhoon has significant impact on navigation,harbor,offshore and nearshore engineering. The radius of maximum winds is calculated by method of experiential formula(MEF)or method of gale cycle retrieval (MGCR),and the parameter typhoon wind model(PTWM),which is derived from Jelesnianski2 wind formula and Fujita pressure formula(FPF),FPF and the third-generation deep-sea wave model(WAVEWATCH Ⅲ) are applied to the storm wave hindcast induced by the typhoon Winnie. The comparisons between the simulation results and observation data indicate that:during the typhoon Winnie,the distribution of modeled storm-waves in Northwest Pacific Ocean,which is simulated by MEF,is more reasonable. Comparing the significant wave heights calculated and measured in three offshore stations,the error is about 10%,and it was shown that MEF is better than MGCR. So the modeled results,which are derived from the compound wind field and WAVEWATCH Ⅲ,can serve for scientific reference of naval architecture,ocean engineering,and coastal engi-neering.
