摘要
基于第三代海浪数值模式wAvEwATCH—III（v3．14），在CCMP风场驱动下，对2009年平常月份与台风“茉莉”作用期间涌浪场及混合浪场进行了数值模拟，探讨了东海E3海域的涌浪在不同气象条件下的产生机理及其演变特性。结果表明：平常月份东海E3海域的涌浪主要来自东海海域及西北太平洋海域，当涌浪来自东海海域，涌浪波高较大，涌浪波高多在0．7～2m，谱峰周期约为8～10s，混合浪中涌浪成分较高；当涌浪来自西北太平洋海域，涌浪的有效波高多在0．2～O．7m，谱峰周期约为8～lOs，混合浪中涌浪成分较小。台风期间，东海E3海域主要受西北太平洋海域传来的涌浪影响，涌浪的有效波高及谱峰周期都较平常月份为大，有效波高主要分布在0．5～1．8m，谱峰周期主要分布在10～18s。
Based on the third generation numerical wave model WAVEWATCH-III（v 3.14）, numerical simulation of swell field and mixed wave field driven by CCMP wind field are performed in the case of ordinary months as well as the action period of Typhoon Melor. The mechanism of production of the swell in the E3 sea area of the East China Sea and its evolution characteristics are investigated in differ- ent weather conditions. Results indicate that the swell in the E3 sea area is mainly from the East China Sea and the Northwest Pacific Ocean during the ordinary months. By the time the swell coming from the former sea area, the height is relatively larger （0.2-0.7m） with spectral peak period around 8-10s while swell is the major components of the mixed wave. For the case that the swell coming from the lat- ter area, its significant wave height is about 0.2 0. 7m with spectral peak period around 8-10s while swell is the minor components. During the period of typhoon, the E3 sea area is influenced by the swell propagating from the Northwest Pacific Ocean, with larger significant wave height and spectral peak period of 0.5-1.8m and 10-18s respectively, compared with the ordinary month situation.
