| 摘要：以浙江中部三门湾海域为重点研究区域，基于MIKE21 SW模型模拟了6个台风波浪过程，分析了不同路径台风影响下三门湾海域内有效波高和波浪谱情况。研究表明，三门湾海域在台风影响下有效波高和风速呈现出较为一致的变化趋势，台风“麦莎”期间研究海域内最大有效波高超过2 m；该海域受台风影响最大期间，波浪能量的分布范围为NE~SE向；登陆型台风“麦莎”和登陆后转向型台风“罗莎”的波能谱是以风浪为主的单峰谱。转向型台风“蔷薇”、“泰利”的波能谱以双峰为主，波浪是由涌浪和风浪组成的混合浪，其中涌浪占比成分较大。外海登陆型台风“海马”的波能谱是以风浪为主的单峰谱，同时伴随有少量涌浪。外海转向型台风“潭美”的波能谱是以涌浪为主的单峰谱。 |

| Abstract: Based on MIKE21 SW model, six typhoon wave processes are simulated in the Sanmen Bay area in central Zhejiang Province, and the significant wave height and wave spectrum in the Sanmen Bay area under the influence of typhoons in different paths are analyzed. The research shows that under the influence of typhoon, the significant wave height and wind speed in the sea area of Sanmen Bay show a relatively consistent change trend, and the maximum significant wave height in the study sea area during typhoon Matsa exceeds 2 m. During the period when the sea area is most affected by typhoon, the distribution range of wave energy is NE~SE. The wave energy spectrum of landing typhoon Matsa and turning after landing typhoon Krosa is single-peaked dominated by wind waves. The wave energy spectrum of turning typhoon Jangmi and Talim is double-peaked, and the wave is a combination of swell and wind sea, the swell is in a dominant position. The wave energy spectrum of open sea landing typhoon Haima is single-peaked dominated by wind waves, accompanied by a small amount of swell. The wave energy spectrum of open sea turning typhoon Trami is single-peaked dominated by swell. |
