中文摘要：基于海浪浮标观测数据与ADCIRC-SWAN波流耦合模型,分析了2023年2304号台风“泰利”过境期间南海北部湾区域海浪特征,以及不同要素对有效波高的影响。研究结果显示:“泰利”过境期间测站有效波高峰值为2.73 m,波周期为6~9 s,海浪以东向传播为主;北部湾内有效波高最大可达3.7 m,高值主要分布于北部湾东侧靠近雷州半岛与琼州海峡海域。过境前,北部湾东侧涌浪为主,而过境后则主要受风浪控制。近岸有效波高在水深15 m以上区域主要受白冠效应、底摩擦、涌浪与四波相互作用影响,随着水深降低至5 m,波浪破碎与三波相互作用快速增强,致使有效波高快速降低。耦合实验显示,底摩擦主要影响北部湾水深20 m以内的浅水区域,水位耦合对有效波高的影响主要集中于北部湾北部与东部近岸区域,而流速耦合的影响主要集中于琼州海峡与远离近岸的北部湾内水域,潮流的周期变化对海峡内有效波高的调制作用更强,能在12 h内使琼州海峡内有效波高最大减弱近0.6 m。

外文摘要：Based on wave buoy observation and the ADCIRC-SWAN wave-current coupled model,this study analyzes the wave characteristics in the Beibu Gulf of the South China Sea during typhoon“TALIM”(No.2304 in 2023)and assesses the impact of tidal current on effective wave height.It shows that during“TALIM”,the maximum observed significant wave height was 2.73 m with wave period of 6-9 seconds,and the waves primarily propagated eastward.The maximum significant wave height in the Beibu Gulf reached 3.7 m with high effective wave height being distributed mainly in the eastern Beibu Gulf near the Leizhou Peninsula and the Qiongzhou Strait.Before“TALIM”arrived,there was a region dominated by swell waves in the east of the Beibu Gulf,while after“TALIM”passed,the region was mainly controlled by wind waves.In areas deeper than 15 m,the significant wave height nearshore was largely affected by whitecapping,bottom friction,swells,and the interactions between these factors.As water depth decreased to 5 meters,wave breaking and triad interactions caused a rapid reduction in significant wave height.Coupling experiments show that bottom friction primarily affects shallow areas within 20 meters of water depth in the Beibu Gulf,the impact of water level is mainly in nearshore areas of the northern and eastern Beibu Gulf,and the impact of current coupling is primarily in the Qiongzhou Strait and areas farther from coast.It also shows that tidal current has a stronger effect on the significant wave height within the strait,it can significantly reduce the significant wave height in the Qiongzhou Strait by nearly 0.6 m within 12 hours.
