中文摘要：

黄海是典型的强潮驱动的陆架浅海。为了研究黄海对台风的响应特点,本文利用区域海洋模式（Regional Ocean Modeling Systems,ROMS）分别模拟了在有潮和无潮作用下黄海对台风＂布拉万＂的响应过程。结果表明,不管潮存在与否,＂布拉万＂经过黄海后都引起了海表面降温和流速的近惯性振荡响应,这种响应主要分布于黄海中部较深区域,带通滤波提取的近惯性流速具有垂向第一模态特征。同时,研究发现强背景潮流能显著地影响黄海对＂布拉万＂的响应过程。主要结论如下：一方面,由于潮的存在,近岸垂向混合均匀的较暖水体与远岸较冷水体之间会形成潮混合温度锋面,＂布拉万＂过后,暖水发生了明显的离岸扩张,尽管路径右侧的混合层降温更显著,但是左侧即黄海西岸的暖水扩张更明显;另一方面,潮的存在减弱了布拉万产生的近惯性振荡响应,半日潮流在黄海仍然占据主导地位。在混合层中潮流的作用减弱了＂布拉万＂产生的近惯性能量,但也使其更易穿过跃层传入黄海内部。

英文摘要：

The Yellow Sea is a tidal energetic continental shelf sea, in order to investigate the characteristics of the Yellow Sea to the typhoons, the responses to the typhoon Bolaven are simulated with Regional Ocean Modeling Systems（ROMS） with and without tidal forcing, respectively. The results indicate that no matter whether there is tidal forcing, the drop of the sea surface temperature and the near inertial oscillations are well simulated. We find that the near inertial velocities are characterized by a first baroclinic mode vertically. At the same time, the near inertial responses to Bolaven are mainly distributed in the central areas of the Yellow Sea from the distributions of the depth-time averaged near inertial energy. We conclude that the strong background tidal currents could obviously affect the ocean responses to Bolaven： because of the tides, a tidal induced temperature front could be developed between the warmer water near the shore and the colder water off the shore. After Bolaven, the warmer water expands offshore, although the upper mixed layer temperature drop is significant right to the track, it is much more obvious of the near shore warmer water expansion west of the Yellow Sea. On the other hand, the near inertial responses are weakened because of the tides, and the semidiurnal currents are still prominent. The near inertial energy in the upper mixed layer is decreased because of the tides; however, the part that penetrating the thermocline propagating into the ocean interior is increased.
