摘要：

利用实测资料对比和FVCOM数值模拟等方法，研究了“利奇马”台风风暴潮在渤海的演变规律。研究表明：渤海沿岸的风暴潮过程是由局地风“直接作用”及外部天气系统“间接影响”共同作用引起的，且它们引起的风暴潮时空分布明显不同。在“利奇马”台风风暴潮中，“直接作用”引起的风暴增水在渤海湾和莱州湾沿岸分别约占总风暴增水的2/3和1/2。

In this paper, the evolution mechanism of the storm surge caused by typhoon "Likima" in the Bohai Sea is studied based on the in-situ observation data and FVCOM. The results show that the storm surge in the Bohai Sea is jointly caused by direct-effect of local wind and indirect-effect of the marginal weather system with different spatial and temporal distribution. For the storm surge caused by typhoon "Lekima", the direct-effect accounts for 2/3 and 1/2 of the total storm surge in the Bohai Bay and Laizhou Bay, respectively.
