摘要：

利用實測資料對比和FVCOM數(shù)值模擬等方法，研究了“利奇馬”臺風風暴潮在渤海的演變規(guī)律。研究表明：渤海沿岸的風暴潮過程是由局地風“直接作用”及外部天氣系統(tǒng)“間接影響”共同作用引起的，且它們引起的風暴潮時空分布明顯不同。在“利奇馬”臺風風暴潮中，“直接作用”引起的風暴增水在渤海灣和萊州灣沿岸分別約占總風暴增水的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.
