| 摘 要： | 基于1980—2019年数值模拟的水位和ERA5的风速数据，使用EOF分析方法，研究了渤黄东海40年的水位变化特征和动力机制，分析了气候变化和极端天气对水位变化产生的影响。EOF分析主要模态结果显示，东海东北部海域的水位变化受黑潮路径改变的影响比较明显，并存在一定的时间延迟；台湾岛东北部的水位变化受到黑潮入侵影响，与ENSO变化呈现一定相关性。研究区风速的EOF分析结果显示，年际变化受ENSO的影响显著，并影响了渤黄东海部分区域的水位变化。

| Abstract: | Based on the ERA5 wind speed data and numerical simulation of water level from 1980 to 2019, this paper uses the Empirical Orthogonal Function (EOF) analysis method to study the characteristics and dynamic mechanism of water level change over the past 40 years in the Bohai Sea, Yellow Sea, and the East China Sea, and analyzes the impact of climate change and extreme weather on water level change. The results show that the water level variation at the northeast part of the East China Sea was significantly affected by the Kuroshio path change and there was a time lag. The water level variation of sea on the northeast of Taiwan Island was affected by the Kuroshio invasion and was correlated with the El Ni?oSouthern Oscillation (ENSO). Significantly affected by ENSO, the interannual variation of wind speed influenced the water level variation at some areas in the Bohai Sea, Yellow Sea, and the East China Sea. |
