摘　　要：选取海州湾和大亚湾作为假潮研究区域,从研究区域两个验潮站的原始验潮记录曲线中分离出天文潮,得到时间间隔为1min的含有假潮振动的剩余值,进而统计分析了假潮的季节分布特征,并采用假潮与对应天气系统对比分析的方法,研究了假潮的成因.研究结果对海洋工程设计和风暴潮预报有重要的参考价值.The Haizhou bay and Daya bay are selected as basins for seiche research in this paper. By reducing astronomical tide, we get residuals which include seiches from original observed tide curve of two representational gauges of Haizhou bay and Daya bay. The time resolution of them is one minute. We have generally known the heights, frequency and seasonal distribution of seiches in the research basins. Corresponding to typical seiche processes, weather systems are analyzed carefully. We study primarily the causes of seiches in the two basins. The results have important value for the design of oceanic engineering and forecast of storm surges.
