山东半岛沿岸的大振幅假潮

On the Large-amplitude Seiches along the Coasts of Shandong Peninsula

根据山东半岛沿岸１２ 个验潮站的水位资料曲线，摘取了各站的假潮参数（周期、振幅、延时和峰值出现时刻），并对该区域沿岸大振幅假潮变化做了统计分析，给出了假潮的基本特征——发生频率、月出现率、振动周期、延时和峰值出现的时刻；分析了假潮周期的谱型，最后还讨论了大振幅假潮形成的初步原因。

The Seiche parameters (period, amplitude, occurrence duration and occurrence time of the peak) were selected according to the water level data curves obtained at 12 tide gauge stations along the coasts of the Shandong Peninsula. The statistical analysis was made on the changes of the large amplitude seiche. Basic characteristics of seiches, such as frequency of occurrence, monthly occurrences, oscillation period, occurrence duration and occurrence time of the peak were given in this paper, as well as the analysis of the spectral types of the period of seiche. Finally the prime causes of the formation of the large amplitude seiche were discussed.$$$$
