摘要
本文根据渤海近百观测点单周日潮流资料,采用单周日潮流的准调和分析方法计算了M2分潮流调和常数,进而计算了M2分潮流椭圆要素,探讨了M2分潮流旋转方向在渤海的分布及随深度的变化状况。分析结果经过与三维数值模拟结果对比分析,拟合良好。
In this paper,based on the tidal current data of a day observed from about 100 observation points of Bohai Sea,the harmonic constants of M2 tidal current are calculated using the method of quasi - harmonic a- nalysis. Tidal current elliptic factors are then computed too. The results indicate the distribution and the varia- tion characteristics with depth of M2 tidal current rotating direction in the Bohai Sea. Both results of numerical modeling and harmonic analysis agree well.
