摘要
利用1996年6月28日至7月29日在位于渤海中部一点 (38°19′39.426″N ,119°37′01.546″E)获得的潮流调查资料 ,进行了一个月的实测潮流资料调和分析 ,计算了该站北、东分量各74个分潮的调和常数 ,进而计算各分量的潮流椭圆要素 ,给出了10个主要分潮的潮流调和常数及其椭圆要素。对实测潮流资料进行了频率统计 ,给出了流速、流向的频率分布。有助于进一步了解该海区的潮流性质并为数值模拟者研究渤海的潮流提供了验证数据。
Using one months (1996.6.28～7.29) current data observed in middle of Bohai Sea(38°19′39.426″N,119°37 ′01.546 ″E), this paper carried out the harmonic analysis. The harmonic constants in North and East of 74 tidal components are calculated. Tidal current elliptic factors are then computed too. The harmonic constants and elliptic factors of 10 main tidal components of current are given in this paper. Based on frequency statistic, the frequency distribution of observed current data are given. These results must be helpful to further understanding tidal current characters in the sea area. Also validation data are provided for modeller study on tidal current in Bohai Sea.
