基于1965年9月和1966年3月在台湾以东黑潮海区两个航次的CSK水文调查资料,采用β螺线方法对调查海区进行流速计算.首先,对方法进行研讨.其次,对台湾以东黑潮流域进行流速计算,其结果表明:(1)在台湾以东,黑潮存在着季节变化;(2)深层流有一些重要特征,例如,对两个航次的计算都揭示了台湾东岸附近位于苏澳—与那国岛海脊以南的逆流;1965年9月在深层1200—1500m存在一个气旋式涡,并且,该涡与深层的冷水团有很好的对应. Based on the CSK hydrographic survey data of two voyages in the Kuroshio waters east of Taiwan from September 1965 to March 1966 and using the β-helix method to calculate the velocity of the surveyed sea area, firstly, the method was discussed.Secondly, The results show that: (1) There is a seasonal variation of the Kuroshio in the east of Taiwan; (2) There are some important characteristics of the Kuroshio current. For example, the calculation of the two voyages revealed that the east of Taiwan There is a cyclonic vortex at depth 1200-1500m in September 1965, and the vortex has good correspondence with the deep cold water mass.
