结合Argos漂流浮标和TOPEX/Poseidon高度计资料，建立了黑潮及其邻区海面速度场的时间序列。在速度场的基础上，研究了吕宋海峡至托卡拉海峡Kc的变化。结果表明，KC不同区段的主要变化周期不同：吕宋海峡附近和台湾岛以东的KC的主要周期为季节内时间尺度，东海大陆架的KC是最稳定的，没有明显的周期性，而托卡拉海峡表现出季节变化的周期。这种不同的周期是由海洋内部传播的Rossby波引起的，岛链地形和局地风应力的调整。
By combining Argos drifter buoys and TOPEX/POSEIDON altimeter data, the time series of sea-surface velocity fields in the Kuroshio Current (KC) and adjacent regions are established. And the variability of the KC from the Luzon Strait to the Tokara Strait is studied based on the velocity fields. The results show that the dominant variability period varies in different segments of the KC: The primary period near the Luzon Strait and to the east of Taiwan Island is the intra-seasonal time scale; the KC on the continental shelf of the ECS is the steadiest segment without obvious periodicity, while the Tokara Strait shows the period of seasonal variability. The diverse periods are caused by the Rossby waves propagating from the interior ocean, with adjustments in topography of island chain and local wind stress.
