通过综合卫星高度计和浮标资料得到的海面速度场的局部最强部分，从1992年10月到2000年12月每10天提取一次日本以南的黑潮轴线。所得到的轴线清楚地表达了海底地形的影响；当黑潮越过伊豆海脊时，观察到了三个振型。轴线非常稳定，位于Kii海峡附近的Tosa-Bae以南。黑潮轴线的平均流速由九州以南的0.65m/S逐渐增大到恩州附近的1.45m/S。
By tracking the locally strongest part of the sea-surface velocity field, which was obtained by integrating data of satellite altimeters and surface drifting buoys, we extracted the Kuroshio axis south of Japan every 10 days from October 1992 to December 2000. The obtained axes clearly express the effect of the bottom topography; three modes were observed when the Kuroshio ran over the Izu Ridge. The axis was very stable to the south of 'Tosa-bae,' off the Kii Channel. Mean current speed at the Kuroshio axis gradually increased from 0.65 m/s south of Kyushu to 1.45 m/s off Enshu-nada.
