利用1993-2008年的卫星测高资料，研究了黑潮路径与黑潮延伸区之间的关系。当黑潮采取近岸非大弯曲路径或典型的大弯曲路径，并由此穿过伊豆-小川脊较深的航道(约2500米)时，KE路径处于相对稳定的状态，有两条准静止的曲流。另一方面，当黑潮沿近岸非大弯曲路径通过海脊较浅部分(约1000米)时，KE路径趋于曲折，即处于不稳定状态。
A relationship between paths of the Kuroshio and Kuroshio Extension (KE) is investigated, using the satellite-derived altimetry dataset of 1993–2008. When the Kuroshio takes the nearshore nonlarge meander path or typical large meander path and resultantly goes through the deeper channel (about 2500 m) of the Izu-Ogasawara Ridge, the KE path adopts a relatively stable state with the two quasi-stationary meanders. On the other hand, when the Kuroshio takes the offshore nonlarge meander path and then passes over the shallower part of the Ridge (about 1000 m), the KE path tends to be convoluted, i.e., an unstable state.
