概要 | Direct current measurements were carried out along ASUKA(Affiliated Surveys of the Kuroshio off cape Ashizuri) line crossing the Kuroshio from Shikoku coast, Japan to 25 °N, during 1993-1995. The temp...orally averaged views of the Kuroshio show that most strongly flowing part, the Kuroshio flow axis, at about 700 m depth is located around 32 °N and it spreads down to about 2000 m depth. Weak countercurrents are detected just above the continental slope and strong countercurrents are also detected near the deepest end of the continental slope. At a reference depth of 650 m, the Kuroshio flow axis coincides with 7° C isotherm. The Kuroshio takes two distinct paths: a near-coast path and a far offshore path. For each case, a horizontal velocity profile at 650 m depth is estimated on a stream coordinate that denotes the component parallel to the velocity at the Kuroshio flow axis.続きを見る |
