We tried to understand scale-interactions between the regional oceanic phenomena such as the Kuroshio meander and the basin-wide ocean climate phenomena such as El Nino. Our study region covers the North Equatorial Current, the Kuroshio and the Kuroshio Extension in the Subtropical Gyre. The present research discussed the following phenomena and clarified mechanisms using data analysis methods and numerical simulations. Those are 1)interannual variations of the seasonal evolution of the Mindanao Dome and their relation with El Nino, 2)relations between El Nino and the bifurcation latitude of the Kuroshio and the Mindanao Current, 3)relations among El Nino, the Kuroshio transport and the Luzon Strait throughflow, 4)relations between the Kuroshio veering phenomenon southwest of Kyushu and the joint effect of baroclinicity and bottom relief, 5)roles of meso-scale eddies in the Kuroshio meander, 6)<Furiwakeshio> (branching of the Kuroshio impinged on the Kii Peninsula), 7)influences of the Izu-Ogasawara Ridge on the seasonal variation of the Subtropical Gyre system, and 8)relations between the 1988/89 warming in the surface layer of the northern North Pacific and the variation of the Subtropical Gyre system. All the above results are mostly published in well-known international journals.

我们试图了解区域海洋现象（例如黑鲁道蜿蜒与盆地范围内海洋气候现象（如厄尔尼诺））之间的规模相互作用。我们的研究区域涵盖了亚热带回旋中的北赤道电流，黑鲁希木和黑鲁氏延伸。本研究讨论了以下现象，并使用数据分析方法和数值模拟阐明了机制。这些是1）棉兰老族圆顶季节性演变的年际变化及其与El Nino的关系，2）El Nino与黑果岛的分叉纬度之间的关系和棉兰老岛的分叉纬度，3）El Nino之间的关系Luzon海峡泛滥，4）九州西南部的黑鲁道河转向现象与斜压和底部浮雕的关节效应之间的关系，5）在黑子曲折中，中等尺度涡流的角色，6）<furiwakeshio>在KII半岛上，7）Izu-Ogasawara山脊的影响对亚热带Gyre系统的季节性变化，以及8）1988/89之间的关系Gyre系统。以上所有结果主要发表在著名的国际期刊上。
