Research Abstract |
The impact of stratification structure in the Okhotsk sea on meso-scale eddy activity around the Kuroshio extension is investigated with 3-layer model. The eddy scales and activities were large when the second layer was thick in the Okhotsk sea. As we showed the strong relationships that deep mixed layers were frequently observed in the core of anti-cyclonic eddies, the eddy activity changes revealed in the numerical experiment might be influent on the circulation in the upper layer as well as in the mid depths.
