Meso-scale eddies along the Kuroshio Extension and their roles for mixing

利用三层模式研究了鄂霍次克海层结结构对黑潮延伸区周围中尺度涡动活动的影响。鄂霍次克海第二层较厚时，涡动规模和活动都较大。由于反气旋性涡旋的中心常出现深混合层，数值试验中所揭示的涡旋活动的变化不仅对中层环流有影响，而且对上层环流也有影响。

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.
