本文描述了千岛盆地的水循环及其在盆地中出现的大型反气旋涡流的形成和强度季节变化中的作用。 1977 年 6 月至 1979 年 6 月期间的海洋学数据表明，这些涡流在夏季形成，在冬季衰减。夏季，涡流的发展与盆地上空大豆暖流的表面流动以及来自特佩尼亚湾和萨哈林岛东部大陆架的冷、低盐、富氧水的深平流引起的等重线加深有关。在冬季，涡流衰减是由表面冷却和温暖的盐水表面水向下的对流混合引起的，这导致等密度上升并导致涡流衰减。夏季水流入该地区以及秋季和冬季涡流冷却的结合导致了涡流强度的年度变化。
This paper describes the water circulation in the Kuril Basin and its role in the formation and seasonal variation in intensity of the large anticyclonic eddies which occur in the basin. Oceanographic data for the period June 1977 through June 1979 suggest that these eddies develop in summer and decay in winter. In summer, the eddy development is associated with a deepening of the isopycnals caused by the surface flow of the Soya Warm Current over the basin, and the deep advection of cold, less saline, oxygen-rich water from Terpenia Bay and the eastern continental shelf of Sakhalin Island. In winter, the eddy decay is caused by surface cooling and convective mixing downward of the warm, saline surface water, which causes the isopycnals to rise and leads to an attenuation of the eddies. This combination of the summer influx of water into the region, and the fall and winter cooling of the eddies leads to the annual variation in eddy intensity.
