Abstract Using the eddy-permitting model, circulation in the Okhotsk Sea and in an adjacent area of the Pacific Ocean is retrospectively simulated from 1991 to 2000. It is shown that the Sea has four types of circulation, each one for its own season with a strengthening of all currents in winter and a weakening in summer. We estimate and analyze the values of the simulated monthly-averaged volume transport of the main currents: the coastal branch of the East Sakhalin Current, the over-slope branch of the East Sakhalin Current, the coastal branch of the North Okhotsk Current, the over-slope branch of the North Okhotsk current, the Middle Current and the West Kamchatka Current. In contrast to the conventional circulation schemes, the North Okhotsk Current is found to consist of two branches, one over a continental slope and another along the northern shelf. The simulation results on the double-branch structure of this current are found to be in a reasonable agreement with instrumental measurements, CTD observations, satellite data and other oceanography reanalysis.

从数值模型看鄂霍次克海的新环流特征

摘要 利用涡流模型，对鄂霍次克海及邻近太平洋海域环流从 1991 年到 2000 年进行了回顾性模拟。冬季所有洋流加强，夏季减弱。我们估计和分析了主要洋流的模拟月平均体积输运值：东库页岛海流的沿海支流，东库页岛海流的斜坡支流，北鄂霍次克海流的沿海支流， -北鄂霍次克海流、中海流和西堪察加海流的斜坡支流。与传统的环流方案相比，北鄂霍次克洋流被发现由两个分支组成，一个在大陆坡上，另一个在北部大陆架上。发现该洋流双分支结构的模拟结果与仪器测量、CTD观测、卫星数据和其他海洋学再分析具有合理的一致性。
