Based on the numerical simulation of water circulation in the Sea of Okhotsk in 1986 to 2015, the impact of deep cyclones on the circulation off the northeastern coast of Sakhalin is studied. The circulation in the Sea of Okhotsk is simulated with the COSMO-Ru-INMOM-CICE model configuration, where the COSMO-Ru and INMOM resolve explicitly the mesoscale atmosphere and ocean dynamics and the CICE resolves the ice cover evolution. The extreme atmospheric events associated with the intensive cyclone activity over the Sea of Okhotsk during the cold season are classified. It is found that high velocity is typical of the cyclones coming to the sea from Sakhalin, and wind speed on the periphery is higher for the cyclones coming to the Sea of Okhotsk from the south and southwest. The analysis of water circulation response off the northeastern coast of Sakhalin demonstrates that the meridional current velocity on the shelf increased by several times from the sea surface to the bottom for all types of cyclones. On the edge of the shelf, southern currents intensified in the surface and bottom layers during the passage of cyclones and at the intermediate depths during the passage of fronts. On the continental slope, southern currents intensified in the surface, intermediate, and bottom layers depending on the type of extreme events.

三种类型的深层气旋经过鄂霍次克海期间萨哈林岛东北沿海的水循环

基于1986年至2015年鄂霍次克海水循环的数值模拟，研究了深层旋风对萨哈林岛东北海岸外循环的影响。鄂霍次克海的环流是使用COSMO-Ru-INMOM-CICE模型配置模拟的，其中COSMO-Ru和INMOM明确解析了中尺度大气和海洋动力学，而CICE则解析了冰盖演化。对与寒冷季节鄂霍次克海上空强烈的气旋活动有关的极端大气事件进行了分类。发现从萨哈林岛进入海中的气旋是典型的高速度，而从南部和西南部进入鄂霍次克海的气旋的外围风速较高。对萨哈林岛东北海岸外水循环响应的分析表明，对于所有类型的旋风，架子上的子午流速度从海面到底部增加了数倍。在架子的边缘，南部的海流在旋风通过时在表层和底层增强，而在锋面通过时则在中间深度增强。在大陆坡上，取决于极端事件的类型，南部海流在表层，中间层和底层均增强。南部气流在旋风通过时在表层和底层增强，而在锋面通过时则在中间深度增强。在大陆坡上，取决于极端事件的类型，南部海流在表层，中间层和底层均增强。南部气流在旋风通过期间在表层和底层增强，而在锋面通过期间则在中间深度增强。在大陆坡上，取决于极端事件的类型，南部海流在表层，中间层和底层均增强。
