Abstract

An analysis of water exchange between the Bering (Pacific Ocean) and Chukchi (Arctic Ocean) seas in the summer was carried out using satellite data on sea level, geostrophic currents, and measurement data of water transport in the Bering Strait. It is shown that there is good agreement (r = 0.85, July–October 1997−2019) between the velocities of geostrophic currents (satellite data) and measurements of water transport (buoy station data) through the Bering Strait. It has been established that the temporal variability of water transport through the Bering Strait is determined by sea level variations in the southern part of the Chukchi Sea (66°–68° N, 170°–172° W). Strengthening of the eastern (western) winds is accompanied by a decrease (increase) in the sea level in the southern part of the Chukchi Sea and, as a result, an increase (decrease) in the flow of water through the Bering Strait. An increase (decrease) in the flow of the Yukon River is accompanied by a rise (decrease) in sea level and changes in water circulation in the northern Bering Sea and the southern Chukchi Sea.

风和育空河径流对白令海和楚科奇海之间水交换的影响

摘要利用白令海峡的海平面、地转流卫星数据和水输送测量数据，对夏季白令海（太平洋）和楚科奇海（北冰洋）之间的水交换进行了分析。结果表明，白令海峡的地转海流速度（卫星数据）与水流输送测量数据（浮标站数据）之间存在良好的一致性（r = 0.85，1997-2019 年 7-10 月）。已确定通过白令海峡的水流输送的时间变化是由楚科奇海南部（北纬 66°-68°，西经 170°-172°）的海平面变化决定的。东（西）风的增强伴随着楚科奇海南部海平面的降低（升高），因此，通过白令海峡的水流增加（减少）。伴随着育空河流量的增加（减少），白令海北部和楚科奇海南部的海平面上升（下降），水循环发生变化。

期刊介绍： Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
