Abstract

It has been previously shown that atmospheric and oceanic heat and moisture transfers play an important role in the development of Arctic warming, and ocean surface temperature anomalies at low latitudes have a significant effect on the formation of transfers. Atmospheric circulation, which transports heat, moisture and precipitation, also affects climatic conditions in the catchment areas of the three main Siberian rivers—the Ob, Yenisei, and Lena—the flow of which is approximately half of the annual average inflow of river water into the Arctic Ocean. According to reanalyses and archival data for 1979–2019, air temperature and precipitation in the Ob, Lena, and Yenisei catchment areas are increasing. The greatest increase in precipitation is recorded in the spring months. There is also a maximum positive trend in air temperature in the spring months (March and April). To assess the impact of low latitudes on changes in climatic conditions in the catchment areas, data from ERA5, HadISST reanalyses, and the GPCC project precipitation gridded gauge-analysis data are used. Based on the average monthly surface air temperature at the nodes of the geographic grid in the Northern Hemisphere, the indices of zonal, meridional, and general circulation are calculated. To determine the relationships between indices and climatic parameters, the methods of multivariate cross-correlation analysis are used. It has been found that zonal atmospheric transfers have a significant impact on climatic conditions most of all in the cold part of the year, especially in November and March. In summer, the increase in zonal circulation is accompanied by a decrease in air temperature in the catchment areas, and meridional transfers increase the temperature. The greatest influence of the meridional transport is noted in spring and summer. Climate changes at low latitudes have the greatest effect in autumn on meridional transport in the spring season and on zonal transport in the cold part of the year, especially in March, with a delay of 2 years. The influence of low latitudes on climatic conditions in water catchments is presented in the form of graphs of correlations of climatic parameters and circulation indices on a generalized scheme.

低纬度地区对西伯利亚主要河流集水区气候条件的影响
摘要 以前的研究表明,大气和海洋的热量和湿气传输在北极变暖的发展过程中起着重要作用,低纬度的海洋表面温度异常对热量和湿气传输的形成有重大影响。输送热量、水汽和降水的大气环流也影响着西伯利亚三条主要河流--鄂毕河、叶尼塞河和勒拿河集水区的气候条件,这些河流的流量约占流入北冰洋河水年平均流量的一半。根据 1979-2019 年的再分析和档案数据,鄂毕河、勒拿河和叶尼塞河流域的气温和降水量都在增加。春季降水量增幅最大。春季月份(3 月和 4 月)的气温也呈最大正增长趋势。为了评估低纬度对集水区气候条件变化的影响,我们使用了ERA5、HadISST 再分析数据和 GPCC 项目降水网格测站分析数据。根据北半球地理网格节点的月平均地表气温,计算出了带状、经向和大气环流指数。为确定指数与气候参数之间的关系,采用了多元交叉相关分析方法。研究发现,在一年中的寒冷季节,尤其是 11 月和 3 月,地带性大气传输对气候条件的影响最大。在夏季,带状环流的增加伴随着集水区气温的下降,而经向传输则使气温上升。经向输送的最大影响出现在春季和夏季。低纬度地区的气候变化在秋季对春季的经向输送影响最大,在寒冷季节,尤其是 3 月份,对地带性输送的影响最大,延迟时间为 2 年。低纬度地区对集水区气候条件的影响,以气候参数和环流指数的相关图的形式在一个通用方案中呈现。

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.
