Abstract—The paper presents the results of a study of spatiotemporal variability of the characteristics of the wind field in the free atmosphere of the Northern Hemisphere in the SEVIRI radiometer field of view of European geostationary meteorological satellites of the second generation Meteosat 8–Meteosat 11 in the time interval 2007–2021. It is noted that the maximum wind speeds, as well as the maximum average monthly and seasonal anomalies of the wind speed modulus, are observed over the Atlantic. A feature of the temporal variability of the area-averaged wind speed modulus is revealed, which consists in a change in the sign of the trend at the turn of 2015–2017 from positive to negative. At the same time, positive linear trends in the time intervals from 2007 to the points of a change in the sign of the trend over the Atlantic, the entire region under consideration and Eurasia, including the European territory of the Russian Federation, are significantly different from zero with a probability of more than 95% and the negative trend is significant only over the Atlantic. A high correlation was noted in the area of seasonal wind speed variations with the area of Arctic sea ice and temperature characteristics of the troposphere at levels of 500 and 200 hPa. Based on the analysis of the relationship between wind speed variability and the main climatic characteristics and large-scale atmospheric processes, a scheme is proposed for the effect of the accelerating reduction in the area of Arctic sea ice associated with global warming on wind speed in the free atmosphere.

摘要：本文介绍了欧洲第二代气象卫星Meteosat 8 – Meteosat 11的 SEVIRI 辐射计视场中北半球自由大气风场特征时空变化的研究结果。时间间隔 2007 年至 2021 年。值得注意的是，在大西洋上空观测到了最大风速以及风速模数的最大平均月和季节异常。揭示了区域平均风速模数的时间变化特征，即2015-2017年之交的趋势符号从正值变为负值。同时，从 2007 年到大西洋、整个区域和欧亚大陆（包括俄罗斯联邦欧洲领土）趋势符号变化点的时间间隔内的正线性趋势存在显着差异从零开始的概率超过 95%，并且负趋势仅在大西洋上空显着。季节性风速变化面积与北极海冰面积以及 500 和 200 hPa 水平对流层温度特征存在高度相关性。在分析风速变化与主要气候特征和大尺度大气过程关系的基础上，针对全球变暖导致的北极海冰面积加速减少对风速的影响，提出了方案。自由的氛围。
