Abstract

Based on average monthly data from the re-analysis of NASA MERRA-2 satellite measurements, the paper explores climatic changes in the temperature of the upper 1.5 meters of soil (TS), the thickness and area of the snow cover (SC), the moisture content of the top layer of soil 1 meter thick (SM) and air humidity at a height of 2 meters from the surface (AH) in the western part of the Russian Arctic (60°–75° N, 30°–85° E) for 1980–2021. The time interval considered is divided into two periods: 1980–2000 and 2001–2021. The differences between the average values of the parameters studied for these periods are calculated. The climatic changes that have occurred for the winter and summer seasons, as well as for each month of the year, are considered separately. Calculation of linear and quadratic trends has revealed an accelerating growth in the TS of the region studied in the period 2001–2021. A decrease in the thickness of the SC and a significant reduction in the area of the SC in November and April are shown. An increase in SM was found in the southwest and east of the region studied in the period 2001–2021, and a significant increase in AH in the western part of the Russian Arctic over the time interval studied is shown. Moreover, the growth of AH over the waters of the Barents, Kara and White Seas significantly accelerated in 2001–2021 compared to 1980–2000.

1980-2021年俄罗斯北极西部的气候变化。第2部分。土壤温度，积雪，湿度

基于NASA MERRA-2卫星测量数据再分析的月平均数据，本文探讨了1980-2021年俄罗斯北极西部(60°-75°N, 30°-85°E) 1.5 m以上土壤温度(TS)、积雪厚度和面积(SC)、1 m厚土壤顶层含水量(SM)和距地表2 m高度空气湿度(AH)的气候变化。考虑的时间间隔分为两个时期:1980-2000年和2001-2021年。计算了这些时期所研究的参数平均值之间的差异。冬季和夏季以及一年中每个月发生的气候变化是分开考虑的。线性和二次趋势的计算表明，2001-2021年期间研究区域的TS加速增长。在11月和4月，SC的厚度减少，SC的面积显著减少。在2001-2021年期间，研究区域的西南部和东部发现了SM的增加，俄罗斯北极西部的AH在研究的时间间隔内显着增加。此外，与1980-2000年相比，2001-2021年巴伦支海、卡拉海和白海海域的AH增长明显加快。

期刊介绍： The mission of Arctic, Antarctic, and Alpine Research (AAAR) is to advance understanding of cold region environments by publishing original scientific research from past, present and future high-latitude and mountain regions. Rapid environmental change occurring in cold regions today highlights the global importance of this research. AAAR publishes peer-reviewed interdisciplinary papers including original research papers, short communications and review articles. Many of these papers synthesize a variety of disciplines including ecology, climatology, geomorphology, glaciology, hydrology, paleoceanography, biogeochemistry, and social science. Papers may be uni- or multidisciplinary but should have interdisciplinary appeal. Special thematic issues and proceedings are encouraged. The journal receives contributions from a diverse group of international authors from academia, government agencies, and land managers. In addition the journal publishes opinion pieces, book reviews and in memoria. AAAR is associated with the Institute of Arctic and Alpine Research (INSTAAR) the oldest active research institute at the University of Colorado Boulder.
