Climatic characteristics of temperature, humidity, and wind velocity in the atmospheric boundary layer over western Siberia

Temperature regime of the atmospheric boundary layer over Siberia

“…This work covers the temperature observations in the atmospheric boundary layer over the Siberia territory for the period from 1981 to 2020. As the source material, as in 17,18 , we used the data of long-term (1981-2020) two-time (00 and 12 hours GMT) radiosonde observations (http://www.weather.uwyo.edu/) of 24 aerological stations located in different latitudinal zones of the Siberian region. Western Siberia is represented by 10 stations: Dikson (polar latitudes (70-75N)); Salekhard, Turukhansk, Aleksandrovskoe, Bor (subpolar latitudes (60-70N)); Verhnee Dubrovo, Tobolsk, Omsk, Novosibirsk, Yeniseisk (temperate latitudes (50-60N)).…”

“…The air temperature regime has been well studied near the earth's surface [11][12][13] and in the free atmosphere [14][15][16] . The vertical structure of meteorological fields, in particular air temperature, is less studied in the atmospheric boundary layer 17,18 , especially for such vast region with a rare network of aerological observations, as Siberia. In addition, in the current conditions of global warming 16,[19][20][21] , there is a need to reassess the characteristics of the ABL temperature both at the global and regional levels taking into account the latest data 13 .…”

“…In addition, in the current conditions of global warming 16,[19][20][21] , there is a need to reassess the characteristics of the ABL temperature both at the global and regional levels taking into account the latest data 13 . In previous works on the study of the statistical structure of temperature fields in the atmospheric boundary layer, an analysis was carried out for the territory of Western Siberia according to the data of 8 aerological stations for the period from 2001 to 2007 17 , and for Eastern Siberia according to the data of 8 stations for the period from 2001 to 2010 18 .…”

Air humidity in the atmospheric boundary layer over Siberia

“…Therefore, there is a need to obtain statistical characteristics taking into account modern data, and especially for the atmospheric boundary layer, where up to 50% of the total mass of water vapor is contained, while there is 98-99% in the troposphere 16,17 . In previous works on the study of air humidity fields in the atmospheric boundary layer, the analysis was carried out for Western Siberia according to the data of 8 aerological stations for the period from 2001 to 2007 18 , and for Eastern Siberia according to the data of 8 stations for the period 2001-2010 19 .…”
