Current State of the Altai Glaciers (Russia) and Trends Over the Period of Instrumental Observations 1952–2008

摘要

Results of research into climate and glacier dynamics in the Altai Mountains (Russia) over the period of instrumental observations (1952–2008) are presented in this article. About 1030 glaciers with a total area of 805 km~2 and volume of 42.5 km~3 have been recorded in the Altai Region. The average summer air temperature in different regions of the Altai has increased during the study period from about 0.2℃ (Aktru) to 1.1℃ (Akkem). The annual atmospheric precipitation rate has also increased, by 8–10%. Since 1952, the glacier area in different regions of the Altai has decreased by 9–27%, and volume by 12–24%. By 2008, as a result of degradation, the total number of glaciers was 953 with an area of 724 km~2 and volume of 38 km~3.
