Аннотация: The aim of the study is to estimate the amplitudes of mean temperature fluctuations in the central Russian Altai during the warm period in the late Holocene. The simulation model for glaciers budget developed by Galakhov was applied to paleogeographic reconstructions. The model is based on the data obtained experimentally from two glacier catchments in the central Russian Altai, i.e. the Aktru River basin (the North-Chuisky ridge) in 1977-1986, and the Multa River basin (the Katunsky ridge) in 1969-1973. The simulation model was tested in the Multa River basin. The model for the Multa basin was used to evaluate changes in mean temperature of the warm period for the Aktru cooling that occurred 750-150 years ago (-0.2◦C) and the Akkem one 4900-4200 years ago (-0.9◦C). The results suggest a good correlation with paleoclimatic reconstructions of the Aktru River basin.
