Based on direct observations of the Central Tuiyksu glacier for period 2006…2023, calculations components external and internal mass transfer are presented comparison obtained values periods 1958…1972 1977…1992 is provided. To determine kinematic balance, stakes drilled into ice with geodetic reference ground were used. During considered period, retreated by 420 meters, balance average was -0,54 m w.e., entire observation since 1958, 1190 value -0,42 w.e. 1956…2023. The annual in...
Impacts of projected climate and glacier change on river discharge in five glacierized catchments the northern Tien Shan, Kazakhstan are investigated using a conceptual hydrological model HBV-ETH. Regional PRECIS driven by four different GCM-scenario combinations (HadGEM2.6, HadGEM8.5, A1B HadCM3Q0 ECHAM5) is used to develop projections. Future changes glaciation assessed Blatter–Pattyn type higher-order 3D coupled ice flow mass balance model. All scenarios show statistically significant...
Abstract We describe changes in glaciers of the Balkhash-Alakol basin, central Asia, and analyse unified glacier inventories Zailiyskiy-Kungei Jungar systems Chinese part Ili river as well mass-balance monitoring data from Tsentralniy Tuyuksu for period 1957-2014. In spite significant inter-basin differences, glaciation three glacial basin within Kazakhstan territory is changing simultaneously similarly. Differences rates degradation are small affected primarily by orientation flanks...
Continuous measurements of glaciological mass balance have been conducted at the Central Tuyuksu glacier, group glaciers, Ile Alatau, northern Tien Shan since 1957 showing that cumulative was negative 1970s. Geodetic calculated for 1958-1998 and 1998-2016 periods using multi-temporal digital elevation models derived from historic photogrammetric surveys 1958 1998, high-resolution Pleiades satellite stereo imagery 2016. revealed mean surface lowering 23.2±2.2 m (0.40 ± 0.04 a-1) reduction in...
Abstract. Changes in glacierized area the Kazakhstani sector of Tekes River basin were assessed using Landsat and KH-9 imagery from 2013, 1992 1976. Between combined 118 glaciers declined 121.4 ± 9.2 km2 to 105.0 5.5 km2. The total loss was 16.4 5.9 or 13.5 7.5 %. rate reduction 0.78 a-1 0.64 % a-1. This is lower than other regions northern Tien Shan because presence several large sample. glacier 2013 exceeds reported by RGI5.0/GAMDAM inventories for 1999–2003 24 latter did not include areas...
The article considers the possibilities of assessing glaciation area the Northern Ile and Ile-Kungey glacier systems based on monitoring data from a limited sample test glaciers. During testing in each mentioned systems, two samples 10 glaciers, their total (20 glaciers) share glaciers named regions, corresponding system was calculated. According to results, values of correlation coefficient calculated actual (based results cataloguing) for three were 0.99, 0.98, 0.99 0.97,...
The study considers the results of numerical modeling mass balance Central Tuyuksu Glacier, located on northern slope Ile Alatau, Northern Tian Shan, using DMBSim model. A comparison was conducted between computed values both winter and annual balances measurements obtained during years 2006-2023. input data for included glacier accumulation, ablation, derived from stakes, as well snow surveys with pit measurements. Additionally, air temperature precipitation weather station total gauges...
В статье приведены результаты изменения оледенения и гляциальных озер бассейна реки Каратал на основе данных дистанционного зондирования. Определены морфометрические характеристики ледников озер. Проведено сравнение параметров за разные временные срезы, оценены темпы деградации динамика рассматриваемого бассейна. Отступление сопровождается увеличением числа площади озер, расположенных молодых моренах. Установлено, что 55 лет площадь сократилась 89,35 км2 (на 44,12 %), количество увеличилось...
