A model for calculating the mass-energy exchange and glacial runoff from sub-continental mountain glacier systems was developed using the experimental data from two years of field investigation in the Central Tien Shan of the former Soviet Union. The primary glacioclimatic factors controlling the current state of glaciation in this system were identified and quantified. The effect of this glacial system on the global hydrological cycle and share of the total atmospheric moisture input to this blind drainage system that is stored in the system were calculated. The interaction of the global atmosphere circulation change and state of glaciation was found. The components of mass balance of this glacial system for the last 300 years was also reconstructed.
