Present state and dynamics of glacio-nival systems of Mongun-Taiga and Tavan-Bogdo-Ola mountain massifs
Climate-induced variations of glacio-nival systems (snow patches, glaciers, stone-ice formations) of the high-mountain massifs Mongun-Taiga and Tavan-Bogdo-Ola (north slope) were investigated for 1966-2013 period using results of field observations and analysis of aerial photos. Regional 25-year cli...
