  • Measurement and estimative models of glacier mass balance in China
  • China ; Glacier ; Glacier mass balance ; Glaciology ; Ground survey ; Model ; Monsoon ; Mountain
  • Attibuted to high altitude and inland location, the glaciers in China are characterized by very low temperature. The prevailing monsoon climate delivers most of the annual precipitation over glaciated areas of China in the summer, making the major
  • by net accumulation and net ablation during the year. The monitored glaciers are few compared with the large glacierized area in China. Some estimative models are thus introduced.
