    Abstract

    Energy and mass balance model for snow is an essential tool for future projection of snow and ice storage. However, the snow models in hydrologic engineering field have barely considered the long-term behavior of glaciers because the time scale of glacier dynamics is much longer than those of river flow and seasonal snowmelt. This study proposes an appropriate treatment for inland glaciers as systems in dynamic equilibrium that stay constant under a static climate condition. The snow/ice vertical movement from high elevation areas to valleys (lower elevation areas) by means of wind redistribution, avalanches, and glaciation should be considered as an equilibrator of the glacier system. To demonstrate this concept, a simple dynamic equilibrium glacier model for regional to global scales is proposed and applied to the Pamir Glaciers. The glaciers in the Pamir Mountains may lose about half of their volume by the end of 21st century by the anticipated global warming based on nine selected general circulation model (GCM) projections.
