英文摘要	To identify the atmospheric controls of the summertime glacier surface energy balance in the Himalayas, in situ meteorological data collected at 6,523 m above sea level during May-July 2005 were obtained and analyzed. Our results showed that net shortwave radiation (103 W m(-2)) and turbulent sensible heat flux (12 W m(-2)) acted as energy sources, and net longwave radiation (-62 W m(-2)) and turbulent latent heat flux (-20 W m(-2)) represented heat sinks. Cloud cover controlled the summer surface energy balance. During the active period of the South Asian Summer Monsoon, the frequent cloud coverage increased the incoming longwave radiation more than it decreased the incident solar radiation. Intensification (weakening) of the South Asian Summer Monsoon strengthened (suppressed) surface melting. The melt energy measured during the nonmonsoon period was small due to the energy consumption associated with glacier volume warming, energy loss from sublimation, and large heat loss through net longwave radiation due to the low amount of incoming longwave radiation caused by the low cloudiness. The comparison of glacier surface energy balances on the Tibetan Plateau shows that on continental glaciers, net radiation is lower and accounts for a smaller contribution to energy sources, and the dominant energy sinks are sublimation and evaporation, rather than melting, which is the primary energy sink for maritime/subcontinental glaciers. This implies an important spatial variability in glacial sensitivity to different climatic conditions on the Tibetan Plateau. Key Points Based on in situ data obtained at 6,523 m above sea level, the glacier surface energy balance and its atmospheric controls are examined Clouds governed the surface energy balance by decreasing the incident solar radiation less than increasing the incoming longwave radiation The dominant energy sinks shift from sublimation/evaporation on highly continental glaciers to melting on maritime/subcontinental glaciers
