| 摘 要： | 利用2006年5～6月和2007年5～6月中国科学院HEST大气科学实验在珠峰绒布寺河谷野外观测期间获得的观测资料,分析了珠峰地区河谷近地层风向、风速、温度、湿度和CO2的日变化特征,讨论了珠峰北坡冰川风和山谷风的特点以及高原地表辐射、地表反照率和近地层湍流通量的变化特征.结果表明:在复杂地形和特殊下垫面影响下,珠峰绒布河谷地区近地面层各个气象要素和湍流通量日变化特征显著,并且明显存在冰川风和山谷风复合的局地环流,冰川风对该地区地气间物质能量交换起着重要作用.

| Abstract: | Mount Qomolangma is a typical area with special land-surface atmosphere interaction over Tibetan Plateau, due to its high elevation and complicated terrain. The process can be better understood by observing the interaction itself and analyzing the variation of atmospheric elements and turbulent fluxes. Based on the turbulent data obtained in Rongbuk valley on northern slop of Mount Qomolangma during June 2006 and June 2007, the diurnal variation of micrometeorological elements and turbulent fluxes are investigated by using eddy covariance method. Results show that the diurnal cycles of micrometeorological elements and turbulent fluxes, such as wind, temperature, humility, sensible heat flux, latent heat flux etc. , are evident. Glacier wind blowing from noon to midnight are observed in this area. They play an important role in the mass and energy exchanges in the land-surface process of Rongbuk valley. |
