| 摘 要： | 利用2007年7月1日至10月10日安装在七一冰川消融区的自动气象站资料,计算和讨论了能量平衡方程中的净辐射、感热和潜热通量、冰雪的热传输和降雨加热项.结果表明:净辐射是七一冰川的主要能量来源,其次是湍流感热.消融期消融耗热是主要的能量耗散,到消融末期,潜热耗热的比重开始增加.冰雪的热传导量值较小.同时还分析了暖季七一冰川区的小气候特征.

| Abstract: | Employing the Automatic Weather Station(AWS)installed on the Qiyi Glacier in the period of 1 July to 10 October,2007,the energy balance components including net radiation,sensible and latent heat fluxes,subsurface energy flux and the heat flux supplied by warm rainfall have been obtained and analyzed in detail.The microclimate features in summer have also been analyzed.It is revealed that the net radiation dominates the energy exchanges at the glacier-atmosphere interface;the turbulent sensible heat flux is... |
