在 2005 的脱离季节的气象学的数据被二个自动气象站在 Keqicar 冰河上记录,在中国的西南 Tianshan 山。一个人被操作有 4,265 m (地点 A ) 和另外一个的高度的平衡线附近的冰河被操作有 3,700 m (地点 B ) 的高度的冰河脱离区域。这些数据被用来分析气象学的条件和 Keqicar 冰河的表面精力平衡(SEB ) 。网放射直接被测量,并且狂暴的热流动用体积是计算的空气动力学的途径,包括稳定性修正。从四根脱离木桩导出的 0.68 m w.e 的脱离价值在观察时期期间在到 0.71 m w.e 的建模的价值的靠近的通讯,为 81.4 ofthe 的网放射报道与它 63.3 W/m2 的价值总计精力。剩余的精力来源被理智的热流动提供 14.4 W/m2 的价值。精力主要被融化和蒸发消费,为有他们 54.0 和 23.0 W/m2 的价值的 69.5 全部的精力和 29.7 的财务分别地。放射的精力在冰河空气接口统治精力交换,在网络短波由变化管理了放射。网短波放射由于阴沉和稳固的降水引起的高反照率的效果显著地变化。风速度区别地影响狂暴的热流动,理智的热流动和潜伏的热流动在有高风速度的 7 月是大得多的。
The meteorological data of ablation season in 2005 were recorded by two automatic weather stations on Keqicar Glacier, in the southwest Tianshan Mountains of China. One is operated on the glacier near the equilibrium line with an altitude of 4,265 m (Site A) and another is operated on the glacier ablation area with an altitude of 3,700 m (Site B). These data were used to analyze the meteorological conditions and the surface energy balance (SEB) of Keqicar Glacier. Net radiation was directly measured, and turbulent heat fluxes were calculated using the bulk aerodynamic approach, including stability correction. The ablation value of 0.68 m w.e. derived from four ablation stakes is in close correspondence to the modeled value of 0.71 m w.e. During the observation period, net radiation accounts for 81.4% of the total energy with its value of 63.3 W/m2. The rest energy source is provided by the sensible heat flux with a value of 14.4 W/m2. Energy is consumed mainly by melting and evaporation, accotmting for 69.5% and 29.7% of the total energy with their values of 54.0 and 23.0 W/m2, respectively. Radiative energy dominates energy exchanges at the glacier-atmosphere interface, governed by the variation in net shortwave radiation. Net short-wave radiation varies significantly due to the effects of cloudiness and the high albedo caused by solid precipitation. Wind speed influences the turbulent heat fluxes distinctively and sensible heat flux and latent heat flux are much larger in July with high wind speed.
