利用天山南坡科其喀尔冰川3号观测站2009年全年的气象观测资料,分析研究了科其喀尔冰川表碛区的小气候特征.结果表明:总辐射和净辐射夏秋季较高、冬春季较低;反射辐射和地表反照率反之.与其他地区不同,该区主要受积雪物理性质和下垫面状况的影响,冬春季地表反照率日变化表现为由大到小的变化过程,夏秋季表现为倒U型.温度年变化表现为夏秋季高、冬春季低,最高月均值出现在8月,为9.4℃,最低月均值出现在1月,为-9.6℃.受山谷风和冰川风的影响,全年的风向以西北风和西北偏西风为主,风向的日变化以11:00为界发生转向.受降水和冰川消融等的影响,比湿夏秋季月均值较大,冬春季月均值较小.
Based on the meteorological observation data of the observation station of Keke’er glacier No.3 on the southern slope of Tianshan Mountains in 2009, the microclimate characteristics of the moraine area in the Keke’er glacier are analyzed. The results show that the total radiation and net radiation are higher in summer and autumn, In contrast with other regions, the area is mainly affected by the physical properties of snow cover and the underlying surface conditions. The diurnal variation of surface albedo in winter and spring showed a process of descending from small to large , And showed the shape of inverted U in summer and autumn.The annual variation of temperature showed high in summer and autumn, low in winter and spring, the highest monthly mean appeared in August, 9.4 ℃, the lowest monthly mean appeared in January, -9.6 ℃. And the influence of glacier wind, the annual wind direction is dominated by the northwest wind and the northwestern westerly wind, and the diurnal variation of the wind direction turns around at 11:00. Affected by the precipitation and glacier ablation and so on, , The monthly average of winter and spring is smaller.
