托木尔峰地区神奇峰冰川3950m处物质平衡与气象要素关系分析

2008年夏季,中国科学院天山冰川观测试验站科研人员对天山托木尔峰地区神奇峰冰川（也称青冰滩72号冰川）进行了大规模综合性的野外科考活动,获得了2008年7月30日至8月31日期间的冰川海拔3950m处的实测气象资料,包括气温、降水等。文中将这些气象资料与物质平衡数据相结合,对它们的关系进行了分析。2008年夏季青冰滩72号冰川野外观测资料分析结果表明：研究时段内,冰川日平均气温在0℃以上的天数达到了96%,冰川基本上处于消融状态;降水前后伴随的气温变化幅度大;基于观测数据,对气温和物质平衡进行了回归分析,回归系数为0.631;并利用灰熵关联度分析了降水和物质平衡之间的关系,它们之间的关联度系数为0.497。

The relationship between the mass balances and meteorological factors at the glacier of No.72,Qingbingtan,Shenqi Peak,Tuomuer Area

Tianshan Mountain glacier monitoring station,Chinese Academy of researchers carried out a comprehensive scientific exploration activities at the Shenqi Peak Glacier,Tuomuer Area in 2008.Shenqi Peak Glacier can also be called Qingbingtan Glacier No.72,and obtained the glacial weather data,including temperature,precipitation and other first-hand weather information during July 30,2008 to August 30,2008 at 3950m a.s.l.Combining elements of different weather conditions and melting of glaciers,we explored the meteorological elements and the relationship between the melting glaciers at the Glacier of No.72,Qingbingtan,Tuomuer Peak in the ice extremely high altitudes(3950m a.s.l.) to obtain fixed-point meteorological observational data.The results showed that the glacier is in the melting state,the regression coefficient between temperature and mass balance is 0.631,the grey entropy correlation coefficient between precipitation and mass balance is o.497.
