  glacier accumulation
     Since the relation between the probability of occurrence of solid precipitation (S:%) and surface air temperature (T: C) is important for glacier accumulation, the relation of [S=-25T-108 ] is obtained from the observational results.

  glacier accumulation
During this weather in summer, snow-fall plays a key role in glacier accumulation.
      
To more accurately determine the role of glacier ice systems in sea level rise, glacier accumulation rate measurements are needed.
      


On glaciers in the eastern Tianshan Mountains, separate measurements of amounts of accumulation and abation are difficult, since accumulation and ablation occur simultaneously in the warm season. To estimate accumulation and ablation independently, meteorological observations around Glacier D-5 were made in summer. In comparison with air temperature on the ground, much lowering of that and smaller diurnal range were seen on the glacier. From the analysis of upper weather charts, the main cause of precipitation...

On glaciers in the eastern Tianshan Mountains, separate measurements of amounts of accumulation and abation are difficult, since accumulation and ablation occur simultaneously in the warm season. To estimate accumulation and ablation independently, meteorological observations around Glacier D-5 were made in summer. In comparison with air temperature on the ground, much lowering of that and smaller diurnal range were seen on the glacier. From the analysis of upper weather charts, the main cause of precipitation is attributed to the cold trough from the polar region. Since the relation between the probability of occurrence of solid precipitation (S:%) and surface air temperature (T: C) is important for glacier accumulation, the relation of [S=-25T-108 ] is obtained from the observational results. The relation between ablation (a : cm water) and the degree day index (∑T: sum of daily mean air temperature. (.day) is also obtained as [a = 1.5∑T]. By the use of these relations, accumulation, ablation and balance on the glacier are estimated. The agreement between the calculated balance and observational results is fairly good except when the glacier is covered by new snow with high albedo Meteorological conditions and mass balance arc compared briefly with those in the Nepal Himalaya.

在东天山冰川上,积累和消融是在暖季同时发生的,故分别对积累量和消融量的测量是困难的。为了单独估算积累和消融,夏天我们在D-5冰川附近进行了气象观测。与地面气温相比较,发现冰川上气温比较低,且具有较小的日变化幅度。由高空天气图的分析可知,降水的主要原因可归结于来自极地的冷槽。固态降水发生的频数(S:%)和地面气温(T:℃)之间的关系对冰川积累很重要,这种关系(S=25T+108)可由观测结果得到。消融(a:厘米水层)和日积温(∑T:日平均气温之和,℃·日)也可由关系式(a=1.5∑T)得到。通过这些关系的应用,我们可以估算冰川上积累、消融和物质平衡。除冰川为具有高反射率的新雪所覆盖面外,计算的物质平衡和观测结果很吻合,气象条件和物质平衡与尼伯尔喜马拉雅山冰川进行了简要的比较。

The fundamental idea is that relief configuration and thus the type of glaciation depend on the location of the snowline within a certain landscape. Together with a method of snowline detemination the author has developed a calculation scheme with which the characterizing gradient relationships of subrecent and present glaciers can be fixed. The angles a and were calculated for 223 glaciers from 12 various mountain regions of the earth and plotted in a scatter diagram.

分类的基本出发点是认为在一定的景观条件下,雪线的位置决定地形结构,因而也决定冰川作用类型。根据特征地形参数有可能对冰川进行分类。 作者提出一种计算图,它同雪线确定法相结合,能判定不久以前的冰川和现代冰川的特征坡度关系(Kuhle,1985a)。以阿列奇冰川为例来说明这一方法(图1和图2)。其中,中值高度(即少妇峰4158m的最高峰值与1503m的冰川末端值的数学平均)以上各支冰川顶点(只算顶峰)的平均值视作冰川积累区的上限。效仿霍费尔(V.Hfer,1879)的方法,将积累区的平均上限(3875m)与冰川末端高度(1503m)进行数学平均,求出数学雪线(S_((m))=2689m)。沿冰川流动方向,从S_((m))点量到积累区最高点(只到积累区平均上限),取其在水平面上的投影作为水平距离(b)。若是复合型冰川,水平距离则要对每主要支冰川逐一进行计算。以同样的方法算出冰川末端到S_((m))的水平距离(e)。用正切关系式,不难从水平和垂直距离求出倾角α和δ(图2)。作者计算了地球上12个不同山区的223条冰川的α和δ值,并点绘成分布图(图3)。 为了使数值分类具有现象学特点,即概念上易被接受,分类仍...

In this paper, the tracks of moisture transportation on the Qinghai-Xizang Plateau are discussed. It is found that the warm wet current in Tibet from Indian Ocean. There Are two tracks of moisture transportation, the one is east way, from Bay of Bengal, along the Brahmaputra, Yar-lungzangbo River northward into the northern region of the plateau and its tributaries are represent the form of "wet tongue"; the other is the west way, but it varies with the seasons, or from India direct leap over the Himalaya monutains into the plateau, or from Pakistan, Afghanistan through the Pamir plateau and gets into Ngari Region in Tibet.The relationship between the moisture transportation tracks and the distribution of modern mountain glaciers in Tibet are discussed too.

青藏高原的水汽主要来源于印度洋,其水汽输送路径可分为东西两条,东线为印度洋暖湿气流自孟加拉湾沿布拉马普特拉河、雅鲁藏布江(或横断山三江河谷)伸入高原北部边缘地带,为念青唐古拉山冰川发育提供物质基础,另一支西线来自印度洋阿拉伯海,其输送路线因季节不同而有差异,云团或自印度半岛腾空跨入高原,或自印巴次大陆经帕米尔高原沿南疆盆地南縁进入西藏阿里,为西喜马拉雅山、喀喇昆仑山和昆仑山丰厚的冰川积累起着重要作用。 水汽输送路径探讨,对合理开发利用青藏高原水资源具有理论和生产意义
