Abstract:

本文采用2010~2019年新疆吉木乃县沙吾尔冰川沿山一带5个气象自动站观测资料,对冰川近地层气象要素进行分析,结果表明:各站的月平均气温年际变化基本同步,温度与靠近冰川的位置有较大的关系,离峰顶越近,海拔越高,温度越低。夏季山区热力作用相对较强,对流而形成的降水比较充沛,各站降水分布都有一定的相似性。受地形和下垫面的影响,冰川上部的局地环流较弱,而下部的山谷风非常发育。
Based on the observational data of 5 metereological stations Around the Sawuerglacier in Altay area from 2010 to 2019, the Basic meteorological elements were discussed, The results showed that the annual variation of monthly mean temperature in each station is basically synchronou, there is a strong relationship between temperature and the location near the glacier strong wind and extreme cold; The closer you get to the summit, the higher the altitude, the lower the temperature. The thermal effect of Mountain area is relatively strong in summer, Convection and the formation of more abundant precipitation, the precipitation distribution of each station has certain similarity. Influenced by the topography and underlying surface, the local circulation in the upper part of the glacier is weak, but the valley winds below are very well developed.
