摘要
本文利用40年的气象资料,分析了最近10年(1981-1990年)新疆气候变化的主要特征:暖冬突出、年平均气温上升、年降水量增加、寒潮天气减少、最大冻土深度变薄、冬季最低气温偏高与暖冬有关的异常在气现象增多.同时,还对暖冬形成的原因和暖冬对国民经济及社会各方面的影响做了初步分析.
This paper analyses the major fecture of climatic change in Xinjiang based on 40-yearmeoteorological data (1950-1990). The following conclusions are obstaincd: (1)Warm win-to is a main fact of climatic changes for recent 10 years (1980-1990), and it shows the risingof annual mean temperature, decreasing of cold-wave weather, thinner maxinum frozenearth depth, and more abnormal weather related to warm winters. (2) The temperature insummer is decreasing a little. (3) Precipitation in all of Xinjiang is increasing. The prccipita-tion is close to that of in 1950's. (4) The typical Eurasion circulation model during the warmwinters in Xinjiang is due to stronger Atlantic coast wedge, deeper Eurcap trough andstrong Xinjiang wedge.
