摘要:

: 基于库姆塔格沙漠周边6 个测站1961 ~ 2004 年的气温和降水资料,分析了该区域周边冬夏季气温、气温年较差和夏季降水的气候及气候变化特征。结果表明,6个站的降水和气温变化具有较高的相似性和一致性。沙漠周边的气温和降水呈增高和增加趋势,具有较明显的暖湿化趋势。除气温年较差外,夏季降水,冬、夏季气温均发生了气候突变。周期分析发现,夏季降水和气温在1970 年以前,以12 a 左右的周期变化为主,之后以24 a 左右的周期变化为主,冬季气温和气温年较差主要以8 a 左右的短周期变化为主。

Abstract:

on monthly air temperature and precipitation data at six stations from 1961 to 2004 around the Kumtage desert,the
variation characteristics of winter and summer air temperature,annual temperature range and summer precipitation around the region
were analyzed. The results show that the variation of air temperature and precipitation at six stations had well comparability and consistency
and presented increasing trend with obviously warm - wet change. Except for annual temperature range,the summer precipitation,
winter and summer air temperature all occurred climate jump. They were found by period analysis that the dominating period of
summer precipitation and air temperature before 1970 was about 12 years,and after 1970,it was 24 years,but the dominating period
of winter air temperature and annual temperature range was about 8 years.

Key words: Kumtage desert, climate change, air temperature, precipitation
