摘要:

利用Yamamoto方法对西宁和海东地区的年、季平均气温和降水资料进行突变分析,对资料进行均一化处理,进而讨论了该区的气候变化情况。结果表明:全年和春季的平均气温在1996年附近发生了增暖突变;北部地区的春季降水在20世纪80年代初发生了增多的突变;南部地区的冬季降水在20世纪70年代初发生了增多的突变;湟中、互助、大通3站的平均气温因迁址而产生了虚假突变,迁址对降水的影响不明显;在没有对比观测气差的情况下用相似法订正效果较好。西宁和海东的气温升高以冬季升温最为显著,降水各时段分布不均,总体有弱的减少趋势。

Abstract:

The abrup t changes ofmean annual and seasonal temperature, p recip itation in Xi’ning and Haidongwere examined by usingthe method of Yamamoto, meanwhile, the meteorological data were treated homogeneously, and climate change there was discussed.The results show that abrup twarming in mean annual and sp ring temperature occurred in 1996, and an abrup t increasing in sp ring p re2 cip itation took p lace at the beginning of the 1980 s in northern area, while an abrup t increasing in winter p recip itation occurred in the early 1970 s in southern area. There were inveracious abrup t changes inmean temperature in Huangzhong, Huzhu and Datong because of the meteorological stations removing, but this has little impact on p recip itation. The winter temperature increase was the most obvious in Xi’ning and Haidong area, and p recip itation p resented little decreasing trend as a whole.

Key words: climatic change, abrup t change test, meterological data correction, Xi’ning and Haidong area
