Abstract:

利用西北地区121个气象站1961-2011年降水量资料,分析了西北地区春季降水的基本气候特征;通过EOF、REOF、功率谱等方法,对西北地区春季降水的时空特性进行了研究,用Mann-Kendall检验法检验西北地区春季降水序列是否存在突变现象.结果表明西北地区春季降水空间分布极不均匀,其空间分布特征是东南部和西北部为多雨区、中间为少雨区.西北地区春季降水在第一空间尺度上为全区一致,在第二空间尺度上可分为2个自然气候区,在第三空间尺度上可分为6个自然气候区.从年代际变化来看,1980年代是近半个世纪来降水最多的10a,1970年代是降水最少的10a;西北地区春季降水的年际变率十分显著,降水最多的年份是最少年份的3倍多.1961-2011年间西北地区春季降水发生了明显的突变1973年出现了一次趋于减少的突变,1985年出现了一次趋于增多的突变.18~19a的长周期是其主要周期,其次是5a和7a的短周期.未来20a西北地区春季降水量呈缓慢下降的趋势.
