云南汛期雨量年代际转折突变的研究

The research of the inter-decadal abrupt turning of the flood season rainfall in Yunnan Province

    摘要
  • 摘要: 应用时间序列转折突变点的检测方法,对云南省18个代表站1951～1999年汛期雨量年代际转折突变进行了初步研究.结果表明:云南省18个代表站均存在明显的年代际转折突变.云南大部分地区汛期雨量在50年代发生了多雨转折突变;70年代发生了少雨转折突变;80年代以后云南大部分地区汛期雨量又发生一次多雨转折突变.

     

    Abstract: The inter-decadal abrupt turning of the flood season rainfall of 18 stations in Yunnan Province is studied.It is indicated by the results that there are obviously inter-annual abrupt turning points of the flood season rainfall in Yunnan Province.The dry-to-wet abrupt turning took place in 1950’s and after 1980’s;the wet-to-dry abrupt turning took place in 1970’s.
