A New Method of Analysing Climate Jump and Its Application
-
摘要: 在探讨目前气候跃变方法的基础上,针对其存在的缺陷,引入费希尔(Fisher)最优分割法,并与原方法的统计检验相结合,得到一种新的研究气候跃变的方法。运用该方法对西北地区东部的西安、宝鸡、汉中3地的旱涝等级序列进行气候跃变研究,可知西北地区东部旱涝气候跃变存在局地性和非局地性的特征。Abstract: On the basis of approaching the current methods of climate jump, being aimed at the faults of those methods, Fisher optimum separation method is introduced and combined with the statistic test of those, thus a new method is produced. By using this method, the climate jumps about drought/flood series for Xi’an, Baoji and Hanzhong areas are studied, respectively. The results show that there exist local and non-local climate jumps in eastern Northwest China
