| 摘 要： | 针对经典气候跃变分析方法的存在的不足,并对有序样品的聚类方法引入统计显著性检验后,得到了一种研究气候跃变的层次聚类方法,此方法具有算法简单,统计意义明显,能获得不同层次上的跃变点的特点,应用此方法对北半球,云南省的昆明,蒙古,沾益进行了多层次的气候跃变研究,获得了一些有意义的结论。

| Abstract: | After introduced statistical significance test,a new method of analyzing the climatic abrupt change was advanced.The new method has such characteristics as simple algorithm,significance test,and obtaining the abrupt in different hierarchy.Used the new method to detect the abrupt characteristics in the anomalous temperature time series of the North Hemisphere,Kunming,Mengzi,and Zhanyi,some significant results have been obtain in different hierarchy. |
