摘要
气候突变现象及其理论的研究是近代气候学一个新兴的研究领域.本文是气候突变研究评述的第一部分,着重讨论了突变,主要是气候突变的定义和气候突变信号的各种检测方法.把气候突变归纳为四类,即均值突变、变率突变、转折突变和翘翘板(seasaw)突变.并通过Mann-Kendall法的检测,发现在本世纪20年代经历了一次全球范围的气候突变.
This is part of the review on study of abrupt climatic change, addressing mainly the definition of catastrophe and abrupt change of climate, the detecting methods of abrupt changes of various types, such as changes in mean, changes in variability, transit jump and seesaw jump.Finally the Mann-Kendall rank statistical test is applied to detect the abrupt change in 1920's on global scale.
