气候突变现象的研究

Studies on the Observed Abrupt Climatic Change

本文分析了各种时间尺度的气候突变现象，特别是本世纪以来的三次主要气候突变（1900，1920和1960），讨论了十年尺度气候突变现象的几个主要特点：气候突变与全球温度变化的关系、突变的空间尺度以及季风系统在气候突变中的敏感性等．

The paper overviews the observed abrupt climatic changes on various time scales, with a focus on the analysis of three abrupt events (1900s, 1920s and 1960s) in the last century and discusses the major characteristics of the abrupt climatic change on a deeadal scale: the abrupt change in association with global temperature variation; the spatial scale of abrupt change and the posssible sensitivity of Asian monsoon system in response to the abrupt climate change.
