摘　　要：概述了全球尺度、我国大范围区域及长江中下游梅雨的年代际气候变化的一些研究进展,重点介绍了近期我国气象工作者有关这方面研究的一些成果。指出:①全球尺度的大气、海洋及气温变化不仅存在明显的年际变化,而且年代际变化也十分显著;②受全球气候年代际变化的影响,中国气候也存在多时间尺度的变化特征,但气候的年代际变化特征与全球气候年代际变化有不同之处;③长江中下游梅雨气候变异不仅与海-气相互作用密切相关,而且海洋的年代际变化也是梅雨异常变化的重要气候背景;④年代际尺度变化在全球变暖改变区域气候特征的过程中的贡献、年代际气候变化的形成及作用机制,特别是长江中下游梅雨的年代际变化的成因和机制都是仍需继续加强研究的问题。A review is made of the progress in interdecadal climate variation on the global scale, parts of China and Meiyu in the middle-lower reaches of the Changjiang River. The achievements are introduced especially in the climate researches undertaken by Chinese meteorologists. It is found： ① There exists not only clear interannual but also significant interdecadal climate variation in the global atmosphere and oceans. ② Influenced by the global climate change, multi-scale variations exist in climate of China; however, there is obvious difference between China and global interdecadal climate change.③ The variation of Meiyu in the middle and lower reaches of the Changiiang River is closely related to the interaction between coean and atmosphere; moreover, the interdecadal variation of ocean is the important background of Meiyu variation. ④ There are still many problems needing to be solved; for instance, what are the formation and influence mechanisms and contributions of interdecadal global dimate changes？ Especially the variation of Meiyu in the middlelower reaches of the Changjiang River.
