摘　　要：大气季节内振荡(ISO:Intra-Seasonal Oscillation)主要是指时间尺度为30～60天的振荡,它是大气中最显著的一种振荡现象。作为大气的一个重要低频系统,自20世纪70年代至今的近40年中,ISO已经受到了广泛的关注,且已取得众多有意义的研究成果。ISO对调整气候变率起重要作用,对我国天气气候有着深远的影响。该文较系统地总结了近年来ISO的研究成果,主要对它的结构和活动特征、对天气气候的影响及其激发维持机制等方面进行了综述。在此基础上,对今后的一些研究重点进行了展望。The intra-srasonal oscillation of the atmosphere （ISO） mainly indicates the oscillation at a time scale of 30 to 60 days, one of the most remarkable oscillation phenomenans. As one of the most distinct low-frequency systems, ISO has been paid great attention widely, and already obtained numerous meaningful results since the 1970s. ISO plays a crucial role in adjusting climate variability and influences weather and climate of China profoundly. A systemic summary is made of the researches on ISO in the recent years, with emphases on its structure, activity characteristics, influence on weather and climate, stimulation, and maintaining mechanisms. The prospects of further studies about ISO are discussed based on those summaries.
