【摘要】 大气季节内振荡(ISO)是上世纪80年代以来大气科学的重要前沿研究课题。作者系统地回顾和总结了十多年来在大气季节内振荡(ISO)及其对其他气候系统的重要作用方面的主要研究工作和成果,尤其是新近的研究成果。主要包括热带大气ISO的基本特征和主要活动规律;中高纬度大气ISO的基本特征和活动规律,以及与热带大气ISO的主要差别;全球大气低频(30～60天)遥相关特征;大气季节内振荡的动力学机制;大气季节内振荡对南海(亚洲)夏季风爆发,以及对南海(东亚)夏季风异常的重要作用;热带大气季节内振荡与EI Nino(La Nina)的相互作用关系。更多还原

【Abstract】 Atmospheric intraseasonal oscillation (ISO) or 30-60 day oscillation has been an important frontier project in the atmospheric science since the 1980s. Some major studies and research achievements on the atmospheric intraseasonal oscillation and its important effects to other climate systems completed in the Institute of Atmospheric Physics during the last 10 years are reviewed and summarized systemati-cally in this paper, particularly some new scientific achievements. They include the fundamental features and main active regulars of the tropical ISO; the fundamental features and main active regulars of the ISO in middle-high latitudes and its differences from the tropical ISO; atmospheric low-frequency teleconnec-tion in the globe; the dynamical mechanism of the ISO; the influences of the ISO on summer monsoon onset over the South China Sea (Asia) and on summer monsoon anomaly over the South China Sea (East Asia); the interaction between the tropical ISO and El Nino (La Nina) .更多还原
