摘要
本文利用1983年5～6月ECMRWF资料,从1983年亚洲夏季风爆发过程的诊断分析中,就印度季风和南海季风的相对独立性和互相联系性作了探讨。结果表明,印度季风区和南海季风区具有独立的季节变化中心;印度季风和南海季风在季风爆发的时间上、季风爆发的物理机制上、季风爆发过程中风、温湿场的相互关系上均有明显差异;季风爆发后两个子季风区的季风环流的演变逐步趋向同步,维持季风及季风区温湿场的物理过程也趋向一致,平均垂直运动在联系两个子季风中起了重要作用。
The onset process of Asia summer monsoon during 1983 is analysed and the independence and the relation between India monsoon and South-China sea monsoon are studied by using ECMRWF data. The results show that there are independent centers of seasonal variation in India monsoon region and in Sonth-China sea monsoon region respectively; the beginning dates, the physical mechanisms of monsoon onset and the relation between wind and temperature or humidity during the onset process in India monsoon region are different from those in South-China sea monsoon region; after the onset, the variations of the monsoon circulations and the physical processes which maintain monsoon and its temperature and humidity fields in the tow sub-monsoon reginos tend to consist with each other; vertical movement plays an important role in the relation between the two sub-monsoons.
