| 摘 要： | 我国夏季主雨带的形成，是从上一年夏季开始的，共经历3个阶段，（1）上一年5－9月副热带西风急流的孕育期，（2）10－3月西风急流发展期，（3）西风急流为西太平副热带高压替代期（本年5－9月）－主雨带形成，在3个阶段中，北半球大气加热场上制约西风急流变化的最活跃的因子，是高，中纬地区由流状低云和冰雪盖交替进行的冷却大气过程。

| Abstract: | This paper presents that main rain-band in summer in China is formed through three climatic stages. They are (1) preparation stage of Subtropical westerly jet (from May to September); (2) Development stage of jet from October to March; (3) the jet disappearing and replacing by west pacific subtropical high from May to September. Through all the process, the most active factor for forming west jet is to cool air mass alternately by low undulates clouds and Snow-ice Covers in high and mid latitude. |
