大气环流变化时南北半球、东西半球 对流层与平流层研究

本文利用 1979年 FGGEⅢ b资料研究了 1 ～ 7月对流层大气环流季节变化及变化期间南北半 球、东西半球、对流层与平流层之间的关系 . 分析指出: 对流层季节变化的量变是从 3月底、4月初开始 的 . 平流层的爆发性增温使这一量变过程提前了 ;北半球大气环流的季节变化都与南半球的环流变化相 联系 ,反之亦然. 平流层的任何一次环流变化都为对流层的季节变化提供了量的积累. 平流层是变化的 主要方面 .

Seasonal variation of global atmospheric circulation in troposphere and some relationships

In this paper, The seasonalvariationin troposphere was researched by means of FGGEⅢ b data from January to July in 1979. The relationships betw een the southern and the northern hemisphere, the eastern and the w estern hemisphere and troposphere and stratosphere w ere also studied. Main results are the following: 1) The preparatory period of seasonal variation in troposphere is in early April of 1979, the preparatory period is fulfilled ahead of time because of midw inter w arming in stratosphere; 2) The seasonal variation in the northern (southern) hemisphere is related to circulation changing in the southern (northern) hemisphere; 3) Any circulation changing in stratosphere is in preparation for the seasonal variation in troposphere.
