摘要
利用NCEP/NCAR逐候再分析资料,定义并计算了反映亚洲夏季风系统中各成员变化活动的指标参数,在此基础上用时滞相关分析方法,对亚洲夏季风系统诸成员与西太平洋副高面积指数的相关性进行了诊断分析,给出了夏季风系统成员之间相互影响、相互制约的基本作用过程。分析结果表明,亚洲夏季风系统成员与西太平洋副高指数之间存在着不同程度的显著时滞相关,各系统成员与西太平洋副高相互作用、互为反馈,构成了亚洲夏季风系统有机的活动整体。
In this paper, by using the five-days mean NCAR/NCEP reanalysis data for the period of 1958- 1997, some characteristic indexes for describing the Asia summer monsoon system memberships activities were defined and calculated. Based on the above works, a delayed correlation analysis method was introduced for the correlation analysis between the Asian summer monsoon system and west Pacific subtropical high area index, and some meaningful interaction processes and characteristic phenomena between them were revealed and discussed accordingly. It was shown that there exist some remarkable time-delayed correlations in various degree between the Asian summer monsoon system memberships and west Pacific subtropical high index, and they interact and have feedback with each other, playing their own roles in the whole Asian summer monsoon system.
