DISCUSSION AND COMPARISON OF EAST ASIA SUMMER MONSOON INDEX

摘要: 列举了四种具有代表性的东亚复季风强度指数(黄刚、严中伟定义的东亚环流异常指数HYI、张庆云等的东亚夏季风指数ZTCT、孙秀荣等的东亚海陆温差指数SCHI、施能等用海陆气压定义的东亚夏季风指数SXWI),并比较了各种指数与同斯我国气温及降水的相关分布情况,发现的反映我国夏季气温和降水异常及表征低层东亚夏季风强度方面.几种指数都有相当好的辨别能力并各具特色.此外还讨论了强.弱夏季风年我国气温及降水的异常分布特征。

Abstract: Four typical East Asia Summer Monsoon Indexes (EASMI) are enumerated and comparted here.Results show that they are good at reflecting the abnormality of rainfall and temperature of China as lower level wind fields of East Asia in summer,and the SCHI is the best comparatively.Further discussion indicates that high temperature will be seen almost all over China and there will be flood in north/south China in summer,but drought in Changjiang-Huaihe Valley in case that summer monsoon is strong,and vice verse.
