摘要
本文用 190 0～ 195 0年的我国实测的与内插的降水、气温资料 ,结合近代先进的统计方法建立了 190 0～ 195 0年我国东部夏季降水雨型序列 ,并将其与已有的近 4 8年 (195 1～ 1998年 )的夏季雨型序列相衔接 ,进而研究了近百年我国夏季雨带的演变规律及其与 ENSO的关系。此外 ,还研究了百年夏季雨型与大气活动中心在基本态时间尺度上的关系 ;
In the context of measured and interpolated rainfall and temperature and with the aid of a 3 discriminant function expression for discriminatory analysis an 1900 1950 sequence of east China summer rainfall pattern is established and examined,and connected to the 1951～1998 counterpart already presented to investigate the 1900 1998 evolution in rain belt movement and the frequency change features of the rainfall patterns in relation to atmospheric circulation anomaly,and ELNino events.The relationships between the rainfall patterns and intensity of atmospheric active center on the time scale of>30 year slow varying mean,called'climate base state'are investigated.The relationships between the summer rainfall in China and North Pacific oscillation are examined
