摘要
用３０年（１９６０～１９８９年）季平均印度洋海温距平资料和中国降水距平资料进行主振荡型分析和伴随相关分析，研究了印度洋海温３～４年时间尺度的主振荡型的时间演变及其对中国降水影响的循环过程，结果表明中国降水低频场的主要响应区域在华中，西南地区以及华北北部一带，它体现了印度洋地区热源异常通过大气内部动力过程激发的低频流型对中国降水年际变化的影响。
Based on the data of 30-year beriod (1960～1989) the principal oscillation pattern (POP) and associated correlation analysis was performed. The temporal evolutions of the POP of SST in a time scale of 3～4 years over Indian Ocean and its influence on low frequence field of the rainfall in China have been examined. It is pointed out that the major response regions appear in the central, southwest and north China, that refleotes the effect of anomally flow patterns exicted by the anomaliy heating in Indian Ocean through atmospheric internal dynamic orocess. On the precipitation in China.
