摘要
用伴随相关型(ACP)分析了中国7月降水和气温与全球热带SSTA的POP(主振荡型)间的关系,得到当两个典型的传播POP处在ElNino事件发展相位时中国夏季总体呈南北旱、中间涝的形势,其中江淮流域、华中、东北东部和西北大部为降水正距平,华北、华南为负距平,降水偏多(少)时相应的气温偏低(高);当两个传播型的典型模态处于LaNina事件发展相位时情况则相反。
Associated correlation patterns (ACP) analysis of precipitation and temperature of July in China with principal oscillation patterns (POP) of the global tropical sea surface temperature anomalies (SSTA)revealed that weather is dry in south and north China and wet in central China with negative precipitation anomalies in south and north China and positive ones in Changjiang Huaihe valley, central China, the east of northeast China and most of northwest China, when the tyical propagation POP is in phase with the development of El Nino events; the situation is opposite when the typical propagation POP is in phase with the development of La Nina events. Besides, temperature anomalies are negative (positive) where the precipitation anomalies are positive (negative).
