摘要
本文采用自然正交展开和典型相关分析相结合的方法建立了恢复亚欧大气环流场的统计模式,通过对权重系数场的恢复进而达到恢复大气环流场的目的。并用1951—1980年的实测资料对所恢复的1月、4月、7月、10月同期500hPa月平均高度距平场的效果进行了考察,为恢复历史时期的亚欧大气环流场提供了一定的参考信息。
Through natural orthoginal expansion and typical correlation anal-ysis, a statistical model for restoring the Eurasia general circulationfield is established. For this purpose, the weight coefficient field isalso restored.By using the real-time observational data from 1951 to 1980,examination is made on the effects of the restored 500hPa monthlyaverage height anomaly field in January, April, July and October of thesame years so that a certain reference information is provided for restor-ing the Eurasian general circulation field in the historic periods.
