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.
