Abstract
With EOF, REOF, period analysis and Morlet wavelet analysis, the spatial anomaly features, time evolution rules and period variations for autumn rainfall anomaly in northwest China and the reiationships between the rainfall anomaly and the middl east Pacific SSTA are studied in detail by using the autumn pricipitation data for the period of 1960~1997 from 63 observational stations and the SSTA in the area of NINOC. Some significant results are obtained.
