With EOF,REOF and SVD,the spatial anomaly features of both the North Pacific SSTA and the spring rainfall in West China and the correlations are studied by using the pricipitation data in spring for the period 1960~1994 from 89 observational stations and the North Pacific sea surface temperature of 286 grid points in the area of 10°S~50°N,120°E~80°W in autumn.The results show that the first six rotated loading vector fields represent six principal SSTA areas,among which the east equatorial Pacific is the most sensitive signal area.There are five principal spring rainfall anomerly areas in Northwest China:the Eastern Plateau,the eastern part of Northweat China,the Northern Xinjiang,the Qinghai Plateau,the Southern Xinjiang-Hexi Corridor.Clear teleconnections really exist between the SSTA in east equatorial Pacific in autumn and the next spring rainfall in Northweat China.When the SSTA is high(low),that is to say,when El Niño(La Niña) appears in autumn,Northwest China is wet(dry) in the next spring.The cases are same in the next March and May.But the wet(dry) center in March is near Xining,Qinghai province;while in May,Pingliang,Gansu province,is the center.In April,the case is contrary with March and May.
