Using monthly NOAA reanalysis SST and rainfall data at 17 stations in North China during the spring(MAM) of 1951—2002,features of spring rainfall in North China and its relationships with SST are investigated.The results indicate that the frequency of negative rainfall anomaly is more than that of positive anomaly,but the intensity of positive anomaly is stronger.The interannual,interdecadal and periodic variations of spring rainfall series are obvious,and the period of rainfall is about 5 years before 1975,and about 7 years after 1975 respectively.Using correlation analyses methoe,we have found that there is a higher correlation coefficient sea area in the Indian Ocean and Eastern Equatorial Pacific,and the Indian Ocean’s SST in previous November to this year’s January significantly impacts the next spring rainfall anomaly in North China.Then it is confirmed by the SVD method that the last winter SST of the Indian Ocean is the most significant factor which affects the spring precipitation of North China.Based on composite analysis,we know the SSTA affects the atmosphere circulation and precipitation of North China by teleconnexion.
