Based on monthly rainfall data from 160 stations in China from January 1951 to November 1987 and monthly average sea surface temperature data from January 1951 to September 1988, we analysed the effects of the zonal gradient quasi-biennial oscillations of sea surface temperature anomalies in the India and West Pacific Oceans. Some practical meaningful results were achieved. Furthermore,the possible relationship was discussed among El Nino events,zonal gradiant of sea surface temperature anomalies,and summer-summer half year rainfall in different areas over China.
