Abstract: In this paper,the relationships between the sea surface temperature of Equatorial Eastern Pacific and the air temperature of South China in winter and spring were analyzed,and the possible physical processes were discussed. The results show that the ENSO events do have some effects on the air temperature of south China in winter and spring. It seems to be completed throngh the influence of the marine anomaly heat transfer from Equatorial Eastern Pacific on the Hadley circulation and the westerlies in Northern Hemisphere winter.
