  • The anomalies of precipitation and surface air temperature in the summer (June to August) of 1997 are simulated by use of a global spectral numerical climate model (L9R15) developed in Australia originally and modified in LASG. The purpose of this paper is to study the effect of the El Nino event that happened in that year on the anomalies. The results show that the 1997 El Nino event does have a lot of influences on the climatic anomaly in that summer, however, the effect is not the same as pointed out by statistical studies. Therefore, the effects of the El Nino events are of uncertainties. The effects of the El Nino events on the re-gional climate in China might be different due to the different SSTA distributions over the western and northwestern Pacific in the El Nino years. It is likely more important to pay attention to the SSTA distribu-tive patterns and values in the Chinese adjacent oceans. Besides the El Nino event there might be other fac-tors such as the South Asia high at the 100 hPa level which has more direct impact on the climatic anomaly in China and can be taken as another strong signal of the climatic change in the atmosphere.
