摘 要：
Based on the analysis of the Sea layer Pressure (SLP), the Outgoing Longwave Radiation (OLR) and the Zonal Wind at the lower level (850hPa) in the tropical atmosphere early in 1990's (from October, 1989 to February, 1992), the laws and characteristics of the intraseasonal oscillation are expounded in this paper. The result shows that CISK-waves are the mechanism of the intraseasonal oscillation. It is explained further that there is close relation between the intraseasonal oscillation and the E1 Nino event, the intraseasonal oscillation usually intensified before the E1 Nino event and during the E1 Nino event the intraseasonal oscillation was reduced. This paper is useful for further studying the mechanism of the ENSO.
