A wavelet transform was made for the equatorial eastern Pacific SST anomaly time series. Results show that there are three remarkable timescale SST variations. 130-month interdecadal variation, 57-month interannual variation and 28-month quasi2-a variation. Based on this result, an El Nio event was predicted in the early part of 1997. 关 键 词：SST ANOMALY INTERANNUAL VARIATION INTERDECADAL VARIATION prediction.
