This paper analyzed the time evolution of the global 1000 hPa height anomalies related to the sea surface temperature SST) in the eastern equatorial Pacific by using ECMWF data in the period 1979–1988, in which two Pacific warm events, 1982/83 and 1986/87, are included. It is found that there are distinct evidences of eastward propagation of alternate positive/negative height anomalies not only in the tropical South Pacific but also in the tropical North Pacific. The former is associated with the Southern Oscillation (SO) and the latter is associated with the so-called Northern Oscillation (NO).
