Sir, I now understood something that around 40 years ago. Probably, when the history of ENSO will be written by the next generation of investigators, the names that may not miss are Sir Gilbert walker ( around 1920), J.Bjerknes About 1960), and Wyrtki and Quinn’s (around 1975) . I am a bit disappointed that the story now has not been fully explained. The discovery of the Pacific Ocean Warm Pool in 1987 was perhaps another addition to our efforts to understand this Warming and Cooling cycles, especially of the Eastern Equatorial Pacific ocean. Then you have not mentioned your own contribution of the TOGA ( now TAO) moorings. This may be included in the missed names. Gopinathan Krishnan is a Scientist in the 7/10 of the HDI World.
