The variabilities of the western Pacific warm pool, including areas of the warm pool, positions of the gravitational center, sea surface temperature anomalies, and sea surface height anomalies are studied using Florida State University wind data. ERS -1,2, and NSCATscatterometer wind data. Reynolds optimum interpolation and historical reconstructed sea surface temperature data, and TOPEX/Poseidon sea surface height data.The relationship between the westerly wind forc ing and corresponding sea surface height and sea surface temperature responses in the tropical PacificOcean duringEl Ninoand other years are analyzed. Acommoncharacteristic for typical El Nino events is found and explainedby the westerly wind pattern.Time-frequency analysis of the Topex/Poseidon sea level deviation time series along the equator using the Empirical Mode Decomposition-Hilbert Spectrum method is also performed.
