El Niño, La Niña and neutral conditions seen different ways
- Equatorial sea level & upper ocean temperatures - seen in 3-D Latitude-Longitude-depth plots
- Equatorial surface temperatues - seen in Latitude-Longitude plots
- Pacific Ocean temperature anomalies (deviations) - seen in Latitude-Longitude plots
- Schematic diagrams explain the warm pool and the thermocline during El Niño, La Niña and neutral conditions

- YouTube videos:
- Evolution of the 2009-2010 El Niño, the strongest "Central Pacific" El Niño in the past 3 decades, with maximum warming in the central equatorial Pacific (vs the classic El Niño, like 1997-1998, with maximum warming in the eastern tropical Pacific).
