1. El Niño Introduction. Audio volume and few illustrations are updated from V1.2 El Niño Visualization Explain three terms, Upwelling, thermocline, and East-West Asymmetry. Those terms are necessary to explain El Nino phenomena. The high definition versions of this video can be found at http://www.duke.edu/~ts24/ENSO/ 3D Globe image in this animation is from CSIRO. Explain Wind - Gravity balance at Equator. Kelvin wave, and water flow. During El Nino, Peru condition is different from normal, but upwelling continues. Explain why anchovy decreased? I think this chapter is most important for this El Nino animation. Describe how El Nino recovers from unusual status. Videos also found at http://www.duke.edu/~ts24/ENSO/ Sakagami, T., R.B.
