This animation shows the onset of the very strong 1997 El Nino, followed by its collapse and replacement by La Nina. Anomalously warm waters slosh across the Pacific in late 1997 as El Nino begins and the equatorial trade winds diminish in strength. In May 1998, the El Nino event disperses and is rapidly replaced by its reciprocal phenomenon, La Nina, with anomalously cold water along the eastern ... Full description.

The El Nino-La Nina event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. A strong upwelling of unusually warm water was observed in the Pacific Ocean during the El Nino phase, followed by unusually cold water in the La Nina phase. The Advanced Very High Resolution Radiometer (AVHRR) instrument on the US National Oceanic and Atmospheric Administrations ... Full description.
