    "description": "The El Niño/La Niña 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 Niño phase, followed by unusually cold water in the La Niña phase. The Advanced Very High Resolution Radiometer (AVHRR) instrument on the US National Oceanic and Atmospheric Administration's NOAA-14 spacecraft observed the changes in sea surface temperature shown here. || ",
