The 1997-98 El Nino was, by some measures, the strongest on record, with major climatic impacts felt around the world. A newly completed tropical Pacific atmosphere-ocean observing system documented this El Nino from its rapid onset to its sudden demise in greater detail than was ever before possible. The unprecedented measurements challenge existing theories about El Nino-related climate swings and suggest why climate forecast models underpredicted the strength of the El Nino before its onset. 
Evolution of the 2002/03 El Niño*
An El Nino of moderate intensity developed in the tropical Pacific in 2002/03. This event, though not as strong as the 1997/98 El Nino, had significant impacts on patterns of weather variabilityExpand
The 1918/19 El Niño
AbstractEl Nino is widely recognized as a source of global climate variability. However, because of limited ocean observations during the early part of the twentieth century, little is known about ElExpand

The recent El Nino has been by most measures one of the most extreme, and there have been several papers on its thermal signature and associated wind field. There has also been wide coverage of theExpand
Dynamic evolution of the 1997–1999 El Niño–La Niña cycle in the southern California Current System
Abstract The development of the strongest El Nino event on record in the equatorial Pacific in 1997–1998 and the rapid transition to strong La Nina conditions in 1998–1999 had a large impact on theExpand
Equatorial waves and the 1997–98 El Niño
New measurements and model results highlight the role of equatorial oceanic wave processes in affecting the evolution of the 1997–98 El Nino in ways not fully anticipated by delayed oscillatorExpand
What Caused the Onset of the 1997-98 El Nino ?
Abstract There has been intense debate about the causes of the 1997–98 El Nino. One side sees the obvious intense westerly wind events as the main cause for the exceptional heating in summer 1997,Expand
Mechanisms of the 1997–1998 El Niño–La Niña, as inferred from space‐based observations
[1] The intensity of the 1997 El Nino and the 8°C sudden drop in sea surface temperature (SST) around 0°–130°W during the turn into La Nina in 1998 were a surprise to the scientific community. ThisExpand

TLDR
These features, revealed by the multi-year TOPEX altimeter data, may serve as new clues to improve the understanding of El Nino formation, and may also contribute to its future prediction. Expand
