Spanish for "The Niño"
The following reports and resources are excellent starting points for grasping the fundamental aspects of ENSO, and opportunities to delve deeper into specific facets of this important and fascinating phenomenon.
El Niño and anthropogenic climate change aren't the same thing, and climatologists stress each phenomenon’s individual effects on weather patterns and occurrences shouldn't be conflated.
An El Niño event can alter economic fortunes worldwide, particularly in agriculture. But other industries can be affected too, including energy, forestry, sales and transportation.
An El Niño winter with warmer temperatures and possibly less precipitation than average could pose a challenge for some Wisconsin recreation and tourism businesses, although many already have been adapting to uncertain winters with less snow.

The El Niño that started in early 2015 and is affecting global weather patterns could be less than idyllic for Wisconsin wildlife adapted to snowy conditions.
ENSO in 2014
The El Niño Southern Oscillation is an irregular cycle in which changing temperatures of surface waters in the tropical Pacific Ocean can result in major impacts on global weather patterns.
ENSO sea level comparison, 1997 and 2015
The El Niño of 1997-98 was historic, but no two ENSO events are alike, nor are their weather effects in any given location, thanks to differences in how Pacific Ocean waters warm.
ENSO in 1997 and 1998
The 1997-98 El Niño event stands out both for its intensity and how it brought the ENSO phenomenon to public attention.

Each El Niño event has a different effect on weather conditions on both global and local scales. These differences in large part depend on how a given El Niño develops.
