What is El Niño? The name 'El Niño' is widely used to describe the warming of sea surface temperature that occurs every few years, typically concentrated in the central-east equatorial Pacific....

El Niñodescribes an almost year-long warming of the surface ocean in the tropical Pacific. These warming events are so extreme and powerful that their impacts are felt around the globe. During strong El Niño events, Australia and parts of Asia often receive much less rainfall than during normal years. The opposite applies to the western parts of th...
A new "flavour" of El Niño is now recognised in the tropical Pacific. This type of El Niño is characterised by warm ocean temperatures in the Central Pacific, rather than the more typical warming in the far Eastern Pacific near the South American coast, some 10,000 kilometres away. Although not as strong as the Eastern Pacific version, the Central ...
Our understanding of the new Central Pacific flavour of El Niño is hindered by the fact that El Niño events happen only every 2-7 years. So during our lifetime we can observe only a handful of events. This isn't enough to really understand Central Pacific El Niño, and whether they are becoming more common. That's why we look at corals from the trop...
This extraordinary change in El Niño behaviour has serious implications for societies and ecosystems around the world. For example, the most recent Eastern-Pacific El Niño event in 2015-2016 triggered disease outbreaks across the globe. With the impacts of climate change continuing to unfold, many of the hottest years on record also coincide with E...
This naturally occurring climate phase brings warmer weather throughout the globe and can increase the risk of extreme weather. This section explains how El Niño happens, and what affect it can have on global temperatures that are already rising due to human-caused climate change. Expand all.
Apr 16, 2024 · El Niño and La Niña episodes typically occur every two to seven years, and usually last nine to 12 months. They don't necessarily alternate: La Niña events are less common than El...
Oct 10, 2024 · El Niño and La Niña are the warm and cool phases of a natural climate pattern across the tropical Pacific known as the El Niño-Southern Oscillation, or “ENSO” for short. The pattern shifts back and forth irregularly every two to seven years, bringing predictable changes in ocean temperature and disrupting the normal wind and rainfall ...

Jan 18, 2016 · El Niño and La Niña episodes typically last 9-12 months. They both tend to develop during the spring (March-June), reach peak intensity during the late autumn or winter (November-February), and then weaken during the spring or early summer (March-June).
