How will climate change change El Niño and La Niña?
In a warming climate, rainfall extremes are projected to shift eastward along the equator in the Pacific Ocean during El Niño events and westward during extreme La Niña events. Less clear is the potential evolution of rainfall patterns in the mid-latitudes, but extremes may be more pronounced if strong El Niños and La Niñas increase in ...
El Niño & La Niña (El Niño-Southern Oscillation) - NOAA Climate…
2024年11月14日 · 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 ...
Global impacts of El Niño and La Niña | NOAA Climate.gov
2016年2月9日 · The disruptions of tropical Pacific sea surface temperature and rainfall that occur during the climate pattern called "ENSO" trigger a cascade of global side effects. These maps show how El Niño and La Niña affect seasonal climate around the world.
El Niño and La Niña: Local and global effects | Climate Central
2023年2月8日 · Since 2020, the planet has been in a cold phase (La Niña) of the El Niño-Southern Oscillation (ENSO) climate pattern. But that’s about to change. Heading into spring 2023, we’re approaching a...
What is El Niño and how is it influenced by climate change?
El Niño and La Niña are two phases of the naturally occurring climate phenomenon called the El Niño–Southern Oscillation (ENSO), which leads to the most dramatic year-to-year variation of Earth’s climate. El Niño is characterised by warmer global temperatures, while La …

Schematic diagrams of El Niño, Normal and La Niña conditions. The left side of each diagram is the western Pacific Ocean, near Asia, and the right side is the eastern Pacific Ocean, near South America. Red/orange colors indicate warm ocean surface temperatures, yellow/greenish colors indicate cooler temperatures.
What are El Niño and La Niña, and how do they change the weather? - BBC
2024年4月16日 · What are El Niño and La Niña, and how do they change the weather? The El Niño weather phase, which began in summer 2023, has now come to an end, the Australian Bureau of Meteorology says. It...
El Niño Southern Oscillation (ENSO) - World Health Organization …
2023年11月9日 · El Niño Southern Oscillation (ENSO) is one of the most important sources of annual global climate variability, second only to the earth–sun relationship that drives the seasons. El Niño and its counterpart La Niña are associated with characteristic patterns of rainfall and temperature, which can include extreme events such as flooding and ...
El Niño and La Niña - National Oceanic and Atmospheric Administration
2015年7月1日 · An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
El Niño and La Niña: Frequently asked questions - NOAA Climate…
2016年1月18日 · El Niño (the warm phase) and La Niña (the cool phase) lead to significant differences from the average ocean temperatures, winds, surface pressure, and rainfall across parts of the tropical Pacific. Neutral indicates that conditions are near their long-term average.
