2025年2月25日 · By influencing global temperatures and precipitation, the El Niño/Southern Oscillation (ENSO) significantly impacts Earth’s ecosystems and human societies. El Niño and La Niña are opposite extremes of the ENSO, which refers to cyclical environmental conditions that occur across the Equatorial Pacific Ocean. These changes are due to natural interactions …

2016年2月2日 · The TAO story: Developing an El Nino observing system Real-time data from moored ocean buoys improves detection, understanding and prediction of El Niño and La Niña. (NOAA) Today NOAA and the Japan Agency for Marine-Earth Science Technology are leading an effort involving scientist from many other nations to improve this early warning system.

Transcript NARRATOR: Warmer or colder than average ocean temperatures in one part of the world can influence weather around the globe - boggles the mind, right? Here’s how it works. During normal conditions, trade winds, which blow from east to west, push warm surface waters towards Asia, piling it up in the western Pacific. In some years though, the trade winds …

Transcript NARRATOR: El Niño and La Niña are periodic weather patterns resulting from interactions between the ocean and the atmosphere in the tropical Pacific Ocean. Ocean temperatures indicate the presence of El Niño and La Niña, which sometimes lead to extreme weather in many parts of the United States. NOAA climatologists closely track the …

2023年9月26日 · Further research found that El Niño is actually part of a much larger global variation in the atmosphere called ENSO (El Niño/Southern Oscillation). The Southern Oscillation describes changes in air pressure patterns in the Southern Pacific Ocean between Tahiti, in the middle of the southern Pacific Ocean, and Darwin, Australia, to the west. Normally, lower …
