El Niño & La Niña (El Niño-Southern Oscillation) - NOAA …
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.
El Niño and La Niña - National Oceanic and Atmospheric Administration
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.
What are El Nino and La Nina? - NOAA's National Ocean Service
El Niño and La Niña are two opposing climate patterns that break these normal conditions. Scientists call these phenomena the El Niño-Southern Oscillation (ENSO) cycle. El Niño and …
El Niño–Southern Oscillation - Wikipedia
El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variation in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some semblance of cycles. The occurrence of …
El Nino Index Dashboard: NOAA Physical Sciences Laboratory
El Niño Index Dashboard ENSO is a phenomenon which extends over large spatial area and can have a different seasonal evolution from event to event. The different patterns have implications for climate impacts both locally and at a distance. The following indices all help characterize ENSO but at different locations and time scales.
