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 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 La Niña can both have global impacts on weather, wildfires, ecosystems, and economies.

During El Niño (b), the warm pool of water moves eastward and the slope of the thermocline flattens. During La Niña (c), the warm pool moves westward and the slope of the thermocline steepens.
El Niño vs. La Niña: What's the Difference? - Earth How
“The El Niño and La Niña phenomena are part of a 3 phase cycle that occurs in the Pacific Ocean. The other phase is simply “normal” conditions.” EL NINO: El Niño is the warming phase of the waters in the eastern Pacific, off the coast of South …

Global temperature anomalies by El Niño and La Niña conditions
2025年1月7日 · The difference between a month's average sea surface temperature and the 1991–2020 average, measured in degrees Celsius. It is classified as El Niño or La Niña based on the Oceanic Niño Index, which tracks warming or cooling patterns in the central Pacific Ocean.
El Niño and La Niña - Science Notes and Projects
2023年5月31日 · El Niño and La Niña are parts of a climate cycle known as the El Niño-Southern Oscillation (ENSO). This cycle involves changes in the temperature of surface waters in the tropical Pacific Ocean, which in turn impact atmospheric pressure and wind patterns worldwide.
La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific. It represents the cold phase of the ENSO cycle. Why do El Niño and La Niña Occur? añd the atmosphere over the tropical Pacific.
