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...
El Niño vs. La Niña: What's the Difference? - Earth How
EL NINO: El Niño is the warming phase of the waters in the eastern Pacific, off the coast of South America. LA NINA: Then, La Niña is the cooling phase. Both phenomena disrupt weather and temperature around the globe. For example, they unpredictably create: El Niño and La Niña peak around Christmas time and can last 9 months or longer.

2016年1月7日 · El Niño is the name given to the occasional development of warm ocean surface waters along the coast of Ecuador and Peru. When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. El Niño normally occurs around Christmas and usually lasts for a few weeks to a few months.
El Niño and La Niña represent departures from the long-term average, or neutral, conditions. Specifically, La Niña is characterized by strong trade winds, which causes upwelling to intensify in the eastern trop-ical Pacific. With the onset of El Niño, a drop in air pressure over this region
Science of ENSO - El Niño - GLOBE.gov
El Niño and La Niña are the warm and cool phases of a recurring climate pattern across the tropical Pacific—the El Niño-Southern Oscillation, or “ENSO” for short. The pattern can shift back and forth irregularly every two to seven years, and each phase triggers predictable disruptions of temperature, precipitation, and winds.
