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.

2025年2月25日 · What is El Niño? What is La Niña? 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.

2024年4月16日 · El Niño is part of the natural climate phenomenon called the El Niño Southern Oscillation (ENSO). It has two opposite states: El Niño and La Niña, both of which significantly alter global...

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 ...

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.

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.

2023年7月13日 · El Niño is a naturally occurring phenomenon of periodic warming of sea surface temperatures in the central and eastern regions of the Pacific Ocean. La Niña is the opposite, describing...

In Spanish, El Niño means The Little Boy, or Christ Child, and La Niña means The Little Girl. While their frequency can be quite irregular, El Niño and La Niña events occur on average every two to seven years.

2020年8月20日 · We often hear the terms El Niño and La Niña thrown around in climate-related conversations, but what exactly do they refer to? This article will give a review of the cycle known as the El Niño Southern Oscillation.

2024年12月11日 · Learn the key differences between El Niño and La Niña, and how each affects U.S. weather patterns like rainfall, temperature, and hurricane activity.
