How does El Niño influence global weather patterns?.
El Niño is a climate phenomenon characterized by the warming of ocean surface temperatures in the central and eastern Pacific. This warming disrupts normal weather patterns, resulting in various global impacts.
Key Facts
- El Niño occurs every 2 to 7 years, typically lasting 9-12 months.
- It affects global temperatures, contributing to an average increase of 0.2°C to 0.5°C during events.
- El Niño is linked to heavier rainfall in the southern United States and droughts in Australia and Southeast Asia.
- The 1997-1998 El Niño was one of the strongest recorded, causing significant global climatic disruptions.
Examples or Use Cases
- Increased rainfall in California can lead to floods and landslides during El Niño years.
- Conversely, countries like Indonesia often experience severe droughts and wildfires.
FAQs
- What causes El Niño? El Niño is caused by weak trade winds and changes in ocean temperatures.
- How does it affect agriculture? El Niño can lead to crop failures due to altered rainfall patterns.
