What is El Niño?
El Niño is a climate phenomenon caused by unusual warming of the surface waters in the central and eastern Pacific Ocean near the equator.
Normally, strong easterly winds push warm ocean water toward Asia. During El Niño, these winds become weak or may even reverse direction. As a result, warm water spreads toward the eastern Pacific Ocean.
This change affects air pressure, rainfall, temperature, and weather patterns around the world.
Main Effects of El Niño
Increase in global temperatures
Heavy rainfall and floods in some regions
Droughts and water shortages in other areas
Changes in monsoon patterns
Reduced fish population due to warm ocean water
Stronger storms and unusual weather conditions
Scientific Importance
El Niño helps scientists study climate change, ocean-atmosphere interaction, and global weather systems. It usually occurs every 2 to 7 years and can last for several months.
Simple Conclusion
El Niño is a natural climate event in which Pacific Ocean waters become warmer than normal, leading to major weather changes across the world.
