ENSO Phenomenon

ENSO Phenomenon

The El Niño-Southern Oscillation (ENSO) is a major climate pattern that significantly influences global weather patterns. It involves fluctuations in sea surface temperatures and atmospheric pressure across the Pacific Ocean.

• El Niño
  • Warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean.
  • Weakening trade winds.
  • Changes in ocean circulation.
  • Impacts: Increased rainfall in some regions, droughts in others, and altered weather patterns globally.
• La Niña
  • Cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean.
  • Stronger trade winds.
  • Impacts: Increased rainfall in some regions, droughts in others, and altered weather patterns globally.
• Impacts of ENSO
  • Weather Extremes: Increased frequency and intensity of extreme weather events such as floods, droughts, and heatwaves.
  • Impacts on Ecosystems: Disruptions to marine ecosystems, affecting fisheries and other marine life.
  • Socioeconomic Impacts: Impacts on agriculture, fisheries, and human health.
• Predicting ENSO
  • Scientists use various methods, including monitoring sea surface temperatures, atmospheric pressure, and ocean currents, to predict ENSO events.
  • Accurate predictions can help communities prepare for potential impacts and mitigate potential risks.
