Notes

  • The World Meteorological Organisation (WMO) forecasts that the current El Nino phenomenon will persist through February 2027 with near 100% certainty.
  • The phenomenon is driven by exceptionally warm Pacific Ocean temperatures and may become the strongest ever recorded.
  • El Nino is defined as a periodic warming of sea surface temperatures in the eastern Pacific caused by the weakening of trade winds.
  • It typically occurs every two to seven years and lasts up to 12 months.
  • El Nino impacts global climate patterns, leading to significant shifts in rainfall and temperature, including increased risks of droughts and typhoons.
  • The WMO is prioritizing early warning systems and preparedness efforts to mitigate the impact on member states.
