World Meteorological Organization (WMO)

WMO is a United Nations specialized agency for meteorology (weather and climate), operational hydrology, and related geophysical sciences. Established in 1950, it coordinates global weather observation, data sharing, and climate monitoring.

Key details
  • WMO coordinates the Global Climate Observing System (GCOS), including networks of weather stations, ocean buoys (Argo float network, TAO/TRITON buoy array in the Pacific), and satellites that provide the SST data underpinning ENSO forecasts.
  • WMO publishes regular ENSO updates — typically every three months — based on ensemble forecasts from multiple national meteorological services.
  • The Global Seasonal Climate Update (GSCU), issued by WMO, is the primary international reference for seasonal climate outlooks.
  • WMO's 2023 El Nino advisory correctly forecast the 2023-24 event, which became the strongest on record at the time.
