Overview
Why World Meteorological Day matters
World Meteorological Day marks the WMO Convention and explains why weather, climate and water services matter for public safety, planning and daily life.
WMO says the day commemorates the Convention establishing the World Meteorological Organization, which came into force on 23 March 1950.
The annual theme highlights a current issue and showcases the contribution of national meteorological and hydrological services.
The day is useful for understanding warnings, observation networks, climate services and the agencies that turn data into public safety information.
