Introduction and background
Since 1961, World Meteorological Day has commemorated the coming into force on 23 March 1950 of the Convention establishing the World Meteorological Organization and the essential contribution that National Meteorological and Hydrological Services make to the safety and well-being of society. Each year, the celebrations focus on a theme of topical interest.
The World Meteorological Organization, as the successor of the International Meteorological Organization, created in 1873, has its fundamental mission to support the countries of the world in providing meteorological and hydrological services to protect life and property from natural disasters related to weather, climate and water, to safeguard the environment, and to contribute to sustainable development. This cannot happen without the necessary observations, research and operations that develop the understanding and knowledge of weather and climate.
Theme and activities of the day
A new theme and a slogan are chosen annually to improve the public's understanding of the activities of the Weather Service. The 2013 World Meteorological Day will be celebrated under the theme “Watching the Weather to Protect Life and Property”, with the subtheme: “Celebrating 50 Years of World Weather Watch”.
