The World Meteorological Organization (WMO) is an intergovernmental organization with a membership of 191 Member States and Territories. It originated from the International Meteorological Organization (IMO), which was founded in 1873. Established by the ratification of the WMO Convention on 23 March 1950, WMO became the specialised agency of the United Nations for meteorology (weather and climate), operational hydrology and related geophysical sciences a year later. Its current Secretary-General is Petteri Taalas and the President of the World Meteorological Congress, its supreme body, is David Grimes. The Organization is headquartered in Geneva, Switzerland.
The World Meteorological Organization (WMO) is a specialized agency of the United Nations. It is the UN system's authoritative voice on the state and behavior of the Earth's atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources.
WMO has a membership of 191 Member States and Territories as of February 2014. The Convention of the World Meteorological Organization was signed 11 October 1947 and established upon ratification on 23 March 1950. WMO became the specialized agency of the United Nations in 1951 for meteorology (weather and climate), operational hydrology and related geophysical sciences. It originated from the International Meteorological Organization (IMO), which was founded in 1873.
The WMO hierarchy:
Weather, climate and the water cycle shape almost every aspect of our lives. They can be benevolent and bring abundance and well-being, but they can also be dangerous and cause great damage: weather-, climate and water-related hazards account for nearly 90% of "natural" disasters. These powerful natural forces do not recognize national borders, thus global and regional cooperation is essential. Global data are needed to understand the behaviour of the Earth’s atmosphere and its interaction with the land and oceans - whether it be to predict next week’s weather or next year’s climate, forecasters must have timely, quality-assured, standardized information coming from all corners of the world. Even the accuracy of a two-day weather forecast relies on observations from far beyond national borders. The World Meteorological Organization provides the framework for this essential international cooperation among the National Meteorological and Hydrological Services of its 191 Member States and Territories.
