| World Meteorological Organization
From weather prediction to air pollution research, climate change related activities, ozone layer depletion studies and tropical storm forecasting, the World Meteorological Organization coordinates global scientific activity to allow increasingly prompt and accurate weather information and other services for public, private and commercial use, including international airline and shipping industries. WMO's activities contribute to the safety of life and property, the socio-economic development of nations and the protection of the environment.
Within the United Nations, the Geneva-based 185-Member Organization provides the authoritative scientific voice on the state and behaviour of the Earth's atmosphere and climate.
The World Meteorological Convention, by which the World Meteorological Organization was created, was adopted at the Twelfth Conference of Directors of the International Meteorological Organization (IMO), which met in Washington in 1947. Although the Convention itself came into force in 1950, WMO commenced operations as the successor to IMO in 1951 and, later that year, was established as a specialized agency of the United Nations by agreement between the UN and WMO.
The purposes of WMO are to facilitate international cooperation in the establishment of networks of stations for making meteorological, hydrological and other observations; and to promote the rapid exchange of meteorological information, the standardization of meteorological observations and the uniform publication of observations and statistics. It also furthers the application of meteorology to aviation, shipping, water problems, agriculture and other human activities, promotes operational hydrology and encourages research and training in meteorology.
WMO has eight technical commissions responsible for: aeronautical meteorology; agricultural meteorology; atmospheric sciences; basic systems; climatology; hydrology; instruments and methods of observation; and marine meteorology. Each of them meets every four years.
