What Is the Full Form of WMO?

The full form of WMO is the World Meteorological Organization. The United Nations Specialised Department is responsible for encouraging international cooperation in the fields of atmospheric science, hydrology, climatology and geophysics. The WMO comprises 193 nations and territories and facilitates the free and unrestricted exchange of knowledge, data & research among its members of respective meteorological & hydrological institutions.

The WMO, headquartered in Geneva, Switzerland, is regulated by the World Meteorological Congress, composed of the Member States, which sets policies and goals every four years. The Congress is headed by an Executive Council controlled by the President, presently Gerhard Adrian of Germany.

History of WMO

  • The WMO developed from a non-governmental body, the International Meteorological Body, established in 1873 as a platform for the exchange of climate research and data.
  • The World Meteorological Convention of 1947, which initially proposed the World Meteorological Organisation, resulted in proposals to change the status and function of the IMO.
  • The Convention came into force on March 23, 1950, and the preceding year WMO started operation within the UN system as an intergovernmental organisation.
