World Meteorological Organization (WMO), Headquarters, Members

The World Meteorological Organization (WMO) is an intergovernmental organisation that promotes global cooperation in meteorology and related Earth-system sciences. Its work covers weather, climate, hydrology, environmental monitoring, forecasting, data exchange and early-warning systems. 

WMO provides a common international framework that enables national meteorological and hydrological services to share observations, scientific knowledge and technical expertise. Through this cooperation, it supports better weather and climate services, strengthens disaster preparedness and helps countries respond to environmental risks. Its activities are particularly important for improving forecasting, protecting lives and property, and supporting climate-resilient development worldwide.

WMO Full Form

The full form of WMO is World Meteorological Organization. It is a specialised agency of the United Nations dealing with weather, climate, water and associated environmental sciences. The organisation became a United Nations (UN) specialized agency in 1951, following the entry into force of its Convention in 1950.

World Meteorological Organization (WMO) History

The history of WMO is closely connected with the development of international cooperation in meteorology during the 19th century. Its institutional roots can be traced to the International Meteorological Organisation (IMO), established in the aftermath of the 1873 Vienna International Meteorological Congress.

• Vienna Congress (1873): The 1873 Vienna International Meteorological Congress called for an international mechanism to facilitate the exchange of weather information across national boundaries.
• IMO Formation (1879): The Permanent Meteorological Committee completed the proposed rules and statutes at Utrecht in 1878, leading to IMO's establishment during the 1879 Rome Congress.
• International Meteorological Committee: The Rome Congress established the International Meteorological Committee to promote international cooperation, meteorological research, uniform observations, reporting practices, and systematic data exchange.
• World Meteorological Organisation Established: Following World War 2, efforts intensified to establish a stronger intergovernmental framework. The WMO Convention entered into force on 23 March 1950, replacing IMO and strengthening global meteorological cooperation.
• UN Specialised Agency (1951): In 1951, WMO became a specialised agency of the United Nations, expanding international cooperation in meteorology, hydrology, and related geophysical sciences.

World Meteorological Congress

The World Meteorological Congress is the supreme decision-making body of the WMO and comprises representatives of all its Members. It meets once every four years to determine the organisation's overall policies, approve strategic and long-term plans, adopt regulations, and elect key officials. It provides the overarching direction for international cooperation in weather, climate, water, and related sciences.

WMO Executive Council

The Executive Council serves as the executive body responsible for implementing decisions adopted by the World Meteorological Congress. It generally meets annually in Geneva to review WMO programmes, coordinate their implementation, and oversee financial and administrative matters.

WMO Regional Associations

The Regional Associations coordinate WMO activities according to the specific meteorological, hydrological, and climatic requirements of different geographical regions. There are six Regional Associations, covering Africa, Asia, South America, North America, Central America and the Caribbean, Southwest Pacific, and Europe.

WMO Secretariat

The WMO Secretariat is the organization's permanent administrative, operational, and technical body, headquartered in Geneva, Switzerland. It supports the work of the Congress, Executive Council, Regional Associations, and Technical Commissions. The Secretariat operates under the leadership of the WMO Secretary-General.

WMO Technical Commissions

The Technical Commissions provide scientific and technical expertise to support WMO programmes and international cooperation. Major commissions include the Commission for Weather, Climate, Water and Related Environmental Services and Applications (SERCOM) and the Commission for Observation, Infrastructure and Information Systems (INFCOM).

World Meteorological Organization (WMO) Projects

The WMO projects programme focuses on strengthening the ability of members to provide weather, climate and water services. Projects are implemented at national and regional levels and are designed around specific needs and challenges.

Important examples include:

• Climate Risk and Early Warning Systems (CREWS): Supports countries in strengthening early-warning and early-action capabilities.
• Early Warnings for All (EW4All): Supports the broader global objective of protecting people from hazardous weather, climate and water events through effective multi-hazard warning systems.
