World Meteorological Organization. It is a specialized agency of the United Nations dedicated to international cooperation and coordination on the state and behaviour of the Earth's atmosphere, its interaction with the oceans, the climate it produces, and the resulting distribution of water resources. Established in 1950, it succeeded the International Meteorological Organization founded in 1873. The organization facilitates the free and unrestricted exchange of meteorological data and information between its members, supports research and training, and works to standardize observations to ensure uniform global practices.

History

The origins trace back to the 1873 Vienna International Meteorological Congress, which established the International Meteorological Organization. This non-governmental body coordinated weather observation networks and maritime meteorology for decades. Following World War II and the creation of the United Nations, the need for a formal intergovernmental body led to the 1947 World Meteorological Convention. The organization officially began operations on 23 March 1950, eventually becoming a specialized agency of the United Nations in 1951. Key milestones include its role in the International Geophysical Year and launching the World Weather Watch in 1963. Its work has increasingly focused on climate change, notably through assessments by the Intergovernmental Panel on Climate Change.

Structure and governance

The supreme body is the World Meteorological Congress, which convenes every four years with delegates from all member states. The Executive Council implements congress decisions and meets annually. Six regional associations address specific geographical issues, such as those for Africa and Asia. Eight technical commissions develop standards and guidelines for areas like aerology and hydrology. The permanent secretariat, headquartered in Geneva, is led by the Secretary-General, currently Celeste Saulo. The current President of the organization is Abdulla Al Mandous. Key partners include the World Health Organization and the International Civil Aviation Organization.

Functions and programs

Its core functions include setting international standards for meteorological observations, promoting the exchange of real-time data, and fostering capacity development in developing countries. Major programs monitor global systems through initiatives like the World Weather Watch and the Global Atmosphere Watch. It provides critical support for aviation safety, agriculture, and disaster risk reduction. The organization also coordinates global research on topics such as tropical cyclones and polar meteorology, and plays a key role in implementing the Paris Agreement through climate services.

World Weather Watch

The World Weather Watch is the core program that integrates observing systems, telecommunication networks, and data-processing centers worldwide. It relies on the Global Observing System, which includes thousands of land stations, Arctic and Antarctic outposts, weather buoys, and satellites like the Meteosat series. The Global Telecommunication System facilitates the rapid exchange of data between national centers such as the Japan Meteorological Agency. This global infrastructure supports daily weather forecasting, severe typhoon warnings, and services for sectors including shipping and energy.

Global Atmosphere Watch

The Global Atmosphere Watch program monitors changes in atmospheric composition, including greenhouse gases, ozone layer depletion, and air pollution. It coordinates a network of stations from Mauna Loa Observatory in Hawaii to the South Pole. Data from this program are fundamental to assessments by the Intergovernmental Panel on Climate Change and inform international treaties like the Montreal Protocol. The program tracks long-term trends in carbon dioxide and methane, studies atmospheric aerosols, and supports research on UV radiation and acid rain.

Publications and reports

It publishes authoritative technical reports, manuals, and guidelines, such as the International Cloud Atlas. The annual WMO Statement on the State of the Global Climate is a key report cited by global media and policymakers. Other significant publications include bulletins on the Antarctic ozone hole, reports from the World Climate Research Programme, and data from the Global Climate Observing System. These documents provide essential information for scientists, the United Nations Framework Convention on Climate Change, and national agencies like the National Oceanic and Atmospheric Administration.

Member states and territories

The organization has 193 member states and territories, encompassing almost all United Nations members, including recent members like South Sudan. Membership also includes territories with distinct meteorological services, such as the British Caribbean Territories. All members maintain designated National Meteorological and Hydrological Services, like the Meteorological Service of Canada and the Australian Bureau of Meteorology. These members collaborate through regional associations covering areas like South America and Europe, ensuring global participation in its governance and programs.
