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 in 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:
- The World Meteorological Congress determines the policy of WMO and meets every four years. Each Member country is represented by a Permanent Representative with WMO. The Permanent Representative should be the director of the National Meteorological or Hydrometeorological Service.
- The Executive Council (EC) implements Congress decisions and meets once a year.
- Six regional associations for addressing regional concerns (see the section on regional associations, below)
- Eight technical commissions provide technical recommendations for WMO and the national services.
- The secretariat headed by the Secretary-General coordinates the activities of WMO with a regular staff of more than 250 employees.
WMO provides a framework for international cooperation in the development of meteorology and operational hydrology and their practical application.
Since its establishment, WMO has played a unique and powerful role in contributing to the safety and welfare of humanity. Under WMO leadership and within the framework of WMO programs, National Meteorological and Hydrological Services contribute substantially to the protection of life and property against natural disasters, to safeguarding the environment and to enhancing the economic and social well-being of all sectors of society in areas such as food security, water resources and transport.
The WMO and United Nations Environment Programme (UNEP) jointly created the Intergovernmental Panel on Climate Change (IPCC). It is also directly responsible for the creation of the Global Atmosphere Watch (GAW). The IPCC has received the Nobel Peace Prize in 2007 "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change."
WMO promotes cooperation in the establishment of networks for making meteorological, climatological, hydrological and geophysical observations, as well as the exchange, processing and standardization of related data, and assists technology transfer, training and research. It also fosters collaboration between the National Meteorological and Hydrological Services of its Members and furthers the application of meteorology to public weather services, agriculture, aviation, shipping, the environment, water issues and the mitigation of the impacts of natural disasters.
WMO facilitates the free and unrestricted exchange of data and information, products and services in real- or near-real time on matters relating to safety and security of society, economic welfare and the protection of the environment. It contributes to policy formulation in these areas at national and international levels.
In the specific case of weather-, climate and water-related hazards, which account for nearly 90% of all natural disasters, WMO's programs provide vital information for the advance warnings that save lives and reduce damage to property and the environment. WMO also contributes to reducing the impacts of human-induced disasters, such as those associated with chemical and nuclear accidents, forest fire and volcanic ash. Studies have shown that, apart from the incalculable benefit to human well-being, every dollar invested in meteorological and hydrological services produces an economic return many times greater, often ten times or more.
WMO plays a leading role in international efforts to monitor and protect the environment through its programs. In collaboration with other UN agencies and the National Meteorological and Hydrological Services, WMO supports the implementation of a number of environmental conventions and is instrumental in providing advice and assessments to governments on related matters. These activities contribute towards ensuring the sustainable development and well-being of nations.
In keeping with its mandate to promote the standardization of meteorological observations, the WMO maintains numerous code forms for the representation and exchange of meteorological, oceanographical, and hydrological data. The traditional code forms, such as SYNOP, CLIMAT and TEMP, are character-based and their coding is position-based. Newer WMO code forms are designed for portability, extensibility and universality. These are BUFR, CREX, and, for gridded geo-positioned data, GRIB.
World Meteorological Day
- World Meteorological Day is held annually on 23 March.

WMO conference on climate prediction and information for decision-making
World Climate Conference-3 (WCC-3) was held from 31 August to 4 September 2009 in Geneva, Switzerland, under the auspices of WMO. Its goal was to address advancements in seasonal to multi-decadal climate predictions and to spur their applications to decision-making in socio-economic sectors, including food, water, energy, health, tourism and development sectors. The Conference aimed to contribute to the achievement of the United Nations Millennium Development Goals and broader UN climate goals through support for climate adaptation.
As of February 2014, member states of the organisation include 183 of the 193 UN members, the Cook Islands and Niue, for a total of 185 member states. Additionally there are 6 member territories, listed below.
There are 10 states that are members of the United Nations, but not of the WMO. These are: Andorra, Equatorial Guinea, Grenada, Liechtenstein, Marshall Islands, Nauru, Palau, Saint Kitts and Nevis, Saint Vincent and the Grenadines and San Marino; the most populous of these countries is Equatorial Guinea, with nearly 700,000 inhabitants. Non-members of either organisation include the Vatican City and the states with limited recognition.
The six member territories are: the British Caribbean Territories (joint meteorological organisation and membership), French Polynesia, Hong Kong, Macau, Curaçao and Sint Maarten (joint meteorological service and membership), and New Caledonia. Below is a table of all members with admission dates.

Membership by regional associations
The member states of the WMO are divided into six regional associations. The division is as follows:
|Region||Number of member states||Percentage of total||Number of member territories||Percentage of total|
The sum of member states in the regional associations is larger than the total number of member states because some nations are members to more than one regional association.
Region I (Africa)
Region II (Asia)
The member territories are:
Region III (South America)
Region III consists of the nations of South America, including France (French Guiana is an overseas region of France in South America). It has a total of 13 member states and no member territories. The member states are:
Region IV (North America, Central America, and the Caribbean)
Region IV consists of the nations of North America, Central America, and the Caribbean, including three nations based in Europe with dependencies within the region. It has a total of 25 member states and 2 member territories. The member states are:
The two member territories are:
Region V (South-West Pacific)
The member territories are:
Region VI (Europe)
States with membership in more than one region
A total of 9 member states have membership in more than one region. Two nations are members to four different regions, while seven are members of two regions. These nations, with their regions, are as follows:
- France (Regions I, III, IV, and VI)
- United Kingdom (Regions I, IV, V, and VI)
- Colombia (Regions III and IV)
- Kazakhstan (Regions II and VI)
- Netherlands (Regions IV and VI)
- Portugal (Regions I and VI)

- The following statement is given at the WMO official site at the request of the Government of the People's Republic of China: "On 11 October 1947, the representative of the Chinese Government signed the Convention of the World Meteorological Organization. After the founding of the People's Republic of China, her rightful seat in WMO was usurped by the Chiang Kai-shek clique, whose 'ratification' of the Convention of the World Meteorological Organization on 2 March 1951 was illegal and null and void. The rightful seat of the People's Republic of China was restored to her on 25 February 1972." For details, see China and the United Nations.
- Referred to by the United Nations as "The Former Yugoslav Republic of Macedonia" due to the Macedonia naming dispute.
- Both North and South Vietnam were members of the WMO prior to this date, which is the date of the reunification of Vietnam.
