Main Bodies
Constituent bodies
WMO constituent bodies comprises the World Meteorological Congress, the Executive Council, Regional Associations and Technical Commissions. The World Meteorological Congress is the Organization's highest decision-making body, while the Executive Council is responsible for implementing its decisions.
Officers
The Officers of WMO are a President and three Vice-Presidents, who are also chair and vice-chairs of Congress and the Executive Council. In the performance of their duties, all officers of the Organization and members of the Executive Council act as representatives of the Organization and not of particular Members.
Regional Associations
The Regional Associations are responsible for the coordination of meteorological, hydrological and related activities within their respective regions: Region I (Africa), Region II (Asia), Region III (South America), Region IV (North America, Central America and the Caribbean), Region V (South-West Pacific), Region VI (Europe).
Technical Commissions
The Technical Commissions are comprised of leading technical experts in Earth system observations, information management and prediction in the fields of meteorology, hydrology, climatology, oceanography, atmospheric environment and other fields. These experts are are nominated by WMO Members to coordinate and develop standards and systems as per the terms of reference of each Commission. Currently, WMO has two technical commissions reviewing advances in science and technology and making recommendations on international standards to be included in the Technical Regulations, Guides and Manuals for the approval of Congress and the Executive Council.
Bureau
Together, the Officers and the Secretary-General form the Bureau, an informal consultative mechanism. Its primary role is planning, organization and coordination of the work of Congress and the Executive Council. It also reviews the implementation of the directives of Congress and the Executive Council, and facilitates consultation on a broader range of topics, including crosscutting and emerging issues, especially those requiring prompt attention.
Meetings of the Bureau are normally held twice a year, with a short meeting organized in conjunction with every regular session of Congress or Executive Council. The President, in consultation with the Secretary-General, may invite other participants with respect to consultations that may be required. The President informs Members of the agenda before Bureau meetings to enable feedback, as well as on the deliberation and outcomes following the meetings.
Other bodies
The World Meteorological Congress establishes additional bodies to advise on specific subjects.
