The World Meteorological Congress is the supreme body of WMO. The Executive Council implements its decisions, while six Regional Associations are responsible for the coordination of meteorological, hydrological and related activities within their respective Regions. In addition, eight Technical Commissions establish methodologies and procedures and make recommendations to the Executive Council and the Congress.


World Meteorological Congress

World Meteorological Congress assembles delegates of Members once every four years to determine general policies for the fulfilment of the purposes of the Organization; to consider membership of the Organization; to determine the General, Technical, Financial and Staff Regulations; to establish and coordinate the activities of constituent bodies of the Organization; to approve long-term plans and budget for the following financial period; to elect the President and Vice-Presidents of the Organization and members of the Executive Council; and to appoint the Secretary-General. 

The duties of the President and Secretary General of the Organization are defined in the WMO General Regulations contained in Basic Documents No. 1 (WMO publication number 15), which also contains the texts of the WMO Convention; the General, Staff and Financial Regulations; the text of the Agreement between the UN and WMO; the Convention on the Privileges and Immunities of the Specialized Agencies; and the agreement, plan of execution and protocol concluded between the Swiss Federal Council and WMO governing the latter's status in Switzerland.

WMO Bureau

The Bureau is an informal consultative mechanism to advise the President and facilitate the discharge of his mandate.

Governance Reform

Established in 1950, WMO recognizes the need to continuously adapt to a rapidly changing world. The need for regular reform is being driven by environmental degradation, resource constraints, increased competition, technological advances, and other forces. The goal for WMO is to remain fit-for-purpose and to become more and more nimble and cost-effective.

Congress Election Process

One of the primary duties of Congress is to elect the President and Vice-Presidents of the Organization and members of the Executive Council other than the presidents of the regional associations (who are Ex-Officio Members of the Executive Council).

Technical Commissions

There are eight Technical Commissions responsible for studying meteorological and hydrological operational systems, applications and research. They establish methodology and procedures and make recommendations to Executive Council and Congress.
