The Secretariat

The Secretariat

The Secretariat, headquartered in Geneva, is headed by the Secretary-General. The Executive Office comprises the Secretary-General, Deputy Secretary-General and Assistant Secretary-General.

The Secretary-General of WMO is appointed by the World Meteorological Congress for a four-year term with a maximum tenure of 8 years. The Secretary-General is responsible for the overall technical and administrative work of the Secretariat. He manages his role by delegating substantive authority to the Deputy Secretary-General and the Assistant Secretary-General. The Secretary-General has the responsibility to appoint all Secretariat staff, including the Deputy Secretary-General and the Assistant Secretary-General, in accordance with regulations established by Congress, and with the approval of the Executive Council.




Board of Directors


In June 2019, the World Meteorological Congress approved a reform of the WMO governance and a vision for 2030 as well as other changes that called for an overhaul of the structure of the Secretariat. One of the most important changes implemented thus far is the creation of a Board of Directors. The Board, composed of senior Directors, meets once a month to discuss overall progress towards achieving departmental targets and overall organizational objectives and goals. The senior management team of Directors signs annual compacts (accountability documents) to ensure delivery on the Organization's high-level objectives.
