The World Meteorological Organization (WMO) is a specialized agency of the United Nations responsible for promoting international cooperation on atmospheric science, climatology, hydrology and geophysics.[2]

The WMO originated from the International Meteorological Organization, a nongovernmental organization founded in 1873 as a forum for exchanging weather data and research.[3] Proposals to reform the status and structure of the IMO culminated in the World Meteorological Convention of 1947, which formally established the World Meteorological Organization.[4] The Convention entered into force on 23 March 1950, and the following year the WMO began operations as an intergovernmental organization within the UN system.

The WMO is made up of 193 countries and territories, and facilitates the "free and unrestricted" exchange of data, information, and research between the respective meteorological and hydrological institutions of its members.[5][6] It also collaborates with nongovernmental partners and other international organizations on matters related to environmental protection, climate change, resource management, and socioeconomic development.[7]

Headquartered in Geneva, Switzerland, the WMO is governed by the World Meteorological Congress, composed of member states, which meets every four years to set policies and priorities. The Congress is led by an Executive Council led by the President, currently Abdulla Al Mandous of UAE.[8]

Governance

German meteorologist Gerhard Adrian, president of the World Meteorological Organization, in 2019

The WMO was established by the Convention of the World Meteorological Organization, signed 11 October 1947 and ratified on 23 March 1950. The Convention serves as the constituent treaty of the WMO, setting forth its purposes, governance, and general framework.

The WMO hierarchy:

  • The World Meteorological Congress, the supreme body of the Organization, determines policy. Each member state and territory is represented by a Permanent Representative with WMO when Congress meets every four years. Congress elects the President and vice-presidents of the Organization and members of the Executive Council; and appoints the Secretary-General.
  • The Executive Council (EC) implements Congress decisions.
  • The Secretariat is an eight-department organization with a staff of 200 headed by a Secretary-General, who can serve a maximum of two four-year terms.[9]

The annually published WMO Statement on the status of the World Climate provides details of global, regional and national temperatures and extreme weather events. It also provides information on long-term climate change indicators including atmospheric concentrations of greenhouse gases, sea level rise, and sea ice extent. The year 2016 was the hottest year on record, with many weather and climate extremes, according to the most recent WMO report.[10]

As of August 2023, the WMO has a membership of 193 member states and territories.[11]

Meteorological codes

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.

Recognitions received

In 2007, the Intergovernmental Panel on Climate Change (IPCC), a joint creation of the WMO and the United Nations Environment Programme (UNEP), received the Nobel Peace Prize "for their efforts to build up and disseminate greater knowledge about anthropogenic (man-made) climate change, and to lay the foundations for the measures that are needed to counteract such change."[15]

The World Meteorological Day is held annually on 23 March.[16]

Use of the International System of Units

WMO states that "the International System of Units (SI) should be used as the system of units for the evaluation of meteorological elements included in reports for international exchange."[17] The following units, which include units which are not SI units, are recommended by the WMO for meteorological observations:
