Established in 1950, WMO became the specialised agency of the United Nations for meteorology ( weather and climate ), operational hydrology and related geophysical sciences.

He was one of the first to see the need for international cooperation, and in 1873 became the first chairman of the International Meteorological Organization, a precursor of the World Meteorological Organization ( WMO ).

In this capacity he spent some years in Antarctica and in Malta and North Africa and became a Member of the WMO Working Group on Climate Fluctuations.

The World Meteorological Organization ( WMO ) is a specialized agency of the United Nations.

The United Nations, its subsidiary bodies, thirteen of the specialized agencies ( ILO, FAO, UNESCO, WHO, ICAO, UPU, ITU, WMO, IMO, WIPO, IFAD, UNDIO, and UNWTO ), and one related body ( IAEA ) are part of the United Nations common system of salaries, allowances, and benefits administered by the International Civil Service Commission.

He worked as an expert consultant to a wide range of specialized United Nations agencies including UNESCO, World Meteorological Organization ( WMO ), United Nations Environment Programme ( UNEP ), and the Food and Agriculture Organization ( FAO ).

It takes advice on issues needing multidisciplinary expertise from the Joint Group of Experts on Scientific Aspects of Marine Environmental Protection ( GESAMP ) which is composed of specialized experts nominated by the IMO, FAO, UNESCO, IOC, WMO, WHO, IAEA, UN, and UNEP.

The WMO and United Nations Environment Programme ( UNEP ) jointly created the Intergovernmental Panel on Climate Change ( IPCC ).

He has been Chair or co-chair of other international scientific assessments, including the IPCC Working Group II, the United Nations Environment Programme / World Meteorological Organization ( UNEP / WMO ), and the UNEP Global Biodiversity Assessment.

: Internationally, the Intergovernmental Panel on Climate Change ( IPCC ), under the auspices of the United Nations ( UN ), World Meteorological Organization ( WMO ), and the United Nations Environment Program ( UNEP ), is the most senior and authoritative body providing scientific advice to global policy makers.

ECMWF has dramatically improved the accuracy and reliability of weather forecasting, working in collaboration with Member and Co-operating States, the European Union and partners such as the World Meteorological Organization ( WMO ), the European Organisation for the Exploitation of Meteorological Satellites ( EUMETSAT ) and the European Space Agency ( ESA ).

* Eight technical commissions provide technical recommendations for WMO and the national services.

WMO provides the framework for such international cooperation.

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.

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.

Newer WMO code forms are designed for portability, extensibility and universality.

The symbol used on the map for each of these levels at a particular observation time will be for the genus, species, variety, mutation, or cloud motion that is considered most important according to criteria set out by the World Meteorological Organization ( WMO ).

It is being sponsored by the International Council for Science ( ICSU ) the World Meteorological Organization ( WMO ).

Most weather agencies use the definition for sustained winds recommended by the World Meteorological Organization ( WMO ), which specifies measuring winds at a height of for 10 minutes, and then taking the average.

In 1990, WMO launched the idea of an International Conference on Water and Climate that would be held as a preparatory meeting for the Rio Summit on the environment and development.

The Met Office's Global Model forecast has consistently been in the top 3 for global weather forecast performance over the past few decades in independent verification to WMO standards.

At the top of the mountain ( where the weather has been measured since 1915 ) is a weather observatory that has been in operation since 1937 and carried on by the German meteorological service ( WMO code number: 10908 ).

The members of the WMO are representatives of their respective countries, not their weather services.

SYNOP ( surface synoptic observations ) is a numerical code ( called FM-12 by WMO ) used for reporting weather observations made by manned and automated weather stations.

The world climate conferences are a series of international meetings, organized by the World Meteorological Organization ( WMO ), about global climate issues.

The outcomes formed part of WMO input to the 2009 UNFCC COP-15 meeting for climate mitigation in Copenhagen in the December following WCC-3.
