Established 11 Oct 1947, Washington DC (USA), on signature of a convention on behalf of 42 states at conclusion of 12th Conference of Directors of International Meteorological Organization (IMO), an international nongovernmental organization founded in 1873. IMO continued to function on an interim basis, pending formal establishment of the World Meteorological Organization which took place, 23 Mar 1950, on coming into force of the IMO Convention. Resources and obligations of IMO were transferred to WMO, 4 Apr 1951, at 1st Congress. Agreement between the United Nations and WMO approved, 20 Dec 1951, by UN General Assembly, established WMO as a specialized agency of United Nations (UN) within United Nations System, linked to United Nations Economic and Social Council (ECOSOC). Statutes registered in 'UNTS 1/998' and 'ICAO 840'.

'WMO Programmes':

WMO Applications of Meteorology Programme (AMP) facilitates the application of meteorology, in all countries, for the attainment of national social, economic and cultural goals and sustainable development. It includes: 'Public Weather Services Programme'; 'Agricultural Meteorology Programme'; 'Aeronautical Meteorology Programme'; 'Marine Meteorology and Related Oceanographic Activities Programme'.

WMO Atmospheric Research and Environment Programme (AREP) coordinates and stimulates research on the composition of the atmosphere, the physics and chemistry of clouds, weather modification techniques, tropical meteorology processes and weather forecasting, focusing on extreme weather events and socio-economic impacts. It also coordinates the global monitoring of greenhouse gases, the ozone layer, major atmospheric pollutants and urban environment and meteorological studies. It includes: 'Global Atmosphere Watch (GAW)', set up June 1989; 'World Weather Research Programme'; 'THORPEX'; 'Tropical Meteorology Research Programme'; 'Physics of Clouds and Weather Modification Research Programme'. Scientific institutions include:

 • WMO World Ozone and Ultra-Violet Data Centre (WOUDC);

 • WMO World Data Centre for Greenhouse Gases (WDCGG);

 • WMO World Data Centre for Aerosols, Ispra;

 • WMO World Radiation Data Centre, St Petersburg (WRDC);

 • WMO World Data Centre for Aerosol Optical Depth, Asheville NC (activities currently suspended).

WMO Education and Training Programme assists members, in particular in developing countries and countries with economies in transition, in obtaining specially educated and trained to internationally agreed standards in order to carry out the activities and operations of National Meteorological and Hydrological Services required at the global, regional and national levels for the effective provision of meteorological and hydrological services in support of sustainable development of member countries.

Global Climate Observing System (GCOS), established in 1992, aims to ensure that the observations and information needed to address climate-related issues are obtained and made available to all potential users. It is co-sponsored by WMO, IOC, UNEP and ICSU. It is intended to be a long-term, user-driven operational system capable of providing the comprehensive observations required for monitoring the climate system, for detecting and attributing climate change, for assessing the impacts of climate variability and change, and for supporting research toward improved understanding, modelling and prediction of the climate system. It builds upon, and works in partnership with, other existing and developing observing systems.

WMO Hydrology and Water Resources Programme (HWRP) provides for the collection and analysis of hydrological data as a basis for assessing and managing freshwater resources, for example, for human consumption, sanitation, irrigation, hydropower production and water transport, and for flood forecasting system and the prediction of droughts. It includes: Programme on Basic Systems; Programme on Applications and Forecasting; Programme on Sustainable Development of Water Resources; Programme on Capacity Building in Hydrology and Water Resources; Programme on Water-related Issues; Associated Programme on Flood Management; World Hydrological Cycle Observing System; Hydrological Operational Multipurpose System.

WMO Disaster Risk Reduction Programme (DRR) develops an organization-wide coordinating framework to enhance further WMO's contributions to the natural disaster risk reduction activities at the international, regional and national levels. DPM strategy enhances the way WMO and the National Meteorological and Hydrological Services, in partnership with other key organizations, can contribute to disaster reduction around the world. Through a phased implementation plan based on a multi-hazard framework, WMO - through a coordinated and systematic approach - addresses the needs and gaps in its core areas in different regions in the world.

'Regional Programme (RP)' cuts across and forms part of the WMO scientific and technical programmes. Main purpose is to give the required support to the regional associations. It comprises 2 main components - initial support to the Regional Programme and Regional Activities, which provide the necessary mechanism to ensure that the Programme's purposes are met, including assistance to the presidents of regional associations, support to sessions of regional associations and their working groups, assistance to members, particularly developing countries, for strengthening their National Meteorological and Hydrological Services to enable them to participate fully in and reap the maximum benefits from WMO Programmes. Assistance to members, which also aims at bridging the gap between National Meteorological and Hydrological Services, is given through regional events including regional technical conferences, training seminars, workshops as well as experts implementation coordination meetings.

WMO Resource Mobilization Office (RMO) ensures, through collaborative efforts of members, for their mutual benefit, the enhancement and development of the capabilities of the National Meteorological and Hydrological Services so they can contribute to, and participate efficiently in, the implementation of WMO Programmes, for the benefit of the global community and in support of national socio-economic development activities.
