THE WORLD METEOROLOGICAL ORGANIZATION (WMO) is a specialized agency of the United Nations WMO was created: to facilitate international co-operation in the establishment of networks of stations and centres to provide meteorological and hydrological services and observations, to promote the establishment and maintenance of systems for the rapid exchange of meteorological and related information, to promote standardization of meteorological and related observations and ensure the uniform publication of observations and statistics, to further the application of meteorology to aviation, shipping, water problems, agriculture and other human activities, to promote activities in operational hydrology and to further close co-operation between Meteoro­ logical and Hydrological Services, to encourage research and training in meteorology and, as appropriate, in related fields. The World Meteorological Congress is the supreme body of the Organization. It brings together the delegates of all Members once every four years to determine general policies for the fulfilment of the purposes of the Organization. The Executive Council is composed of 36 directors of national Meteorological or Hydrometeorological Services serving in an individual capacity; it meets at least once a year to supervise the programmes approved by Congress. Six Regional Associations are each composed of Members whose task is to co-ordinate meteorological and related activities within their respective regions. Eight Technical Commissions composed of experts designated by Members, are responsible for studying meteorological and hydrological operational systems, applications and research.
