The establishment of the World Meteorological Organization in March 1950, following the entry into force of its Convention, and the designation of WMO in 1951 as a specialized agency of the United Nations, heralded a new era for international cooperation in the field of meteorology, hydrology and related geophysical sciences.
WMO works to facilitate worldwide cooperation within the design and delivery of meteorological services, foster the rapid exchange of meteorological information, advance the standardization of meteorological data, build collaboration between meteorological and hydrological services, encourage research and training in meteorology, and expand the employment of meteorology to profit other sectors like aviation, shipping, agriculture and water management.
