World Meteorological Day

Each year, on 23 March, the World Meteorological Organization, its 191 Members and the worldwide meteorological community celebrate World Meteorological Day around a chosen theme. This day commemorates the entry into force, on that date in 1950, of the WMO Convention creating the Organization. Subsequently, in 1951, WMO was designated a specialized agency of the United Nations System. (http://www.wmo.int/worldmetday/)
