The date when the World Meteorological Organization (WMO) was established, which is 23 March 1950, was dubbed World Meteorological Day. Every year, the organisation announces a slogan for this day. All member countries celebrate World Meteorology Day. The day is celebrated every year to honour the entry into force of the convention that formed World Meteorological Organization.
Also, the day highlights the contribution that Hydrological Services and National Meteorological make to society’s safety and well-being. The UN’s (United Nations) World Meteorological Day is held annually around or on 23 March to remember the establishment of WMO in 1950, on that date. Many events and activities are organised for this occasion.
World Meteorological Day usually features events like exhibitions and symposia for meteorological professionals, conferences, the public and community leaders. Some events aim to get the media attention and raise the meteorology’s profile. Also, many prizes for meteorological study are announced or presented close or on World Meteorological Day.
Many countries issue special postage stamp cancellation mark or postage stamps to celebrate this day. The stamps usually reflect the theme of the event or mark a nation’s meteorology achievements.
World Meteorological Day theme, 23 March 2018 will be Weather-ready, climate-smart. A new theme is always allocated to each and every different year for the World Meteorological Day. In 2007, WMO held a photo competition on the theme of that year entitled “Hotter, drier, wetter. Face the Future.” Also, the World Meteorological Day marked the launching of a new International Cloud Atlas edition.
