Where it comes from
On 23 March 1950 the convention creating the World Meteorological Organization came into force, and the WMO marks that birthday every year. Its roots go back to 1873, when an International Meteorological Congress in Vienna set up a permanent committee so that countries could share weather observations across borders.
How it's celebrated
National weather services, many of them WMO members, open their doors, run school visits and explain how forecasts and early warnings are made, under a theme the WMO picks each year. It is a good day to thank the forecasters, look up at the clouds with a child, or learn what the symbols on a weather map mean.
Did you know
The 1873 Vienna congress brought together 32 delegates from 20 governments.
