In reality, however, the WMO is much older. It was originally founded as the International Meteorological Organization back in 1873. But in 1950, it changed its name, and in 1951, it came under the UN umbrella.

In the beginning, the work of the IMO (later WMO) was to set up meteorological stations and form them into organized networks. The information gained was then forwarded via telegraph lines to improve travel and shipping safety. Today, the WMO does much more than just that, but it continues to work to make weather forecasting accurate in order to benefit the public safety.

On World Meteorological Day, there are numerous special meetings and exhibits on weather and climate related themes held all over the world. There are also many special awards and prizes given out on this day for research and other achievements in the realm of meteorology.

Also, in some nations around the world, special stamps are issued every 23 March based on that year’s World Meteorological Day theme.
