Today is the World Meteorological Day or the International Day of Meteorology.
Wikipedia and the WMO itself state that this day was invented to remember the introduction of the World Meteorology Organization on the 23rd of March 1950, short WMO. Through worldwide weather recording the WMO enabled reliable weather forecasts. Interestingly this organization cooperated on an international basis regardless of any political circumstances.
Every year the World Meteorological Day follows a special theme. The topic this year is “Watching the weather to protect life and property” – because its exactly 50 years of World Weather Watch today.
