The International Meteorological Convention was ratified by 30 countries
This established the World Meteorological Organization as an intergovernmental body
The goal was to coordinate weather observations and data sharing
March 23 became WMO's founding date and annual celebration
1951 — WMO Became UN Specialized Agency:
United Nations recognized WMO as official specialized agency
Organization gained authority to coordinate global weather services
International standards for meteorological observations were established
Global data exchange networks began connecting all weather services
1960 — First World Meteorological Day Celebrated:
WMO designated March 23 as annual World Meteorological Day
First celebration raised awareness about meteorology's importance
Annual themes began highlighting specific weather and climate issues
Member countries organized events promoting meteorological services
1963 — World Weather Watch Launched:
WMO established comprehensive global weather monitoring system
Satellites, weather stations, and ships created worldwide observation network
Real-time data sharing revolutionized weather forecasting accuracy
International cooperation became foundation of modern meteorology
Present — Climate Change Dominates WMO Focus:
Early warning systems protect billions from extreme weather disasters
