Weather, climate or water-related phenomena cause hazards such as drought, floods, windstorms, tropical cyclones, extreme hot and cold temperatures, landslides and wildfires; and are also linked to diseases like malaria and infestations of insects such as locusts.

Weather and climate ignores political borders. When you cross from one country to another, it does not stop raining just because you have crossed the border.

All nations, therefore, have to cooperate to develop their meteorological skills and to predict the weather.  Information needs to be exchanged quickly and freely around the globe.

This is why WMO was created.

The World Meteorological Organization (WMO) provides world leadership, expertise and international cooperation in:

• Weather
• Climate
• Hydrology and water resources
• Related environmental issues

WMO coordinates the activities of countries around the world in producing, exchanging and using information about weather, climate and water. Together, these factors account for 90% of all disasters.
