As a specialized agency of the United Nations, the World Meteorological Organization (WMO) is dedicated to international cooperation and coordination on the state and behavior of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources.

National Meteorological and Hydrological Services work around the clock to provide vital weather and climate information worldwide. Their early and reliable warnings of severe weather and fluctuations in air quality as well as of climate variability and change allow decision-makers, communities and individuals to be better prepared for weather and climate events. Their warnings help save life and property, protect resources and the environment and support socio-economic growth. WMO supports National Meteorological and Hydrological Services with this work and in meeting their international commitments in the areas of disaster risk reduction, climate change mitigation and adaptation, and sustainable development.
