World Meteorological Organization (WMO)

WMO is the United Nations’ specialized agency for weather, climate, and water. Working across the entire cycle of inland water management, WMO supports countries to transform data into action – from monitoring rivers and rainfall patterns to predicting water-related hazards, from enhancing early warning systems to guiding smarter water use for people and nature. By providing reliable data and science-based guidance, WMO helps countries make informed decisions for sustainable water use and climate resilience, protecting people, ecosystems, and economies. Through WHCA, WMO partners with regional and national meteorological and hydrological agencies and with local communities, developing operational tools and providing technical guidance to improve hydrological observations, impact-based forecasting, and early warning systems.
