National Meteorological and Hydrological Services work around the clock to monitor Earth System 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.
WMO facilitates and promotes:
- the establishment of an integrated Earth System observation network to provide weather, climate and water-related data
- the establishment and maintenance of data management centres and telecommunication systems for the provision and rapid exchange of weather, climate and water-related data
- the creation of standards for observation and monitoring in order to ensure adequate uniformity in the practices and procedures employed worldwide and, thereby, ascertain the homogeneity of data and statistics
- the provision of weather, climate and water-related services - through the application of science and technology in operational meteorology and hydrology - to reduce disaster risks and contribute to climate change adaptation, as well as for sectors such as transport (aviation, maritime and land-based), water resource management, agriculture, health, energy and other areas
- activities in operational hydrology as well as closer cooperation between National Meteorological and Hydrological Services in states and territories where they are separate
- the coordination of research and training in meteorology and related fields.
