The mission of WMO is to:
- Facilitate worldwide cooperation in the establishment of networks of stations for the making of meteorological observations as well as hydrological and other geophysical observations related to meteorology, and to promote the establishment and maintenance of centres charged with the provision of meteorological and related services.
- Promote the establishment and maintenance of systems for the rapid exchange of meteorological and related information.
- Promote standardization of meteorological and related observations and to ensure the uniform publication of observations and statistics.
- Further the application of meteorology to aviation, shipping, water problems, agriculture and other human activities.
- Promote activities in operational hydrology and to further close cooperation between Meteorological and Hydrological Services.
- Encourage research and training in meteorology and, as appropriate, in related fields, and to assist in coordinating the international aspects of such research and training.
WMO has seven strategic priorities
Disaster Risk Reduction
Improve the accuracy and effectiveness of impact-based forecasts and multi-hazard early warnings of high impact meteorological, hydrological and related environmental hazards from the tropics to the poles, thereby contributing to international efforts on disaster risk reduction, resilience and prevention, in particular in response to the risks associated with increasing population exposure.
Global Framework for Climate Services
Implement climate services, particularly for countries that lack them by:
(a) establishing regional climate centres;
(b) identifying user requirements for climate products;
(c) developing the Climate Services Information System (CSIS); and
(d) advancing the Sub-seasonal to Seasonal (S2S) Prediction skill.
WMO Integrated Global Observing System (WIGOS)
Strengthen the global observing systems through full implementation of WIGOS and WMO Information System (WIS) for robust, standardized, integrated, accurate and quality assured relevant observations of the Earth System to support all WMO priorities and expected results.
Improve the ability of National Meteorological and Hydrological Services to provide sustainable high quality services in support of safety, efficiency and regularity of the air traffic management worldwide, with due account to environmental factors by:
(a) accelerating the implementation of International Civil Aviation Organization (ICAO) / WMO competency and qualification standards and Quality Management Systems;
(b) addressing emerging requirements and challenges related to the 2013-2028 Global Air Navigation Plan, in particular concerning ICAO’s Block 1 Upgrades (ASBUs); and
(c) strengthening the sustainability and competitiveness of aeronautical meteorological service provision through improved cost recovery mechanisms and suitable business models for service delivery frameworks.
Polar and High Mountain Regions
Improve operational meteorological and hydrological monitoring, prediction and services in polar, high mountain regions and beyond by:
(a) operationalizing the Global Cryosphere Watch (GCW);
(b) better understanding the implications of changes in these regions on the global weather and climate patters; and
(c) advancing the polar prediction under the Global Integrated Polar Prediction System (GIPPS).
Enhance the capacity of National Meteorological and Hydrological Services to deliver on their mission by developing and improving competent human resource, technical and institutional capacities and infrastructure, particularly in developing, least developed and small island developing states.
Improve efficiency and effectiveness of WMO though adopting continuous improvement measures and recommendations based on a strategic review of WMO structures, operating arrangements and budgeting practices.
