World Meteorological Day

23 March

The UN system’s authoritative voice on the state and behavior of the Earth’s atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources.

The World Meteorological Organization is an intergovernmental organization with a membership of 187Member States and Territories. It originated from the International Meteorological Organization (IMO), which was founded in 1873. Established in 1950, WMO became the specialized agency of the United Nations for meteorology (weather and climate), operational hydrology and related geophysical sciences.

Since its establishment, WMO has played a unique and powerful role in contributing to the welfare of humanity. Under WMO leadership and within the framework of WMO programs, National Meteorological and Hydrological Services have contributed substantially to the protection of life and property against natural disasters, to safeguarding the environment and to enhancing the economic and social well-being of all sectors of society in areas such as food security, water resources and transport. It has a unique role within the UN system it facilitates the free and unrestricted exchange of data and information, products and services in real- or near-real time on matters relating to safety and security of society, economic well being and the prevention of the environment.

As weather and climate know no national boundaries, international cooperation at a global scale is essential for the development of meteorology and operational hydrology as well as to reap the benefits from their applications. WMO provides the framework for such international cooperation.

WMO is playing a leading role in international efforts to monitor and protect the environment through its Programs, such as the World Weather Watch Program, World Climate Program, the Atmospheric Research and Environment Program, and the Hydrology and Water Resources Program. For instance, in collaboration with the UN agencies and the NMHSs of Members, WMO continues to support the implementation of relevant conventions such as the UN Framework Convention on Climate Change, the International Convention to Combat Desertification, and the Vienna Convention on the Protection of Ozone Layer and its Protocols and Amendments. WMO is instrumental in providing advice and assessments to governments on matters relating to the above Conventions. These activities contribute towards ensuring the sustainable development and well-being of nations.

In the specific case of weather natural disasters which account for nearly three-quarters of all are such events, WMO’s programs provide the vital information for the advance warnings that save many lives and reduce damage to property and the environment. Human induced disasters chemistry, nuclear and forest fire. Numerous studies have shown that, apart from the incalculable benefit to human well-being, every dollar invested in meteorological and hydrological services produces an economic return many times greater, often ten times or more.

The vision of the WMO for the Sixth Long-term Plan (2004-2011) is to provide world leadership in expertise and international cooperation in weather, climate, hydrology and water resources, and related environmental issues, and thereby to contribute to the safety and well being of people throughout the world and to the economic benefit of all nations.
