World Meteorological Day is celebrated on 23rd March every year to attract attention towards weather and climate for the safety and well-being of the society.
This day showcases the essential contribution of National Meteorological and Hydrological Services to the safety and wellbeing of society and is celebrated with activities around the world. The themes chosen for World Meteorological Day reflect topical weather, climate, or water-related issues.
World Meteorological Day: Theme and Significance
WMO Executive Council has selected the following themes for the upcoming celebrations of World Meteorological Day for 2021: “The Ocean, our climate and weather” in conjunction with the launch of the United Nations Decade of Ocean Science for Sustainable.
The World Meteorological Day theme – The ocean, our climate, and weather – celebrates WMO’s focus in connecting the ocean, climate, and weather within the Earth System. It also marks the starting year of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030). The Decade galvanizes efforts to gather ocean science – through innovative and transformative ideas – as the basis of information to support sustainable development. WMO, as the United Nations specialized agency for climate, weather, and water, strives to support understanding the inextricable link between ocean, climate, and weather.
World Meteorological Day: History
The WMO originated from the International Meteorological Organization, a nongovernmental organization founded in 1873 as a forum for exchanging weather data and research. Proposals to reform the status and structure of the IMO culminated in the World Meteorological Convention of 1947, which formally established the World Meteorological Organization. The Convention entered into force on 23 March 1950, and the following year the WMO began operations as an intergovernmental organization within the UN system.
So, that’s why every year on 23 March, the World Meteorological Organization commemorates the coming into force of the Convention establishing the World Meteorological Organization on 23 March 1950.
Covering some 70% of the Earth’s surface, the ocean is a major driver of the world’s weather and climate. It also plays a central role in climate change. The ocean is also a major driver of the global economy, carrying more than 90% of world trade and sustaining the 40% of humanity that lives within 100 km of the coast. Recognizing this, National Meteorological and Hydrological Services and researchers regularly monitor the ocean and how it is changing, modeling how it affects the atmosphere and delivering a wide variety of marine services, including supporting coastal management and Safety of Life at Sea.
