Background

 

Each year, on 23 March, the World Meteorological Organisation, its 191 Members and the worldwide meteorological community celebrate World Meteorological Day around a chosen theme.

This day commemorates the entry into force, on that date in 1950, of the World Meteorological Organisation (WMO) Convention creating the Organisation. Subsequently, in 1951, WMO was designated a specialised agency of the United Nations System.

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

Theme

 

Understanding clouds is the theme of World Meteorological Day 2017 to highlight the enormous importance of clouds for weather, climate and water. Clouds are central to weather observations and forecasts. Clouds are one of the key uncertainties in the study of climate change: we need to better understand how clouds affect the climate and how a changing climate will affect clouds. They play a critical role in the water cycle and in shaping the global distribution of water resources.
