The World Meteorological Day (WMD) is observed every year on 23rd March to mark establishment of World Meteorological Organization (WMO) on this day in 1950.
2017 Theme: “Understanding Clouds”. It seeks to highlight the enormous importance of clouds for weather climate and water. They play a critical role in the water cycle and shaping the global distribution of water resources. Clouds are central to weather observations and forecasts. Clouds are one of the key uncertainties in the study of climate change.
On this occasion, World Meteorological Organisation (WMO) launched new edition of the International Cloud Atlas. It is a treasure trove of hundreds of images of clouds, including a few newly classified cloud types and is single authoritative and most comprehensive reference for identifying clouds. It also features other meteorological phenomena such as rainbows, halos, snow devils and hailstones. This Atlas for the first time has been produced in a digital format and is accessible via both computers and mobile devices.
On this day in 1950 the World Meteorological Organisation (WMO) Convention came into force that aimed at creating WMO. Later in 1951, WMO became United Nations specialized agency for meteorology, geophysical sciences and operational hydrology.
