A World Meteorological Organization (WMO) committee of experts has established two new world records for the longest reported distance and the longest reported duration for a single lightning flash in, respectively, Brazil and Argentina.
Within its mandate in the areas of weather, climate and water, WMO focuses on many different aspects and issues from observations, information exchange and research to weather forecasts and early warnings, from capacity development and monitoring of greenhouse gases to application services and much, much more.

In 2015, the WMO Regional Meteorological Training Centres (RMTCs) that became the cornerstone of efforts to promote education and training, celebrate 50 years. How did they come to be and how have they evolved over the last decades? Most importantly, in the current environment of privatized meteorological service providers, do they remain pertinent?

Seven new generation geostationary satellites will be launched into positions over the equator within the next five years. These launches will drastically change the Space Component of the WMO Integrated Global Observing System (WIGOS) and National Meteorological and Hydrological Services are challenged to prepare for the advanced capabilities the satellites will offer. The imager capabilities, sampling rate, spectral resolution and spectral channels, of this new generation of satellites will drastically increase data rates – by an order of up to 100. All National Meteorological Hydrological...

Weather and climate know no national borders. The transformation of the International Meteorological Organization into the World Meteorological Organization (WMO) in 1950 was an essential response to the need to strengthen global cooperation in this scientific area. In 1960, the Executive Council of WMO established World Meteorological Day to build public awareness of the services provided by National Meteorological Services and WMO. These services involve the observation, collection, processing and dissemination of meteorological, hydrological and other related data and products. The 23rd of...

The World Weather Watch (WWW) is one of the crowning achievements of WMO. The celerity with which WMO responded to the introduction of meteorological satellites with the establishment of the WWW, and its subsequent adoption by all WMO Members, set a standard for international cooperation in operational programmes that remains unequalled today.

For 50 years, since Dave Keeling started monitoring carbon dioxide at Mauna Loa, Hawaii, and the South Pole, scientists have been tracking greenhouse and other trace gases in the global atmosphere. The results have revolutionized our understanding of biogeochemistry and demonstrated that human activities affect climate change and air quality.
