A new edition of the International Cloud Atlas is scheduled to be released simultaneously with this Bulletin following three years of hard work.
The WMO Bulletin is the official journal of the World Meteorological Organization. The Bulletin was first published in 1952 and is produced in English, French, Russian and Spanish. The Bulletin is currently issued twice yearly in print and online.
Humanity has a primordial fascination with clouds. The meteorological and hydrological communities have come to better understand cloud processes through decades of observation and research.
