由世界氣象組織（ World Meteorological Organization ）發(fā)布的《國際云圖》首次正式列入了 12 種“新”型云。該圖冊可追溯到十九世紀(jì)，是一本用來觀察及識別分布在全球各地的云型的參考書?！秶H云圖》最后更新于 1987 年，在平民科學(xué)家的呼吁下，新發(fā)布的電子版中收入了一種形似波浪的“粗云”。請聽 Matt McGrath 的報(bào)道。

Looking like the roiling sea seen from beneath the waves, asperitas clouds were first photographed back in 2006 by amateur observers. Since then, a global campaign to recognise the cloud type has gathered pace, resulting in a formal classification in this first digital edition of the atlas.

Other odd-shaped clouds and weather phenomena have now been added to this global reference book that dates back to 1896. Contrails from the wispy vapours of aeroplanes have officially been recognised, as have rainbows, halos, snow devils and hailstones.

One key development that has helped revolutionise the atlas has been the smartphone. Experts say the public’s ability to capture the often fleeting formations will lead to the discovery of many new clouds in the years ahead.
