'New' wave-like cloud finally wins official recognition “新”型波浪状云首次被列入官方图集

媒体英语 'New' wave-like cloud finally wins official recognition “新”型波浪状云首次被列入官方图集

Play audio file 文字稿 由世界气象组织（ World Meteorological Organization ）发布的《国际云图》首次正式列入了 12 种“新”型云。该图册可追溯到十九世纪，是一本用来观察及识别分布在全球各地的云型的参考书。《国际云图》最后更新于 1987 年，在平民科学家的呼吁下，新发布的电子版中收入了一种形似波浪的“粗云”。请听 Matt McGrath 的报道。

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.
