大自然的魔法 天空中的奇观 关于云之飘逸变幻，唐朝诗皎然有诗曰：舒卷意何穷，萦流复带空。有形不累物，无迹去随风。莫怪长相逐，飘然与我同 漂浮在空中的标本 从左至右分别是，东南亚的层积云；冰岛低垂的层云；澳洲昆士兰北部天空中被称之为晨曦的卷云；内华达与加州边界上空的高积荚状云。 By CORNELIA DEAN 浮云是大气制造的“魔法”，它们转瞬即逝而且不断变化。当然，它们无法被收集并存储。不过，我们根本无需什么特定装置去收集浮云：你只要注视它，然后记录下来就可以了。Hence “The Cloud Collector’s Handbook,” published by Chronicle Books, a serious yet charming field guide to clouds. The book teaches readers how to identify clouds they have seen and gives them a place to record the sightings, just the way birders create life lists of the birds they have spotted. It even has a scoring system, in which cloudspotters receive 10 points for ordinary clouds like nimbostratus, the more or less featureless rain clouds people typically have in mind when they say clouds are depressing; 40 points for a cumulonimbus storm cloud, the anvil-shaped “king of clouds”; and more points for more exotic formations. Mr. Pretor-Pinney resists the idea that cloudspotting is merely funny, or even merely fun. Instead, he said, it’s a way of training yourself to be aware of the natural world, “of being receptive when something is happening in the sky and noticing it.” Clouds are an important and necessary part of our environment, he notes, and anyway an endless succession of cloudless days would be boring. So Mr. Pretor-Pinney has little patience for people who dream of sunnier climes when clouds fill the sky. 云彩是自然环境重要且必要的组成部分，没完没了的晴朗少云天气总会让人感到厌倦。 在日常环境中发现美好，对周遭的一切产生兴奋之情或变得兴趣盎然，并在其中找到自我，这才是幸福感的真正源头。 Up in the Clouds 相关图集：云卷云舒 Stratocumulus.

These low-lying clouds “can give you a strangely claustrophobic feeling.” When a stratus cloud forms at a very low level, it is ca
