The Book of Clouds

See the sky as you never have before. Using a series of his awe-inspiring images, photographer and scientist John Day—who has a Ph.D. in cloud physics and is known round the world as "The Cloudman"—introduces us to earth's great skyscape. His spectacular portfolio of pictures captures a variety of cloud forms and shapes, ranging from cottony-soft cumulus clouds to frightening, whirling funnels, as well as a number of optical effects, such as coronas and halos, seen in the heavens above. A magnificent cloud chart; an explanation of clouds formation; hints on forecasting, observing, and photographing clouds; and his "Ten Reasons to Look Up" teach us to use our inner eye to really perceive those familiar fleeting forms.
