You?ll find a selection of some of the most startling and unusual cloud formations, from uniform streaks of ?cloud streets? to the odd bulbous ?lenticularis? that are commonly mistaken for UFOs. Each amazing photograph will be accompanied by Hamblyn?s entertaining and informative explanation of how the cloud was formed and the conditions in which a similar one might occur. The images chosen use satellite photography as well as ground-based pictures and the collection demonstrates the most unexpected and seemingly impossible patterns that can be created by the natural cycles of weather.
