The bulk of the book is a superb collection of just about every type of weather phenomenon you can think of - particularly different types of cloud. Each colour plate has an informative description, telling you how the phenomenon originates and what it means (e.g. forecasting using the cloud types). Before the photographs is a short collection of essays on the weather that virtually provides a stand-alone introduction to the weather, what causes it, and extreme weather events. Overall exceptionally useful for anyone interested in the weather.
