This updated and revised volume in the Dangerous Weather series explores many aspects of weather as well as the science of weather. Organized and written in an easy-to-follow style, author Michael Allaby answers the most important questions students and non-specialists have about weather and he provides a general overview of the current information that shapes the way weather is understood and studied. Features include discussion of how the climates of the world have changed over the centuries; a 5,000-year chronology of dangerous weather, from c. 3,200 BCE to the present; a chronology of discoveries listing important developments in the understanding of weather, biographies of noted weather scientists, and advances in forecasting from c. 340 BCE to the present; easy-to-perform experiments (which require no special equipment) that explore various aspects of weather and weather science; weather classification and measurement scales, including the Beaufort Scale of Wind Strength, Saffir/Simpson Hurricane Scale, and the Fujita Tornado Intensity Scale; and a glossary of terms and concepts used throughout the book and series.
