Tornadoes are the most violent, magnificent, and utterly unpredictable storms on earth, reaching estimated wind speeds of 300 mph and leaving swathes of destruction in their wake. In Tornado Alley, Howard Bluestein draws on two decades of experience chasing and photographing tornadoes across the American Plains to present a historical account of the study of tornadoes and the great thunderstorms that spawn them. A century ago, tornado warnings were so unreliable that they usually went unreported. Today, despite cutting-edge Doppler radar technology and computer simulation, these storms remain remarkably difficult to study. Leading scientists still conduct much of their research from the inside of a speeding truck, and often contend with jammed cameras, flash floods, and windshields smashed by hailstones and flying debris. Using over a hundred diagrams, models, and his own spectacular color photographs, Bluestein documents the exhilaration of hair-raising encounters with as many as nine tornadoes in one day, as well as the crushing disappointment of failed expeditions and ruined equipment. Most of all, he recreates the sense of beauty, mystery, and power felt by the scientists who risk their lives to study violent storms. For scientists, amateur weather enthusiasts, or anyone who's ever been intrigued or terrified by a darkening sky, Tornado Alley provides not only a history of tornado research but a vivid look into the origin and effects of nature's most dramatic phenomena.
