Considered 'the Twister Bible' this was the first (and only) advanced book on tornadoes at the time; influencing an entire generation of meteorologists. This book contributed to the advancement of this field of study as its material was unavailable elsewhere. Between its first hand accounts of scientific observation of tornadoes alongside its unique photographs unavailable elsewhere, this title became University of Oklahoma Press' best seller of all time; at the time. A seminal classic in the study of tornadoes; in its original, uncommon DJ; first edition; first printing.
