Book excerpt: This book surveys the past, present, and potential future variability of hurricanes and typhoons on a variety of timescales using newly developed approaches based on geological and archival records, in addition to more traditional approaches based on the analysis of the historical record of tropical cyclone tracks. A unique aspect of the book is that it provides an overview of the developing field of paleotempestology, which uses geological, biological, and documentary evidence to reconstruct prehistoric changes in hurricane landfall. The book also presents a particularly wide sampling of ongoing efforts to extend the best track data sets using historical material from many sources, including Chinese archives, British naval logbooks, Spanish colonial records, and early diaries from South Carolina. The book will be of particular interest to tropical meteorologists, geologists, and climatologists as well as to the catastrophe reinsurance industry, graduate students in meteorology, and public employees active in planning and emergency management.
