Effects of Atmospheric Rivers

Abstract

This book is intended to summarize the state of the science of atmospheric rivers (ARs) and itsapplication to practical decision-making and broader policy topics. It is the first book on thesubject and is intended to be a learning resource for professionals, students, and indeed anyonenew to the field, as well as a reference source for all.We first envisioned the book during the heady days of 2013 when the Center for WesternWeather and Water Extremes was being planned and established. However, right from the start,we recognized that the effort required would exceed that of any single or couple of authors, andthat the book would surely benefit from a broad range of perspectives and knowledge from avariety of leaders of atmospheric-river science from around the world. Consequently, the firststep toward this book was to organize workshops addressing various aspects of AR science thatwe were able to co-opt, in part, for recruitment of, and discussions among, possible contributingauthors. This led to the diverse authorship team that ultimately wrote this book, as well asour engagement of an experienced publication and book editing team. Among the strategiesagreed to by the contributing authors, one key decision was that the book would focus mostlyon results that have already been published and would emphasize figures and references fromthose formal publications. Where vital, new information has been developed and incorporated.Each chapter was led by a few expert lead authors recruited by the four of us, and those chapterleads recruited contributions from other experts on the chapter topic. Each chapter wasreviewed by other specialists who were not part of its authorship team, generally including onehighly technical expert and one reviewer intended to represent members of a broader audience.This helped ensure the accuracy of interpretations as well as high standards and accessibilityof presentation. We, the editors of the book, reviewed all chapters at various stages of compositionand layout.Given currently high levels of interest in ARs in the scientific community as well as by thepublic, we hope that the book will be a useful starting place for many readers. Writing a bookabout a topic that is as new and that is advancing as quickly as AR science is today (in 2018)poses many difficult challenges but, with the help of the large team of expert authors who havecontributed, we believe that, with this book, we are providing a firm foundation for futureexpansion and advances in this important field.
