Many climatic extremes around the globe, such as severe droughts and floods, can be attributed to the periodic warming of the equatorial Pacific sea surface, termed the El Niño or Southern Oscillation (ENSO). Advances in our understanding of ENSO, in which Edward Sarachik and Mark Cane have been key participants, have led to marked improvements in our ability to predict its development months or seasons, allowing adaptation to global impacts. The book introduces basic concepts and builds to more detailed theoretical treatments. Chapters on the structure and dynamics of the tropical ocean and atmosphere place ENSO in a broader observational and theoretical context. Chapters on ENSO prediction, past and future, and impacts introduce broader implications of the phenomenon. This book provides an introduction to all aspects of this most important mode of global climate variability, for research workers and students of all levels in climate science, oceanography and related fields.

El Niño is a meteorologic/oceanographic phenomenon that occurs sporadically (every few years) at low latitudes. It is felt particularly strongly in the eastern Pacific region, notably from the equator southwards along the coasts of Ecuador and Peru. The El Niño is a component of the ENSO (El Niño Southern Oscillation) which accentuates the intimate and causal connection between atmospheric and marine processes. Obvious manifestations of El Niño in the eastern Pacific are anomalous warming of the sea; reduced upwelling; a marked decline in fisheries, and high rainfall with frequent flooding.

"Cesar Caviedes provides the first comprehensive historical account of El Nino, the fascinating and disruptive weather phenomenon that has affected weather cycles all over the globe for thousands of years. Combining scientific accuracy with readable presentation, he brings together all existing information, references, and clues about past El Nino occurrences and their impact on political, military, social, economic, and environmental history. This sweeping demonstration of the impact of climatic fluctuation on human history will be fascinating to the scientific community as well as to the general public."--Jacket.

This book covers the time span from the first indications of El Niño (May 1997) until its reversal (June 1998). The focus is largely on the United States, where El Niño produced widespread changes in how the public perceives weather and in the accuracy of forecasts. Among the key issues it examines are how the news media interpreted and dramatized El Niño and the reaction both of the public and decision-makers (the latter based on interviews with agribusiness, utilities, water management agencies, etc.); the scientific issues emerging from the event; and the social and economic consequences of the event. Finally, it suggests what can and should be done when El Niño occurs in the future.

This book offers a new perspective on those El Niños that grow to extraordinary magnitudes, putting forward the claim that these “super El Niños” should be grouped into an isolated cluster. All known super El Niños exhibit pronounced features that are seldom seen in regular El Niños. Super El Niño events, which are marked by a highly deterministic life cycle, will dominate the Earth’s climate for several years. This study identifies the pre-conditions and a booster mechanism that lead to the runaway growth of super El Niños, which is featured by the intense interaction between the anomalous circulation in middle/high latitudes and the ENSO source area. The study not only sheds new light on the fundamental mechanism of the ENSO but also contributes to improving its extended predictability.

El Nino and the Southern Oscillation is by far the most striking phenomenon caused by the interplay of ocean and atmosphere. It can be explained neither in strictly oceanographic nor strictly meteorological terms. This volume provides a brief history of the subject, summarizes the oceanographic and meteorological observations and theories, and discusses the recent advances in computer modeling studies of the phenomenon.Key Features* Includes a comprehensive and up-to-date research survey* Discusses in detail sophisticated computer models* Provides a clear exposition

This textbook provides a mathematical introduction to the theory of large-scale ocean circulation and is accessible for readers with an elementary knowledge of mathematics and physics, including continuum mechanics and solution methods for ordinary differential equations. The book consists of four parts. Part I (chapters 1 - 4) is a very brief introduction to ocean circulation and the mathematical formulation of the governing equations of ocean flows. In addition, concepts are introduced that are necessary to describe and understand large-scale ocean currents. In part II (chapters 5 - 10), the theory of mid-latitude wind-driven ocean circulation is presented. The consideration of model development includes a top-down approach and reduced equations are derived using asymptotics and scaling. Part III (chapters 11 - 12) focuses on the understanding of equatorial currents and El Nino. In the last part IV, chapters 13 - 16, the theory of planetary scale flows is presented, covering topics such as the thermocline problem, the Antarctic Circumpolar Current, the stability of the thermohaline circulation and the Arctic Ocean circulation. At the end of each chapter several exercises are formulated. Many of these are aimed to further develop methodological skills and to get familiar with the physical concepts. A few exercises also serve to introduce extension topics. Fully worked out answers to all exercises can be downloaded from the book web site.

Every year, extreme climatic problems occur around the globe, with droughts in some places and floods in others. Recently, we have come to recognise that some of these widely dispersed climatic extremes might have a common origin in the periodic warming of sea surface water in the central and eastern equatorial Pacific Ocean. A century ago, Peruvian fishermen connected this appearance of warm water every December to changes in fish numbers and christened it 'El Niño, the Spanish term for the Christ Child. In some years, El Niño lingers, and seems to be connected with droughts in Australia, Brazil or India, reduced incidence of tropical hurricanes on the east coast of the US, and floods in Peru. Currents of Change explains in simple terms what El Niño, is, how its effects might be forecast and its far reaching impacts on all of us.
