Book Description
El Nino events affect the wave climate in the eastern north Pacific which can have a significant impact on the behavior of west coast beaches. In California, El Nino winters are characterized by anomalously higher and more southerly winter wave energy. This study seeks to quantify beach changes during the 2009/2010 El Nino Modoki from Point Conception to the Los Angeles-Long Beach Harbor, a 265-km portion of the Southern California Bight. Two LiDAR datasets from September of 2009 and September of 2010 were used to measure the change in position of the mean high water (MHW) and mean sea level (MSL) shorelines at over 5,000 transects spaced 50 m apart, as well as determine beach volume changes. Over the entire study area, during this one-year period, the MHW shoreline accreted by an average of 0.51 m while the mean beach elevation dropped by 0.05 m, but local beach response within the region was highly variable. Distinct cells of erosion and accretion throughout the region suggest that the observed beach changes are a result of a combination of factors including geography, shoreline orientation, beach morphology, artificial structures, sediment supply, and alongshore variations in wave energy and direction. Predictions of the increasing frequency and/or intensity of El Nino events under global warming conditions underscore the importance of understanding how coastlines will respond to changes in wave climate and may help in future coastal management.

Book Description
Although we are seeing more weather and climate extremes, individual extreme events are very diverse and generalization of trends is difficult. For example, mid-latitude and subtropical climate extremes such as heat waves, hurricanes and droughts have increased, and could have been caused by processes including arctic amplification, jet stream meandering, and tropical expansion. This volume documents various climate extreme events and associated changes that have been analyzed through diagnostics, modeling, and statistical approaches. The identification of patterns and mechanisms can aid the prediction of future extreme events. Volume highlights include: Compilation of processes and mechanisms unique to individual weather and climate extreme events Discussion of climate model performance in terms of simulating high-impact weather and climate extremes Summary of various existing theories, including controversial ones, on how climate extremes will continue to become stronger and more frequent Climate Extremes: Patterns and Mechanisms is a valuable resource for scientists and graduate students in the fields of geophysics, climate physics, natural hazards, and environmental science.

Book Description
Comprehensive and up-to-date information on Earth’s most dominant year-to-year climate variation The El Niño Southern Oscillation (ENSO) in the Pacific Ocean has major worldwide social and economic consequences through its global scale effects on atmospheric and oceanic circulation, marine and terrestrial ecosystems, and other natural systems. Ongoing climate change is projected to significantly alter ENSO's dynamics and impacts. El Niño Southern Oscillation in a Changing Climate presents the latest theories, models, and observations, and explores the challenges of forecasting ENSO as the climate continues to change. Volume highlights include: Historical background on ENSO and its societal consequences Review of key El Niño (ENSO warm phase) and La Niña (ENSO cold phase) characteristics Mathematical description of the underlying physical processes that generate ENSO variations Conceptual framework for understanding ENSO changes on decadal and longer time scales, including the response to greenhouse gas forcing ENSO impacts on extreme ocean, weather, and climate events, including tropical cyclones, and how ENSO affects fisheries and the global carbon cycle Advances in modeling, paleo-reconstructions, and operational climate forecasting Future projections of ENSO and its impacts Factors influencing ENSO events, such as inter-basin climate interactions and volcanic eruptions The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the editors.

Book Description
Measurement, analysis and modeling of extreme precipitation events linked to floods is vital in understanding changing climate impacts and variability. This book provides methods for assessment of the trends in these events and their impacts. It also provides a basis to develop procedures and guidelines for climate-adaptive hydrologic engineering. Academic researchers in the fields of hydrology, climate change, meteorology, environmental policy and risk assessment, and professionals and policy-makers working in hazard mitigation, water resources engineering and climate adaptation will find this an invaluable resource. This volume is the first in a collection of four books on flood disaster management theory and practice within the context of anthropogenic climate change. The others are: Floods in a Changing Climate: Hydrological Modeling by P. P. Mujumdar and D. Nagesh Kumar, Floods in a Changing Climate: Inundation Modeling by Giuliano Di Baldassarre and Floods in a Changing Climate: Risk Management by Slodoban Simonović.

Book Description
Crowded into the beautiful, narrow strip at the edge of the ocean, the large number of people who live near California's dynamic coastline often have little awareness of the hazards—waves, tides, wind, storms, rain, and runoff—that erode and impact the coast and claim property on a regular basis. This up-to-date, authoritative, and easy-to-use book, a geological profile of the California coast from Mexico to the Oregon border, describes the landforms and processes that shape the coastline and beaches, documents how erosion has affected development, and discusses the options that are available for dealing with coastal hazards and geologic instability. A completely revised and updated edition of Living with the California Coast (1985), this book features hundreds of new photographs and the latest data on human activity on the coast, on climate change, on rising seas levels, and on coastal erosion and protection. With its dramatic photographs and mile-by-mile maps, Living with the Changing California Coast will be an essential resource for those intending to buy or build along the coast, those who need specific information about various coastal regions, and those who are seeking information about how this remarkable coastline has evolved. *279 photographs portray natural coastal features and processes and illustrate many instances of what can happen to buildings on the coast *81 maps, covering the entire coast, detail types of coastal landforms, coastline erosion rates, locations of seawalls or armor, and other specific areas of interest *Offers specific advice for homebuyers,residents, and developers on which areas to avoid, on what safety measures should be taken, and on what danger signals should be heeded

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 147. It is more than 30 years since the publication of Jacob Bjerknes' groundbreaking ideas made clear the importance of ocean-atmosphere interaction in the tropics. It is now more than 20 years since the arrival of a massive El Niño in the fall of 1982 set off a cascade of observational and theoretical studies. During the following decades, the climate research community has made exceptional progress in refining our capacity to observe earth's climate and theorize about it, including new satellite-based and in situ monitoring systems and coupled ocean-atmosphere predictive numerical models. Of equal importance. is the expanding scope ofresearch, which now reaches far beyond the Pacific El Niño and includes climate phenomena in other ocean basins. In order to cover the now global context of ocean-atmosphere interaction we have organized this monograph around five principal themes, each introduced by one or more broad overview papers. Theme I covers interaction and climate variability in the Pacific sector, with extensive discussion of El Niño-Southern Oscillation, and with the possible causes and consequences of variability on both shorter and longer timescales. Theme II is devoted to interaction in the Atlantic sector. This basin exhibits complex behavior, reflecting its geographic location between two major zones of convection as well as neighboring the tropical Pacific. Theme III reviews the recent, exciting progress in our understanding of climate variability in the Indian sector. Theme IV addresses the interaction between the tropics and the extratropics, which are linked through the presence of shallow meridional overturning cells in the ocean. Finally, Theme V discusses overarching issues of cross-basin interaction.
