This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical and extratropical Pacific decadal climate variability substantially impact physical and biological systems in the Pacific Ocean and strongly influence global climate through teleconnection patterns. Current understanding of Pacific decadal climate variability centers around the El Niño-Southern Oscillation (ENSO), the Aleutian Low (AL), and the Pacific Decadal Oscillation (PDO). However, recent literature has highlighted the emerging roles of secondary modes of variability of the tropical and extratropical Pacific atmosphere and ocean in global climate change: the Central Pacific Warming (CPW) phenomenon, the North Pacific Oscillation (NPO), and the North Pacific Gyre Oscillation (NPGO). This work analyzes the statistics and uncertainties behind Pacific interannual and decadal-scale climate variability, and focuses on better understanding the roles of the CPW, NPO, and NPGO in the climate system.

Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty for Everyone The one thing that is certain about the world is that the world is uncertain. I have here, the question that apart of the matter, living matter, has to resolve in each and every one of its moments of existance. The environment of a living being is apart of the living being where it turns out, the rest of the living beings live. This is the drama of life on earth. Every living individual debates with his environment, exchanging matter, energy and information in the hope of staying alive, the same as all living beings who share that same environment. The adven ture of a living being (of all living beings ) is to maintain reasonable independ ence in face ofthe fluctuations ofuncertainty within the environment. The range of restrictions and mutual relationships is colossal. How is the tran seendental pretension of staying alive regulated? There is an equation imposed by the laws ofthermodynamics and the mathematical theory ofinformation about the interaction ofa living being with his environment which we could state like this: The complexity 01 a living individual plus his capacity for anticipation in re spect to his environment is identical to the uncertainty of the environmentplus the capacity of that living being to change the environment.

Available in PDF, EPUB and Kindle. Book excerpt: How can we understand and rise to the environmental challenges of global change? One clear answer is to understand the science of global change, not solely in terms of the processes that control changes in climate and the composition of the atmosphere, but in how ecosystems and human society interact with these changes. In the last two decades of the twentieth century, a number of such research effortsâ€"supported by computer and satellite technologyâ€"have been launched. Yet many opportunities for integration remain unexploited, and many fundamental questions remain about the earth's capacity to support a growing human population. This volume encourages a renewed commitment to understanding global change and sets a direction for research in the decade ahead. Through case studies the book explores what can be learned from the lessons of the past 20 years and what are the outstanding scientific questions. Highlights include: Research imperatives and strategies for investigators in the areas of atmospheric chemistry, climate, ecosystem studies, and human dimensions of global change. The context of climate change, including lessons to be gleaned from paleoclimatology. Human responses toâ€"and forcing ofâ€"projected global change. This book offers a comprehensive overview of global change research to date and provides a framework for answering urgent questions.
Download or read book Decade to Century Scale Climate Variability and Change written by National Research Council and published by National Academies Press. This book was released on 1998-12-24 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society today may be more vulnerable to global-scale, long-term, climate change than ever before. Even without any human influence, past records show that climate can be expected to continue to undergo considerable change over decades to centuries. Measures for adaption and mitigation will call for policy decisions based on a sound scientific foundation. Better understanding and prediction of climate variations can be achieved most efficiently through a nationally recognized "dec-cen" science plan. This book articulates the scientific issues that must be addressed to advance us efficiently toward that understanding and outlines the data collection and modeling needed.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on two major challenges in the climate sciences: 1) to describe the decadal-to-centennial variations in instrumental and proxy records; and 2) to distinguish between anthropogenic variations and natural variability. The National Taiwan University invited some of the world's leading experts across the areas of observational analysis, mathematical theory, and modeling to discuss these two issues. The outcome of the meeting is the 23 chapters in this book that review the state of the art in theoretical, observational and modeling research on internal, unforced and externally forced climate variability. The main conclusion of this research is that internal climate variability on decadal and longer time scales is so large that sidestepping it may lead to false estimates of the climate's sensitivity to anthropogenic forcing.World Scientific Series on Asia-Pacific Weather and Climate is indexed in SCOPUS.

Download or read book Ocean Circulation written by Andreas Schmittner and published by John Wiley & Sons. This book was released on 2013-05-02 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 173. The ocean's meridional overturning circulation (MOC) is a key factor in climate change. The Atlantic MOC, in particular, is believed to play an active role in the regional and global climate variability. It is associated with the recent debate on rapid climate change, the Atlantic Multi-Decadal Oscillation (AMO), global warming, and Atlantic hurricanes. This is the first book to deal with all aspects of the ocean's large-scale meridional overturning circulation, and is a coherent presentation, from a mechanistic point of view, of our current understanding of paleo, present-day, and future variability and change. It presents the current state of the science by bringing together the world's leading experts in physical, chemical, and biological oceanography, marine geology, geochemistry, paleoceanography, and climate modeling. A mix of overview and research papers makes this volume suitable not only for experts in the field, but also for students and anyone interested in climate change and the oceans.
Download or read book Natural Climate Variability on Decade to Century Time Scales written by National Research Council and published by National Academies Press. This book was released on 1996-08-30 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reflects the current state of scientific knowledge about natural climate variability on decade-to-century time scales. It covers a wide range of relevant subjects, including the characteristics of the atmosphere and ocean environments as well as the methods used to describe and analyze them, such as proxy data and numerical models. They clearly demonstrate the range, persistence, and magnitude of climate variability as represented by many different indicators. Not only do natural climate variations have important socioeconomic effects, but they must be better understood before possible anthropogenic effects (from greenhouse gas emissions, for instance) can be evaluated. A topical essay introduces each of the disciplines represented, providing the nonscientist with a perspective on the field and linking the papers to the larger issues in climate research. In its conclusions section, the book evaluates progress in the different areas and makes recommendations for the direction and conduct of future climate research. This book, while consisting of technical papers, is also accessible to the interested layperson.

Download or read book Beyond El Ni o written by Antonio Navarra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interest and level of research into climate variability has risen dramatically in recent years, and major breakthroughs have been achieved in the understanding and modelling of seasonal to interannual climate variability and prediction. At the same time, the documentation of longer term variability and its underlying mecha nisms have progressed considerably. Within the European Commission's Environment and Climate research programs several important projects have been supported in these areas - including the "Dec adal and Interdecadal Climate variability Experiment" (DICE) which forms the basis of this book. Within the EC supported climate research, we see an increasing importance of research into climate variability, as is evidenced in the upcoming Fifth Framework Programme's Key Action on Global Change, Climate and Biodi versity. This is because of the obvious potential socio-economic benefits from sea sonal to decadal scale climate prediction and equally important for the fundamental understanding of the climate system to help improve the quality and reliability of future climate change and mankind's current interference with it. The DICE group has performed important and pioneering work, and we hope this book will receive the wide distribution and recognition it deserves. We wel come the contributions from distinguished researchers from US, Japan and Canada to the EC's DICE group towards completing the scope of the book and as an exam ple of international cooperation which is essential in such a high-level scientific endeavor.
Download or read book Coupled Atmosphere Ocean Dynamics written by Shang-Ping Xie and published by Elsevier. This book was released on 2022-12-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupled Atmosphere-Ocean Dynamics of Climate Variability and Climate Change presents the patterns, mechanisms, and predictability of climate variability and anthropogenic climate change. Based on a graduate course the author has taught over 25 years, this book provides the physical foundation for those who are interested in fundamental questions such as: why climate varies from one year to another; how predictable climate is; and how climate will change in the face of increasing greenhouse gases in the atmosphere. This is the first comprehensive and systematic treatment of this subject that simultaneously draws on the latest research and is accessible for graduate students. The book takes a step-by-step systematic approach to coupled ocean-atmosphere interactions. This allows a wide range of comparative views: climate modes among and across different tropical ocean basins, ocean feedback on the atmosphere (in and out of the tropics), and spontaneous internal oscillation versus externally forced climate change. Such comparative views offer unprecedented insight into the dynamics of climate variability and predictability. This book can be used as supplementary reading for advanced undergraduate students, as coursework in climate dynamics, modeling, variability, and change, and as a reference book and research monograph for researchers in ocean, atmospheric, climate, and earth system sciences. - Delivers the first authored textbook on ocean-atmosphere interactions that give rise to climate variability/predictability and shape regional patterns of anthropogenic climate change - Contains historical accounts of major breakthroughs in the field - Includes homework questions, helping to reinforce key concepts and applications
Download or read book A Multi scale Study of the Dynamical Processes of the Tropical Pacific Ocean written by Autumn Noel Kidwell and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, it has been observed that there are different types of El Niño events. The warm events can be divided into two categories: those centered in the central Pacific (CP) and those centered in the eastern Pacific (EP). We examined the variability of western Pacific warm pool (WP) horizontal migration and size from January 1982 to December 2011 by applying Ensemble Empirical Mode Decomposition (EEMD) and Hilbert Huang Spectrum (HHS) to the optimally interpolated sea surface temperature (OISST) data set. The analysis shows that the long-term residual trend of the zonal centroid movement is migrating to the west by 3.78° from the mean location during the past 30 years. The size of the warm pool has also increased 18% during this period. These analysis techniques isolated two separate time series for the migration of the zonal component of the WPWP for both CP and EP events and showed that these two types of El Niño generally operate at different time-scales. The EP time-series shows the strong traditional EP El Niño and the transition between strong El Niño conditions and La Niña conditions. The CP time-series shows that CP El Niños occur more often than EP El Niños. The changes of the El Niño type in conjunction with westward drift and increasing warm pool size shows an interesting multidecadal change in the warm pool. To extend the centroid study, we also examine the role of the Western Pacific Warm Pool (WP) in the past thirty years of mixed interannual variability, decadal variability, and climate change. Our analysis method involves a multi-dimensional study of the vertical centroid migration, volume, and heat content of the WP and an application of the advanced time-series analysis technique known as Multidimensional Ensemble Empirical Mode Decomposition (MEEMD). We show the 30-year evolution of the warm pool and how it interacts with the PDO, ENSO, and anthropogenic climate forcing mechanisms. Our results show that the WP increasing in size and increasing in heat content anomaly in response to global warming forcing. The variability of the South Pacific Convergence Zone (SPCZ) is evaluated using ocean surface wind products derived from the ERA-Interim atmospheric reanalysis for the period of 1981-2014 and QuickSCAT satellite scatterometer for the period of 1999- 2009. From these products, indices were developed to represent the SPCZ strength, area, and centroid location. Excellent agreement is found between the indices derived from the two wind products during the QuikSCAT period in terms of the spatiotemporal structures of the SPCZ. The longer ERA-Interim product is used to study the variations of SPCZ properties on intraseasonal, seasonal, interannual, and decadal time scales. The SPCZ strength, area, and centroid latitude have a dominant seasonal cycle. In contrast, the SPCZ centroid longitude is dominated by intraseasonal variability due to MJO influence. The SPCZ indices are all correlated with El Niño-Southern Oscillation indices. Interannual and intraseasonal variations of SPCZ strength during strong El Niño are approximately twice as large as the respective seasonal variations. SPCZ strength depends more on the intensity of El Niño rather than the central vs. eastern-Pacific type. The change from positive to negative PDO around 1999 results in a westward shift of the SPCZ centroid longitude, much smaller interannual swing in centroid latitude, and a decrease in SPCZ area. This study improves the understanding of the variations of the SPCZ on multiple time scales and reveals the variations of SPCZ strength not reported previously. The diagnostics analyses can be used to evaluate climate models to gauge their fidelity. We have analyzed multiple data sets (wind, SST, heat content) in an effort to better understand the the WP and the SPCZ. As a major component of the tropical Pacific Ocean dynamics and global climate dynamics, these two intertwined components are critical to study. This is especially true in the context of global climate change.
