Book Synopsis Reconstructing Coupled Atmosphere-ocean Variability Over the Last Millennium by : Walter Andre Perkins
Download or read book Reconstructing Coupled Atmosphere-ocean Variability Over the Last Millennium written by Walter Andre Perkins and published by . This book was released on 2019 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupled interactions between oceans and the atmosphere are fundamental to low-frequency variability of the Earth System. While the instrumental record provides an account of this coupled variability over time, the length of record often hinders investigation of the mechanisms of variability on decadal and longer timescales. Paleoclimate data assimilation offers an objective method to investigate dynamic field variability of the past constrained by climate proxies and climate model information. This dissertation presents results from coupled atmosphere-ocean field reconstructions over the last millennium using online data assimilation (DA). To achieve online DA-based reconstructions, we implement and examine a linear inverse model (LIM) as a climate model forecast approximation to constrain temporal dynamics of coupled fields. We find LIMs skillfully capture underlying dynamics from coupled global climate models (GCMs) for ensemble climate forecasts. Additionally, the efficiency allows us to perform experiments using large ensembles over long periods, which is not possible with GCMs. When employing LIMs as a forecast model for online paleoclimate DA, we find reconstructions display significantly improved consistency for upper-ocean heat content variability and that they maintain dynamical consistency for specific field relationships when less proxy information is available. These reconstructions also validate well against instrumental ocean data for both spatial and aggregate measures. We find that the reconstructed large-scale temperature averages tend to be cooler than previous reconstructions, especially during the early period (1000-1200 C.E.). However, despite cooler global-scale temperatures, we find early periods of decadal-scale warmth over high-latitude Europe in agreement with previous documentary and proxy-based evidence. Overall, the annually-resolved multivariate reconstructions produced in this dissertation present a more comprehensive account of low-frequency atmosphere-ocean variability over the last millennium. Furthermore, the generality of the presented methodology allows for continued refinement of the reconstruction product over time as the availability of proxy information grows and GCMs improve.

Download or read book Next Generation Earth System Prediction written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing economic vitality, protecting the environment, and informing policy choices. Over the past decade, the ability to forecast weather and climate conditions on subseasonal to seasonal (S2S) timescales, i.e., two to fifty-two weeks in advance, has improved substantially. Although significant progress has been made, much work remains to make S2S predictions skillful enough, as well as optimally tailored and communicated, to enable widespread use. Next Generation Earth System Predictions presents a ten-year U.S. research agenda that increases the nation's S2S research and modeling capability, advances S2S forecasting, and aids in decision making at medium and extended lead times.

Book Synopsis Natural Climate Variability on Decade-to-Century Time Scales by : National Research Council
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.

Book Synopsis Global Environmental Change by : National Research Council
Download or read book Global Environmental Change written by National Research Council and published by National Academies Press. This book was released on 1999-09-14 with total page 621 pages. 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.

Book Synopsis Decade-to-Century-Scale Climate Variability and Change by : National Research Council
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.
