Book excerpt: The goal of the project was to determine midlatitude climate predictability associated with tropical-extratropical interactions on interannual-to-interdecadal time scales. Our strategy was to develop and test a hierarchy of climate models, bringing together large GCM-based climate models with simple fluid-dynamical coupled ocean-ice-atmosphere models, through the use of advanced probabilistic network (PN) models. PN models were used to develop a new diagnostic methodology for analyzing coupled ocean-atmosphere interactions in large climate simulations made with the NCAR Parallel Climate Model (PCM), and to make these tools user-friendly and available to other researchers. We focused on interactions between the tropics and extratropics through atmospheric teleconnections (the Hadley cell, Rossby waves and nonlinear circulation regimes) over both the North Atlantic and North Pacific, and the ocean's thermohaline circulation (THC) in the Atlantic. We tested the hypothesis that variations in the strength of the THC alter sea surface temperatures in the tropical Atlantic, and that the latter influence the atmosphere in high latitudes through an atmospheric teleconnection, feeding back onto the THC. The PN model framework was used to mediate between the understanding gained with simplified primitive equations models and multi-century simulations made with the PCM. The project team is interdisciplinary and built on an existing synergy between atmospheric and ocean scientists at UCLA, computer scientists at UCI, and climate researchers at the IRI.

This book was released on 2021-07-27 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupled atmosphere-ocean models are at the core of numerical climate models. There is an extraordinarily broad class of coupled atmosphere-ocean models ranging from sets of equations that can be solved analytically to highly detailed representations of Nature requiring the most advanced computers for execution. The models are applied to subjects including the conceptual understanding of Earth's climate, predictions that support human activities in a variable climate, and projections aimed to prepare society for climate change. The present book fills a void in the current literature by presenting a basic and yet rigorous treatment of how the models of the atmosphere and the ocean are put together into a coupled system. The text of the book is divided into chapters organized according to complexity of the components that are coupled. Two full chapters are dedicated to current efforts on the development of generalist couplers and coupling methodologies all over the world.

Book excerpt: The National Academies' Board on Atmospheric Sciences and Climate (BASC) held a workshop to explore and evaluate current efforts to model physical processes of coupled atmosphere-land-ocean (A-L-O) models. Numerical models of the atmosphere and ocean are central to weather prediction, research, and education. Although great strides have been made over the past few decades in understanding the atmosphere and ocean, modeling capabilities, and numerical A-L-O simulations, some unresolved processes in the models do not adequately represent knowledge of the underlying physics. Moreover, there is evidence that further progress in numerical simulations is being impeded by the slow pace of improvement in the representation of key physical processes in the models and the fact that geophysical flow models are not receiving the attention needed to make these tools more useful and accurate. These models often are used to predict future events, so it is imperative that their underlying physical processes be represented as robustly as possible. During the workshop, the parameterization of physical processes in A-L-O models was addressed, including associated errors, testing, and efforts to improve the use of parameterizations. Participants also examined intellectual and scientific challenges in modeling and highlighted the idea that some of the key impediments to progress in representing physical processes are primarily cultural in nature.

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

Book excerpt: "The Climate Model Development Task Force (CMDTF; 2014-2017) was formed to bring together representatives from National Oceanic and Atmospheric Administration (NOAA) laboratories, the NOAA National Centers for Environmental Prediction (NCEP), and Climate Process Teams research centers and other projects funded by the NOAA Modeling, Analysis, Prediction and Projections (MAPP) program, with an interest in furthering the coupled modeling capability for sub-seasonal to seasonal and longer time scale prediction. The CMDTF provided a platform to discuss model development efforts and best practices. The CMDTF made contributions to the planning process including defining requirements for the transition from operations to research (O2R) and for future model configurations and output, and defining metrics and a test harness for evaluation of climate models and climate predictions. A number of the projects that were engaged in the CMDTF contributed to designing and developing subgrid-scale and land surface process representations, component models, coupling infrastructure, and multi-model combination strategies. The CMDTF served the functions of both keeping the diverse projects in these categories informed of progress and findings as well as stimulating collaboration among these projects"--Executive summary.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book sets forth the physical, mathematical, and numerical foundations of computer models used to understand and predict the global ocean climate system. Aimed at students and researchers of ocean and climate science who seek to understand the physical content of ocean model equations and numerical methods for their solution, it is largely general in formulation and employs modern mathematical techniques. It also highlights certain areas of cutting-edge research. Stephen Griffies presents material that spans a broad spectrum of issues critical for modern ocean climate models. Topics are organized into parts consisting of related chapters, with each part largely self-contained. Early chapters focus on the basic equations arising from classical mechanics and thermodynamics used to rationalize ocean fluid dynamics. These equations are then cast into a form appropriate for numerical models of finite grid resolution. Basic discretization methods are described for commonly used classes of ocean climate models. The book proceeds to focus on the parameterization of phenomena occurring at scales unresolved by the ocean model, which represents a large part of modern oceanographic research. The final part provides a tutorial on the tensor methods that are used throughout the book, in a general and elegant fashion, to formulate the equations.
