The Hadley Circulation Present Past And Future

The book examines potentially important factors that may have affected the Hadley and Walker Circulations and evaluates changes in the Hadley Circulation and the monsoons as simulated by coupled models of past climate conditions, and predicted future conditions under an enhanced greenhouse effect. This book is meant to serve as a fundamental reference work for current and future researchers, graduate students in the atmospheric sciences and geosciences, and climate specialists involved in interdisciplinary research.

Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s. These orbiters, landers and rovers have generated vast amounts of data that now span a Martian decade (roughly eighteen years). This new volume brings together the many new ideas about the atmosphere and climate system that have emerged, including the complex interplay of the volatile and dust cycles, the atmosphere-surface interactions that connect them over time, and the diversity of the planet's environment and its complex history. Including tutorials and explanations of complicated ideas, students, researchers and non-specialists alike are able to use this resource to gain a thorough and up-to-date understanding of this most Earth-like of planetary neighbours.

This book is the standard reference based on roughly 20 years of research on atmospheric rivers, emphasizing progress made on key research and applications questions and remaining knowledge gaps. The book presents the history of atmospheric-rivers research, the current state of scientific knowledge, tools, and policy-relevant (science-informed) problems that lend themselves to real-world application of the research—and how the topic fits into larger national and global contexts. This book is written by a global team of authors who have conducted and published the majority of critical research on atmospheric rivers over the past years. The book is intended to benefit practitioners in the fields of meteorology, hydrology and related disciplines, including students as well as senior researchers.

Today's greater public awareness of how climate affects our quality of life and environment has created an increasing demand for climatological information. Now this information is available in one convenient, accessible source, The Encyclopedia of Climatology. This comprehensive volume covers all the main subfields of climatology, supplies data on climates in major continental areas and explains what is known about the causes of climatic processes and changes. Contents include articles on bioclimatology, El Niño, climatic models, world regional climates, civilization and climate, climatic variations and the greenhouse effect.

Despite major advances in the observation and numerical simulation of the atmosphere, basic features of the Earth's climate remain poorly understood. Integrating the available data and computational resources to improve our understanding of the global circulation of the atmosphere remains a challenge. Theory must play a critical role in meeting this challenge. This book provides an authoritative summary of the state of the art on this front. Bringing together sixteen of the field's leading experts to address those aspects of the global circulation of the atmosphere most relevant to climate, the book brings the reader up to date on the key frontiers in general circulation theory-including the nonlinear and turbulent global-scale dynamics that determine fundamental aspects of the Earth's climate. While emphasizing theory, as expressed through relatively simple mathematical models, it also draws connections to simulations with comprehensive general circulation models. Topics include the dynamics of storm tracks, interactions between wave dynamics and the hydrological cycle, monsoons, tropical and extratropical dynamics and interactions, and the processes controlling atmospheric humidity. An essential resource for graduate students in atmospheric, ocean, and climate sciences and for researchers seeking an overview of the field, The Global Circulation of the Atmosphere sets the standard for future research in a science that stands at a critical juncture. With a foreword by Edward Lorenz, the book includes chapters by Christopher Bretherton; Kerry Emanuel; Isaac Held; David Neelin; Raymond Pierrehumbert, Hélène Brogniez, and Rémy Roca; Alan Plumb; Walter Robinson; Tapio Schneider; Richard Seager and David Battisti; Adam Sobel; Kyle Swanson; and Pablo Zurita-Gotor and Richard Lindzen.

There is little dispute within the scientific community that humans are changing Earth's climate on a decadal to century time-scale. By the end of this century, without a reduction in emissions, atmospheric CO2 is projected to increase to levels that Earth has not experienced for more than 30 million years. As greenhouse gas emissions propel Earth toward a warmer climate state, an improved understanding of climate dynamics in warm environments is needed to inform public policy decisions. In Understanding Earth's Deep Past, the National Research Council reports that rocks and sediments that are millions of years old hold clues to how the Earth's future climate would respond in an environment with high levels of atmospheric greenhouse gases. Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate system. The report describes past climate changes, and discusses potential impacts of high levels of atmospheric greenhouse gases on regional climates, water resources, marine and terrestrial ecosystems, and the cycling of life-sustaining elements. While revealing gaps in scientific knowledge of past climate states, the report highlights a range of high priority research issues with potential for major advances in the scientific understanding of climate processes. This proposed integrated, deep-time climate research program would study how climate responded over Earth's different climate states, examine how climate responds to increased atmospheric carbon dioxide and other greenhouse gases, and clarify the processes that lead to anomalously warm polar and tropical regions and the impact on marine and terrestrial life. In addition to outlining a research agenda, Understanding Earth's Deep Past proposes an implementation strategy that will be an invaluable resource to decision-makers in the field, as well as the research community, advocacy organizations, government agencies, and college professors and students.

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.
