This book about lightning summarizes the essence of physics and effects of lightning in a non-technical manner and provides an up-to-date description of the phenomenon of lightning in simple language. Starting with the myths related to lightning, the reader is introduced to the mechanism of lightning flashes and their interactions with humans, human-made systems and Earth's environment. Most of the available books on lightning are written for the experts in the field and there is a need for a book that introduces the undergraduate and beginning post graduate students to the subject of lightning and prepares them for more advanced books meant for the experts. This introductory book, which is based on a series of lectures given to undergraduate and postgraduate students in electrical engineering, is intended to fill this need. Tailored to the needs of university students who plan to study electrical engineering, meteorology, environmental or basic physics, it is also a valuable reference resource for laymen who are interested in knowing more on this phenomenon.

The definitive history of the modern climate change era, from an award-winning writer who has been at the centre of the fight for more than thirty years In 1979, President Jimmy Carter was presented with the findings of scientists who had been investigating whether human activities might change the climate in harmful ways. "A wait-and-see policy may mean waiting until it is too late," their report said. They were right -- but no one was listening. Four decades later, we are haunted by the consequences of this inattention, and the years of complacency, obfuscation and denialism that followed. Today, the staggering scale and scope of what we have done to the planet is impossible to ignore: the seasons of fire and flood have crossed into plain view. Fire and Flood is a comprehensive, compulsively readable history of climate change from veteran environmental journalist Eugene Linden. Linden retells the story of the modern climate change era decade by decade, tracking the progress of four ticking clocks: first, the reality of climate change itself; second, advances in scientific understanding; third, the spread of public awareness; and fourth, the business and finance response. Like no previous writer, Linden has drawn together the elements of the biggest story in the world, in a book that it is gripping as history, as economic investigation, and as scientific thriller.

This book traces the evolution of climate change research, which, long dominated by the natural sciences, now sees greater involvement with disciplines studying the socio-cultural implications of change. In their introduction, the editors chart the changing role of the social and cultural sciences, delineating three strands of research: socio-critical approaches which connect climate change to a call for cultural or systemic change; a mitigation and adaption strand which takes the physical reality of climate change as a starting point, and focuses on the concerns of climate change-affected communities and their participation in political action; and finally, culture-sensitive research which places emphasis on indigenous peoples, who contribute the least to the causes of climate change, who are affected most by its consequences, and who have the least leverage to influence a solution. Part I of the book explores interdisciplinarity, climate research and the role of the social sciences, including the concept of ecological novelty, an assessment of progress since the first Rio climate conference, and a 'global village' case study from Portugal. Part II surveys ethnographic perspectives in the search for social facts of global climate change, including climate and mobility in the West African Sahel, and human-non human interactions and climate change in the Canadian Subarctic. Part III shows how collaborative and comparative ethnographies can spin "global webs of local knowledge," describing case studies of changing seasonality in Labrador and of rising water levels in the Chesapeake Bay. These perspectives are subjected to often-amusing, always incisive analysis in a concluding chapter entitled "You Ain't Seen Nothing Yet: a death-defying look at the future of the climate debate." The contributors engage critically with the research subject of 'climate change' itself, reflecting on their own practices of knowledge production and epistemological presuppositions. Finely detailed and sympathetic to a broad range of viewpoints, the book sets out a profile for the social sciences and humanities in the climate change field by systematically exploring methodological and theoretical challenges and approaches.

Composed of two extensive sections, this book surveys important work in climate change science, mainly in the United States, and introduces contributions to the body of science that have arrived on the scene between January 2013 and February 2014. The opening section offers a broad examination of contemporary climate change science, with subsections on the Intergovernmental Panel on Climate Change (IPCC); Earth's energy imbalance and energy flow; carbon dioxide's role in the greenhouse effect; climate forcing, and climate feedbacks; Charles David Keeling and the Keeling Curve; the interfaces of atmosphere with oceans and land; paleoclimates and paleoclimatology; rising sea level; melting glaciers; deforestation; desertification; more violent storms, animal and human migration, extinction of species and more. The second section reviews and assesses the newest contributions to the body of research. Among the topics discussed are current and recent research on rising temperatures; the BEST study; the Global Historical Climatology Network (GHCN) and the National Climatic Data Center (NCDC); current and recent research on climate models, new research on global warming 56 million years ago; ecosystem impacts, projections of future climate and more. This book can be considered a bridge between the volumes of Farmer and Cook's Climate Change Science: A Modern Synthesis, as it arrives between the release of the first volume on the Physical Climate (2013) the second, on Earth's climate history, which is now in preparation. The book benefits a wide audience as its survey of the science of climate change provides an introduction to the subject and a discussion of current research in the field. The book may be used as a refresher for those who have had prior courses in climate science and related fields. Each chapter includes a comprehensive list of references for subjects discussed in the text.

Light Scattering Reviews (vol. 9) is aimed at the description of modern advances in radiative transfer and light scattering. The following topics will be considered: light scattering by atmospheric dust particles and also by inhomogeneous scatterers, the general - purpose discrete - ordinate algorithm DISORT for radiative transfer, the radiative transfer code RAY based on the adding-doubling solution of the radiative transfer equation, aerosol and cloud remote sensing, use of polarization in remote sensing, direct aerosol radiative forcing, principles of the Mueller matrix measurements, light reflectance from various land surfaces. This volume will be a valuable addition to already published volumes 1-8 of Light Scattering Reviews.

This edited volume contains research results presented at the 12th International Symposium Continuous Surface Mining, ISCSM Aachen 2014. The target audience primarily comprises researchers in the lignite mining industry and practitioners in this field but the book may also be beneficial for graduate students.

Landslides and debris flows belong to the most dangerous natural hazards in many parts of the world. Despite intensive research, these events continue to result in human suffering, property losses, and environmental degradation every year. Better understanding of the mechanisms and processes of landslides and debris flows will help make reliable predictions, develop mitigation strategies and reduce vulnerability of infrastructure. This book presents contributions to the workshop on Recent Developments in the Analysis, Monitoring and Forecast of Landslides and Debris Flow, in Vienna, Austria, September 9, 2013. The contributions cover a broad spectrum of topics from material behavior, physical modelling over numerical simulation to applications and case studies. The workshop is a joint event of three research projects funded by the European Commission within the 7th Framework Program: MUMOLADE (Multiscale modelling of landslides and debris flows, www.mumolade.com), REVENUES (Numerical Analysis of Slopes with Vegetations, http://www.revenues-eu.com) and HYDRODRIL (Integrated Risk Assessment of Hydrologically-Driven Landslides, www.boku.ac.at/igt/).

How will future climates be different from today's world-and what consequences will changes in climate have for societies and their development strategies? This book is a primer on the essential science for grasping the workings of climate change and climate prediction. It is accessible for readers with little to no background in science, with an emphasis on the needs of those studying sustainable development. John C. Mutter gives a just-the-facts overview of how the climate system functions and what we know about why changes occur. He recounts the evolution of climatology from the earliest discoveries about Earth's climate to present-day predictive capabilities, and clearly presents the scientific basis of fundamental topics such as climate zones, ocean-atmosphere dynamics, and the long-term cycles from glacial to interglacial periods. Mutter also details the mechanisms of climate change and the ways in which human activity affects global climate. He explains the science behind some known consequences of rising temperatures, such as sea level rise, hurricane behavior, and climate variability. The primer discusses how climate predictions are made and examines the sources of uncertainty in forecasting. Climate Change Science is a straightforward and easy-to-read treatment of the fundamental science needed to comprehend one of today's most important issues.

Improving the reliability of long-range forecasts of natural disasters, such as severe weather, droughts and floods, in North America, South America, Africa and the Asian/Australasian monsoon regions is of vital importance to the livelihood of millions of people who are affected by these events. In recent years the significance of major short-term climatic variability, and events such as the El Nino/Southern Oscillation in the Pacific, with its worldwide effect on rainfall patterns, has been all to clearly demonstrated. Understanding and predicting the intra-seasonal variability (ISV) of the ocean and atmosphere is crucial to improving long range environmental forecasts and the reliability of climate change projects through climate models. In the second edition of this classic book on the subject, the authors have updated the original chapters, where appropriate, and added a new chapter that includes short subjects representing substantial new development in ISV research since the publication of the first edition.

This updated and expanded second edition of a much lauded work provides a current overview of the impacts of climate change on tropical forests. The authors also investigate past, present and future climatic influences on the ecosystems with the highest biodiversity on the planet. Tropical Rainforest Responses to Climatic Change, Second Edition, looks at how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis on to ecological processes, e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of the book is the interaction between humans, climate and forest ecology. The authors, all foremost experts in their fields, explore the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, together with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging. This second edition provides an updated text in this rapidly evolving field. The existing chapters are revised and updated and two entirely new chapters deal with Central America and the effect of fire on wet forest systems. In the first new chapter, the paleoclimate and ecological record from Central America (Lozano, Correa, Bush) is discussed, while the other deals with the impact of fire on tropical ecosystems. It is hoped that Jonathon Overpeck, who has been centrally involved in the 2007 and 2010 IPCC reports, will provide a Foreword to the book.

Through application of the Smoothed Particle Hydrodynamics (SPH) method, this monograph mainly focuses on large deformations and flow failure simulations of geomaterials and movement behavior, which are always involved in geo-disasters. The work covers the theoretical background, numerical techniques, code implementation issues, and many novel and interesting applications. Two-dimensional and three-dimensional SPH models in the framework of both hydrodynamics and solid mechanics are established, with detailed descriptions. The monograph also contains many appealing and practical examples of geo-disaster modeling and analysis, including the fluidized movement of flow-like landslides, lateral spread of liquefied soils, and flow slides in landfills. In the documented SPH simulations, the propagation of geo-disasters is effectively reproduced. Dynamic behaviors of geomaterials during propagation are ascertained, including sliding path, flow velocity, maximum distance reached, and distribution of deposits. In this way, the monograph presents a means for mapping hazardous areas, estimating hazard intensity, and identifying and designing appropriate protective measures.

The first International Conference on Hydraulic Design in Water Resources Engineering held at Southampton University in 1984 brought together engineers interested in channels and channel control structures. It was well attended, very successful and generated papers relating to control and diversion structures, sediment control facilities for headworks and intakes, canals under quasi-steady flow conditions, computer simulation of irrigation and drainage canal systems under unsteady flow conditions, and sediment problems in rivers and the effects of engineering works on the regime of rivers. The success of the first meeting was a major factor in deciding to reconvene the Conference in April 1986, also at Southampton University. The second conference is concerned with the design, constructions and operation of land drainage systems and the wealth of papers received for presentation is an indication of how much this subject has developed in the last few decades. The Conference is intended to bring together as much information as possible in the field of Land Drainage together with forecasts of future developments in this important subject. The Proceedings will provide a unique reference and state-of-the-art presentation to all interested in Land Drainage. The Proceedings incorporate the text of a keynote lecture given by W. H. van der Molen, an eminent researcher. His participation added to the prestige of the Conference and the Editors would like to thank him most sincerely for his contribution.

A variety of optimization and simulation models are now com- monly used to help water resource planners and managers identify, evaluate and predict themultiple impacts from va- rious actions or decisions one can make regarding the deve- lopment and management of a region's water resources. Cur- rent developments in computer technology are making it pos- sible to link these models to programs that provide an in- terface betwe- en the decision maker and their models and compu- ters. The volume discusses how these so-called deci- sion support systems can be best developed and used bythose involved in water resources planning and management.

This book deals in a basic and systematic manner with the fundamentals of random function theory and looks at some aspects related to arrival, vehicle headway and operational speed processes at the same time. The work serves as a useful practical and educational tool and aims at providing stimulus and motivation to investigate issues of such a strong applicative interest. It has a clearly discursive and concise structure, in which numerical examples are given to clarify the applications of the suggested theoretical model. Some statistical characterizations are fully developed in order to illustrate the peculiarities of specific modeling approaches; finally, there is a useful bibliography for in-depth thematic analysis.

The thermodynamics of the atmosphere is the subject of several chapters in most textbooks on dynamic meteorology, but there is no work in English to give the subject a specific and more extensive treatment. In writing the present textbook, we have tried to fill this rather remarkable gap in the literature related to atmospheric sciences. Our aim has been to provide students of meteorology with a book that can playa role similar to the textbooks on chemical thermodynamics for the chemists. This implies a previous knowledge of general thermodynamics, such as students acquire in general physics courses; therefore, although the basic principles are reviewed (in the first four chapters), they are only briefly discussed, and emphasis is laid on those topics that will be useful in later chapters, through their application to atmospheric problems. No attempt has been made to introduce the thermodynamics of irreversible processes; on the other hand, consideration of heterogeneous and open homogeneous systems permits a rigorous formulation of the thermodynamic functions of clouds (exclusive of any consideration of microphysical effets) and a better understanding of the approx imations usually implicit in practical applications."

Lectures in Meteorology is a comprehensive reference book for meteorologists and environmental scientists to look up material on the thermodynamics, dynamics and chemistry of the troposphere. The lectures demonstrate how to derive/develop equations - an essential tool for model development. All chapters present applications of the material including numerical models. The lectures are written in modular form, i.e. they can be used at the undergraduate level for classes covered by the chapters or at the graduate level as a comprehensive, intensive course. The student/instructor can address chapters 2 (thermodynamics) and 4 (radiation) in any order. They can also switch the order of chapter 5 (chemistry) and 6 (dynamics). Chapter 7 (climatology and climate) requires an understanding of all chapters. Chapter 3 (cloud physics) needs basics from chapter 2 to understand the cloud microphysical processes. The governing conservation equations for trace constituents, dry air, water substances, total mass, energy, entropy and momentum are presented, including simplifications and their application in models. A brief introduction to atmospheric boundary layer processes is presented as well. Basic principles of climatology discussed include analysis methods, atmospheric waves and their analytical solutions, tropical and extra-tropical cyclones, classical and non-classical mesoscale circulations, and the global circulation. The atmospheric chemistry section encompasses photolytic and gas-phase processes, aqueous chemistry, aerosol processes, fundamentals of biogeochemical cycles and the ozone layer. Solar and terrestrial radiation; major absorber; radiation balance; radiative equilibrium; radiative-convective equilibrium; and basics of molecular, aerosol and cloud adsorption and scattering and their use in remote sensing are also presented.

Unique among all creatures, further to the increase in its cranial volume from Australopithecus to Homo sapiens, the use of tools and cultural and scientific creativity, the genus Homo is distinguished by the mastery of fire, which since about two million years ago has become its blueprint. Through the Holocene and culminating in the Anthropocene, the burning of much of the terrestrial vegetation, excavation and combustion of fossil carbon from up to 420 million years-old biospheres, are leading to a global oxidation event on a geological scale, a rise in entropy in nature and the sixth mass extinction of species.

This monograph provides state-of-the-art theoretical and computational findings from investigations on physical and chemical dissolution front instability problems in porous media, based on the author s own work. Although numerical results are provided to complement theoretical ones, the focus of this monograph is on the theoretical aspects of the topic and those presented in this book are applicable to a wide range of scientific and engineering problems involving the instability of nonlinear dynamic systems. To appeal to a wider readership, common mathematical notations are used to derive the theoretical solutions. The book can be used either as a useful textbook for postgraduate students or as a valuable reference book for computational scientists, mathematicians, engineers and geoscientists."

Climate is a paradigm of a complex system. Analysing climate data is an exciting challenge, which is increased by non-normal distributional shape, serial dependence, uneven spacing and timescale uncertainties. This book presents bootstrap resampling as a computing-intensive method able to meet the challenge. It shows the bootstrap to perform reliably in the most important statistical estimation techniques: regression, spectral analysis, extreme values and correlation. This book is written for climatologists and applied statisticians. It explains step by step the bootstrap algorithms (including novel adaptions) and methods for confidence interval construction. It tests the accuracy of the algorithms by means of Monte Carlo experiments. It analyses a large array of climate time series, giving a detailed account on the data and the associated climatological questions. "....comprehensive mathematical and statistical summary of time-series analysis techniques geared towards climate applications...accessible to readers with knowledge of college-level calculus and statistics." (Computers and Geosciences) "A key part of the book that separates it from other time series works is the explicit discussion of time uncertainty...a very useful text for those wishing to understand how to analyse climate time series." (Journal of Time Series Analysis) "...outstanding. One of the best books on advanced practical time series analysis I have seen." (David J. Hand, Past-President Royal Statistical Society)

Mathematical models are the effective tool to solve different tasks predicting pollutant movement. The finite difference method is the oldest, but still remains widely used in hydrogeological practice. However, this method is not very useful to construct the new transport models because it cannot approximate the shape of remediation elements exactly. Therefore the book is concerned with the FEM (Finite Element Method) and BEM (Boundary Element Method), and also with the comparison of advantages of these methods in groundwater hydrology. The combination of the BEM and the random-walk particle tracking method, which seems to be a very useful tool to model the spread of pollution in groundwater, are also presented. The computer programmes have been developed on the basis of the theoretical backgrounds of these methods. They use the Visual C++ programming language for Windows 95/NT platform and will be included in the book.

The Upper Adriatic Sea basin comprises a very precarious coastal environment subject to continuous changes which prove appreciable not only over the geological scale but also in historical and modern times. According to some Authors the Venice Lagoon was formed 2000-3000 years ago, and other lagoons (e. g. the Grado Lagoon in the northernmost part of the Adriatic) are even more recent. In addition to lagoons, the Upper Adriatic coastal area includes salt and fresh-water marshes and reclaimed land separated by several watercourses originating from the Alpine and Apennine ranges with a ground elevation not exceeding in many places 2 m above the mean sea l. evel (msl). A significant fraction of this lowland is already now below msl because of natural and anthropogenic land subsidence, land reclamation and sea level rise occurred over the last century. Natural land subsidence is still under way as a result of deep downward tec tonic movement and consolidation of soils deposited in the most recent time. An thropogenic subsidence is primarily due to groundwater pumping for agricultural, industrial, civil, and tourist use, and to gas withdrawal from a large number of gas fields scattered through the Upper Adriatic basin, and may still continue, al though at a reduced rate, in the years to come. At the same time msl is expected to rise in the next century due to global climate change, mainly because of the greenhouse effect.

The development of water resources has proceeded at an amazing speed around the world in the last few decades. The hydraulic engineer has played his part: in constructing much larger artificial channels than ever before, larger and more sophisticated control structures, and systems of irrigation, drainage and water supply channels in which the flow by its nature is complex and unsteady requiring computer-based techniques at both the design and operation stage. It seemed appropriate to look briefly at some of the developments in hydraulic design resulting from this situation. Hence the idea of the Conference was formed. The Proceedings of the Conference show that hydraulic engineers have been able to acquire a very substantial base of design capability from the experience of the period referred to. The most outstanding development to have occurred is in the combination of physical and mathematical modelling, which in hydraulic engineering has followed a parallel path to that in other branches of engineering science. The Proceedings of this Conference will give to the reader an awareness of the current state of hydraulic design in open channel flow and open channel control structures. K.V.H. Smith Editor 1.

How to interpret meteorological measurements made at a given level over a surface with regard to characteristic properties such as roughness, albedo, heat, moisture, carbon dioxide, and other gases is an old question which goes back to the very beginnings of modern micrometeorology. It is made even more challenging when it is unclear whether these measurements are only valid for this point/region and precisely describe the conditions there, or if they are also influenced by surrounding areas. After 50 years of field experiments, it has become both apparent and problematic that meteorological measurements are influenced from surfaces on the windward side. As such, extending these measurements for inhomogeneous experimental sites requires a quantitative understanding of these influences. When combined with atmospheric transport models similar to air pollution models, the footprint concept a fundamental approach introduced roughly 20 years ago provides us with information on whether or not the condition of upwind site homogeneity is fulfilled. Since these first models, the development of more scientifically based versions, validation experiments and applications has advanced rapidly. The aim of this book is to provide an overview of these developments, to analyze present deficits, to describe applications and to advance this topic at the forefront of micrometeorological research.

Earthquake and tsunami disasters have been increasing rapidly and globally in the last quarter-century. The purpose of this book is to provide essential knowledge and information on the mitigation of earthquakes and tsunamis for graduate students, young researchers, and geotechnical engineers. It begins by presenting recent cases of earthquakes that have occurred in the world, referring to tsunamis and soil liquefaction and how to cope with such disasters. The final chapter proposes strategies for disaster mitigation against in Japan earthquakes and tsunamis in the future.

The northward migration of the African monsoon rains in summer, associated with the seasonal march of the Intertropical Convergence Zone (ITCZ) across the plains south of the Sahara, is the most critical asset for the livelihoods of indigenous peoples and local economies of the Sahel. It is essential that climate science (and its publicly available database) play a key role in characterizing the variabilities of these rainfall patterns in space and time if sustainable life styles are to accommodate the expanding populations of the region. This study turns to the East Sahel of Sudan by analyzing over 100 years of historical rainfall data from three of the few long term standard WMO rain gauge stations in substantially different rainfall settings. From north to south, transecting the Sahel, the stations with their annual rainfall are Khartoum (130 mm); Kassala (280 mm); and Gedaref (600 mm). The conclusions challenge a popular notion that changing climate, drought and desertification in the East Sahel may have already accelerated the deterioration of its water resources. However, any evidence of a persistent and coherent regional trend of diminishing rainfall is obscure. Quite the contrary, the evidence demonstrates that the fluctuations of climate and weather patterns over the ensuing decades of the past century -at all temporal scales from days to years to decades - profoundly overwhelm any suggestion of a large-scale, coherent decrease (or increase) in rainfall. The implication is that, it is not long term change, but the highly localized interseasonal, interannual and multiannual variability of rainfall that poses the greatest and most immediate societal threat from naturally-induced causes; a process constantly destabilizing an agrarian economy struggling to survive in a climate that irregularly vacillates between years of drought and years of flooding. While this report may have some interest for climate scientists, it is primarily directed to a general readership (including students in public policy and anthropology) concerned with the availability of water in the Sahel, particularly the long term sustainability of local small-scale farms and transhumant pastoralism.
