This book on electromagnetic resonance phenomena describes a general approach to physical problems, ways to solve them, and properties of the solutions obtained. Attention is given to the discussion and interpretation of formal and experimental data and their links to global atmospheric conditions such as the dynamics of global thunderstorm activity, variations of the effective height of the lower ionosphere, etc.

Schumann resonance is related to worldwide thunderstorm activity, and simultaneously, to global properties of the lower ionosphere. Transverse resonance is predominantly a local phenomenon containing information on the local height and conductivity of the lower ionosphere and on nearby thunderstorm activity.

Transient events in ELF-VLF radio propagation are also treated. These are natural pulsed radio signals and/or abrupt changes of manmade VLF radio signals. The transients associated with cloud-to-ionosphere discharges (red sprites, blue jets, trolls) are discussed, and clarification of the underlying physical ideas and their practical applications to pioneer results achieved in the field recently are emphasised.

IX OVERVIEW Ferdinand Baer Helmut E.

The main objective of the workshop was to increase our knowledge of ozone formation and distribution in the troposphere, its relation to precursor (NO and HC species) distribution, how it is affected by transport processes in the troposphere, and to show how the increasing levels of ozone can cause environmental problem. The focus was on the interaction of ozone on regional and global scales. There is mounting evidence that such interactions occur and that the ozone levels are increasing in most of the Northern Hemisphere tropo sphere. A likely source of ozone increase is human activity. As result of this, tropospheric climate may change significantly within a few decades, either through direct effects by ozone itself or indirectly through its effect on other radiatively active trace species. Further more, ozone may have adverse effects on vegetation over large continental areas due to enhanced levels which have been measured to take place. As it is well known that ozone plays a key role in the oxidation of a large number of chemical species in the troposphere, natural as well as man-made, the atmospheric distribution of important trace species like sulfur dioxide, nitrogen oxides and hydrocarbons could be markedly changed as a result of ozone changes. The rapidly increasing interest in tropospheric ozone, and the key role ozone plays in several atmospheric areas as well the obvious increase in the tropospheric concentration of ozone made ozone a natural choice as a topic for the workshop."

It has been known at least since the end of the century that the polar areas play a very important role in the formation of the Earth's climates. It is also known today that they are the most sensitive regions to climatic change, and are thus perfect case studies for the detection of such changes. The most serious obstacle to the study of climatic and other geographical elements of the polar areas (including the Arctic) has always been the severe climatic conditions which prevail in these regions. Because of these extreme con- tions, research into particular elements of the climatic system (including the atmosphere) began here much later than it did in lower latitudes. For instance, the whole area of the Arctic was not sufficiently covered with a network of meteorological stations until the late 1940s (and even then there were large areas of the central Arctic and the Greenland interior for which no data were available). This is probably why it was not until the start of the 1990s that a body of work began to appear which analysed in any depth climatic variability for the Arctic as a whole. While a considerable number of papers had been p- lished before this period, most of them were local studies presenting highly localised information, providing air temperature measurements but often little else.

Strong atmosphere-hydrology-biosphere feedbacks including human activity affect the rate and sign of changes in the Earth s system and have impacts on socioeconomic relationships. These processes are related to atmospheric circulation, climate and land use changes. Satellite-based and in situ monitoring systems have greatly increased our understanding of variations and changes occurring in the regional climate, atmospheric regime, land cover and water circulation. Coupled numerical models are invoked to describe features, which cannot be caught by observation systems or to predict a future state.

This book summarizes the state-of-the-art researches on land cover, atmosphere and water resources of the Eastern Europe region, sets up priorities of major researches in these fields, outlines deficiencies in data and their processing, and develops recommendations for further research directions. Selected papers of the Non-Boreal Eastern Europe NEESPI meeting cover five topics:

• Observational issues in the non-boreal Eastern Europe
• Regional climate changes
• Air pollution aspects
• Land cover and land use changes
• Changes in the Black Sea and its coastal zone.

In this book the author has succeeded in presenting the many facets of the globel problems and hazards for our climate and thei r i nterdi scip l inary aspects, as we II as maki ng these under- standable for the non-specialist. In doing this, the author has not restricted himself to an analysis of the difficult problems but has indicated the necessity and the possibilities for ratio- na l so lutions. The book, therefore, can be a va lueb le deci si on- aid for all those who directly or indirectly are in positions of responsibi lity at various levels of administration or in industry end busi ness. We ll-timed precauti onary measures agai nst a g loba l deteri o- ration of cLimate are not only necessary for reasons of environ- mental protection. They are also an economical end political necessity. The measures include the reduction of the combustion of fossi l fue ls, a more rati one l energy uti l ization, as we II as the establishment of a global equilibrium between forest loss and reforestati on. The Federal German Government takes these potential anthro- pogenic climate changes very seriously. In order to obtein better scientific information, the Federal Government has ini- ti ated an i nterdi sci p l i nary nati one l Climate Programme. At the same time, the Federal Republic of Germany supports the relevant activities within the frame of international cooperation.

Thirty-six years before Hurricane Katrina ravaged New Orleans and southern Mississippi, the region was visited by one of the most powerful hurricanes ever to hit the United States: Camille.

Mark M. Smith offers three highly original histories of the storm's impact in southern Mississippi. In the first essay Smith examines the sensory experience and impact of the hurricane--how the storm rearranged and challenged residents' senses of smell, sight, sound, touch, and taste. The second essay explains the way key federal officials linked the question of hurricane relief and the desegregation of Mississippi's public schools. Smith concludes by considering the political economy of short- and long-term disaster recovery, returning to issues of race and class.

"Camille, 1969" offers stories of survival and experience, of the tenacity of social justice in the face of a natural disaster, and of how recovery from Camille worked for some but did not work for others. Throughout these essays are lessons about how we might learn from the past in planning for recovery from natural disasters in the future.

Regional Climate of China is the first volume to present the latest research findings gained over the last decade which has greatly advanced our knowledge of the regional climate researches in China. A distinctive feature of the volume is that it is based on an integration of researches by using the advanced technologies, such as field observation and experiment, satellite information and numerical models in the regional climate studies.

One of the principal concerns in recent years regarding the atmospheric environment has been the formation of ozone and other photo-oxidants over much of Europe in the summer. Ozone is formed in the atmosphere by a complex series of chemical reactions in the presence of sunlight from volatile organic compounds and nitrogen oxides. As the reactions take place in air flows determined by the detailed meteorological situation, the measurement, interpretation, understanding and modelling of the levels, fluxes and origins of the ozone are extremely difficult. The present volume reviews several of the currently important questions and presents detailed reports from investigators all over the continent. As such, it provides insight into the current scientific views about ozone in Europe.

This original book describes the behavior of tropical cyclones in the South Pacific. It investigates the broad range of disturbance effects these violent storms have on the physical environments of the islands that lie in their path and the people who live on them. It is the first book to link these two themes the characteristics of cyclones and their landscape impacts. Examples and illustrations are drawn widely from across the region, resulting in a highly readable volume.

In this volume, we present the lectures given during the 1984 OHOLO Conference, held in Zichron Yaacov, Israel. The Conference was organized by the Israel Institute for Biological Research, Department of Mathematics, which is involved in Environmental Risk Evaluation, and in Projects Estimating the Potential of Wind Energy. The lectures cover a broad spectrum of mathematical models, ranging from those that deal with the solution of atmospheric conservation equations, and to those models that yield empirical estimates based on real time measure ments and thus are unique to the locale where measured. The goal of the Conference was to allow scientists from various countries to meet and discuss topics of mutual interest, including the following: 1. Structure of the boundary layer - primarily models dealing in the understanding of the various processes of atmospheric energy transfer, and their influence on the size and composition of the boundary 1 ayer. 2. Advanced mathematical techniques for describing flow and diffusion - lectures on approximations and techniques for solving the diffu sion and transport equations. 3. Flow over complex terrain - research into various aspects of the problem - mathematical models, physical models, experimental results. 4. Models of pollution transport and deposition."

A group of experts developed the outline for the Atmospheric Transport Model Evaluation Study and specified the requirements of modellers for radiological and meterological data. The results of the study are presented in this book.

There are three specific purposes of "Construction Dispute Research. "First, this volume aims to summarise studies on construction dispute. Second, apart from the theoretical constructs, where appropriate empirical tests are also included. This approach serves to go beyond the commonly used anecdotal approach for the subject matters. Third, it is the sincere hope of the authors that this book will help shaping research agenda of construction dispute. The studies are mostly framed from a management perspective drawing on methods and concepts in contract law, economics, psychology and management science.

The book has twenty chapters that are arranged in four parts covering conceptualisation, avoidance, negotiation and mediation. Part 1 is devoted for dispute conceptualisation. A building is only as strong as its foundation. Thus it is no better start to study construction dispute by conceptualisation. The theme of Part 2 is dispute avoidance. The conventional wisdom of 'prevention is better than cure' seems can be applied to all problems. As far as construction dispute is concerned, equitable risk allocation and trust are the two most commonly accepted avoidance strategies. Part 3 focuses on negotiation that is the gateway to resolution as almost all disputes are negotiated first before the service of other mechanisms. Negotiation is sometimes described as an art because settlement may not be obtained solely from legal and rational approaches. Part 3 discusses the behavioral dimensions of construction dispute negotiation. Part 4 deals with Mediation- a form of assisted negotiation. Specially, the skill of the mediators in facilitating settlement, the interrelationships among dispute sources, mediator tactics and mediation outcomes are explored.The studies presented in "Construction Dispute Research" collectively demonstrate holistic approach in dispute management. Each chapter can be read as a study on its own. Practitioners will find the book a handy reference in dispute management and resolution. Students would find the book useful in explaining in details the causes of dispute, the processes to resolve them. The research design and empirical approaches are particularly useful to students in construction management, architectural, surveying and civil engineering programs."

Light scattering by densely packed inhomogeneous media is a particularly ch- lenging optics problem. In most cases, only approximate methods are used for the calculations. However, in the case where only a small number of macroscopic sc- tering particles are in contact (clusters or aggregates) it is possible to obtain exact results solving Maxwell's equations. Simulations are possible, however, only for a relativelysmallnumberofparticles,especiallyiftheirsizesarelargerthanthewa- length of incident light. The ?rst review chapter in PartI of this volume, prepared by Yasuhiko Okada, presents modern numerical techniques used for the simulation of optical characteristics of densely packed groups of spherical particles. In this case, Mie theory cannot provide accurate results because particles are located in the near ?eld of each other and strongly interact. As a matter of fact, Maxwell's equations must be solved not for each particle separately but for the ensemble as a whole in this case. The author describes techniques for the generation of shapes of aggregates. The orientation averaging is performed by a numerical integration with respect to Euler angles. The numerical aspects of various techniques such as the T-matrix method, discrete dipole approximation, the ?nite di?erence time domain method, e?ective medium theory, and generalized multi-particle Mie so- tion are presented. Recent advances in numerical techniques such as the grouping and adding method and also numerical orientation averaging using a Monte Carlo method are discussed in great depth.

Atmospheric Remote Sensing: Principles and Applications discusses the fundamental principles of atmospheric remote sensing and their applications in different research domains. Furthermore, the book covers the basic concepts of satellite remote sensing of the atmosphere, followed by Ionospheric remote sensing tools like Global Positioning System (GPS) and Very Low Frequency (VLF) wave. Sections emphasize the applications of atmospheric remote study in Ionospheric perturbation, fire detection, aerosol characteristics over land, ocean and Himalayan regions. In addition, the application of atmospheric remote sensing in disaster management like dust storms, cyclones, smoke plume, aerosol-cloud interaction, and their impact on climate change are discussed. This book is a valuable reference for students, researchers and professionals working in atmospheric science, remote sensing, and related disciplines.

This book focuses on how climate affects or affected the biosphere and vice versa both in the present and in the past. The chapters describe how ecosystems from the Antarctic and Arctic, and from other latitudes, respond to global climate change. The papers highlight plant responses to atmospheric CO2 increase, to global warming and to increased ultraviolet-B radiation as a result of stratospheric ozone depletion.

Mountains, Climate and Biodiversity A comprehensive and up-to-date synthesis for students and researchers Mountains are topographically complex formations that play a fundamental role in regional and continental-scale climates. They are also cradles to all major river systems and home to unique, and often highly biodiverse and threatened, ecosystems. But how do all these processes tie together to form the patterns of diversity we see today? Written by leading researchers in the fields of geology, biology, climate, and geography, this book explores the relationship between mountain building and climate change, and how these processes shape biodiversity through time and space. In the first two sections, you will learn about the processes, theory, and methods connecting mountain building and biodiversity In the third section, you will read compelling examples from around the world exploring the links between mountains, climate and biodiversity Throughout the 31 peer-reviewed chapters, a non-technical style and synthetic illustrations make this book accessible to a wide audience A comprehensive glossary summarises the main concepts and terminology Readership: Mountains, Climate and Biodiversity is intended for students and researchers in geosciences, biology and geography. It is specifically compiled for those who are interested in historical biogeography, biodiversity and conservation.

On decadal time scales, climate change may result not only from man-made causes, but also from natural processes. This book brings together theoretical conceptions of the physical mechanisms of climate change with observational evidence of these changes. The following key topics are included: Observed Climatic Variability, Predictability of the Atmosphere and Oceans from Days to Decades, and Mechanisms for Decadal to Centennial Climate Variability. Further, there are specialised contributions on the role of the oceanic circulation in climate change. The authors are renowned for their pedagogical skills, and the book is primarily designed for beginners in the field, who have a background in physical science. In addition, it is an invaluable source of information for scientists seeking an overview on climate dynamics.

Climate change is a major environmental concern of regional, national, and international scope, but its inherent uncertainties have often been cited as the main reason for delaying any actions to mitigate its potential impacts. Recent reviews of environmental impact assessments have shown that impacts from climate change have been inadequately addressed and that the corresponding uncertainties have been addressed even more poorly within them. However, this inaction runs completely contrary to the principles of sound risk management, since a proper consideration of the impact from uncertainty increases, rather than decreases, the rationale for preventative action. Irrespective of climate uncertainties, decisions have to be made today and it proves a better course of action to adopt the precautionary principle when making these decisions by recognizing the uncertainties rather than by ignoring them completely. Change Uncertainties in Environmental Assessments demonstrates methods for addressing, incorporating, and communicating the inherent uncertainties surrounding climate change in environmental impact assessments. Clearly, potential impacts from climate change require immediate attention because of the uncertainties, not in spite of them.

This volume is based on a workshop on "Effects of accumulation of air pollutants in forest ecosystems'; held in GOttingen, Federal Republic of Germany, from May 16-18, 1982. This work'shop was initiated and sponsored by the Environmental Agency of the Federal Republic of Germany (project officer: Dr. J. Pankrath) as part of a research contract (project leader: Dr. B. Ulrich). THE PROBLEM SEEN UNDER THE ASPECT OF ADMINISTRATION The problem of forest damage caused by air pollution is not new in Europe. Already in 1983 a comprehensive report from Schroeder and Reuss about vegetation damages by fume in the Harz mountains was published. In 1923, Prof. Dr. Julius Stocklasa of the Bohemian Technical Highschool in Prague was concerned with research of toxical effects of sulphur dioxide in his publication "The damage of vegetation by flue gas and exhalations of facili ties." This comprehensive and instructive work concludes with the sentence: "It is already high time for the governments of all cultural states to take legal, police and private measures in order to prevent damage by flue gases." In the neighbourhood of industries with high gaseous and dust emissions damages have been shown to occur for a long timei these deleterious effects have influenced the growth of trees and in extreme cases have even caused their early death."

Soil carbon sequestration can play a strategic role in controlling the increase of CO2 in the atmosphere and thereby help mitigate climatic change. There are scientific opportunities to increase the capacity of soils to store carbon and remove it from circulation for longer periods of time. The vast areas of degraded and desertified lands throughout the world offer great potential for the sequestration of very large quantities of carbon. If credits are to be bought and sold for carbon storage, quick and inexpensive instruments and methods will be needed to monitor and verify that carbon is actually being added and maintained in soils. Large-scale soil carbon sequestration projects pose economic and social problems that need to be explored. This book focuses on scientific and implementation issues that need to be addressed in order to advance the discipline of carbon sequestration from theory to reality. The main issues discussed in the book are broad and cover aspects of basic science, monitoring, and implementation. The opportunity to restore productivity of degraded lands through carbon sequestration is examined in detail. This book will be of special interest to professionals in agronomy, soil science, and climatology.

The scientific community has voiced two general concerns about the future of the earth. Climatologists and oceanographers have focused on the changes in our physical environment -- changes in the climate, the oceans, and the chemistry of the air we breathe. Environmental biologists, on the other hand, have addressed issues of conservation and the extinction of species. There is increasing evidence that these two broad concerns are intertwined and mutually dependent. Past changes in biodiversity have both responded to and caused changes in Earth's environment. In its discussions of ten key terrestrial biomes and freshwater ecosystems, this volume uses our broad understanding of global environmental change to present the first comprehensive scenarios of biodiversity for the twenty-first century. Combining physical earth science with conservation biology, Global Biodiversity in a Changing Environment provides a starting point for regional assessments on all scales. The book will be of interest to those concerned with guiding research on the changing environment of the earth and with planning future policy, especially in accordance with the Global Biodiversity Convention.

In regions as densely populated as Western Europe, prediction of the ecological implications of pollutant transport are important in order to minimise damage in the case of accidents, and to evaluate the possible influence of existing or planned sources. In most cases, such predictions depend on high-speed computation. The present textbook presents a mathematically explicit introduction in eight chapters: 1: An introduction to the basics of fluid dynamics of the atmosphere and the local events and mesoscale processes. 2: The types of PDEs describing atmospheric flows for limited area models, the problem of appropriate boundary conditions describing the topographical constraints, and well-posedness. 3: Thermodynamics of the atmosphere, dry and wet, its stability, and radiation processes, budgets and the influence of their sum. 4: Scaling and similarity laws for stable and convective turbulent atmospheric boundary layers and the influence of inhomogeneous terrain on the advection and the vertical dispersion, and the method of large eddy simulation. 5: Statistical processes in turbulent dispersion, turbulent diffusion and chemical reactions in fluxes. 6: Theoretical modelling of diffusion and dispersion of pollutant gases. 7: The influence of urban heat production on local climate. 8: Atmospheric inversion layers and lapping inversion, the stable boundary layer and nocturnal inversion.

Part of the excitement in boundary-layer meteorology is the challenge associated with turbulent flow - one of the unsolved problems in classical physics. An additional attraction of the filed is the rich diversity of topics and research methods that are collected under the umbrella-term of boundary-layer meteorology. The flavor of the challenges and the excitement associated with the study of the atmospheric boundary layer are captured in this textbook. Fundamental concepts and mathematics are presented prior to their use, physical interpretations of the terms in equations are given, sample data are shown, examples are solved, and exercises are included.

The work should also be considered as a major reference and as a review of the literature, since it includes tables of parameterizatlons, procedures, filed experiments, useful constants, and graphs of various phenomena under a variety of conditions. It is assumed that the work will be used at the beginning graduate level for students with an undergraduate background in meteorology, but the author envisions, and has catered for, a heterogeneity in the background and experience of his readers.

Climatic Change is a rapidly evolving domain that has prompted the publication of numerous scientific works in recent years, reflecting both the public and scientific interest in the topic. This book focuses upon climate processes, variability and change and applies the general principles related to these issues, particularly in Switzerland. Although a small country, Switzerland is characterized by complex topography where climatic processes are often enhanced due to the presence of the Alps. In addition, there is a remarkable density of observational data in both the natural and social sciences that enable a comprehensive assessment of climate processes, their long-term trends and their impacts.

This book draws upon recent scientific work by the author, as well as by close colleagues working within scientific networks both in Switzerland and Europe, in order to provide the reader with up-to-date information on climate processes in the course of the 20th and 21st centuries.

This book is intended for students from the undergraduate level onwards and researchers interested in climate issues specific to the alpine region.
