The US Department of Commerce estimates that nearly 10% of the US's $9 trillion GDP is exposed to weather risk. All over the world providers and end users are recognizing this fact and are turning their attention to ways of protecting against or taking advantage of changes in the weather. This book explores a market that is expected to expand rapidly and is one of the fastest areas of growth in the financial arena.

The development of numerical integration techniques and the pioneering efforts of Von Neumann and his associates at the Institute for Advanced Studies (Princeton) have spurred the renewed interest of many leading fluid dynamicists and meteorologists in the theory and numerical simulation of planetary atmosphere and oceans circulations. Their work during the last 15 years, now culminating in the Global Atmospheric Research Program, has led to the possibility of vastly improved weather forecasts as wei I as the development of a ful I fledged branch of the physical sciences: geophysical fluid dynamics. Simultaneously, great strides have been made in developing new instruments, operating from earth orbiting satel I ites, to powerful observe the meteorological phenomena and to determine the state of motion of the atmosphere. Centre National d'Etudes Spatiales (CNES) of France has very significantly contributed to this effort by developing the EOLE navigation and data collection satell ite, launched on 16 August 1971 to interrogate 500 instrumented platforms measuring meteorological para meters. It is fitting then, that CNES should have brought together lead ing scientists in the field of dynamic meteorology, to participate in its 1970 Summer School on Space Physics."

Meteorology can seem like a black art with the meteorologist producing forecasts that seem to contradict what you are reading from the charts. "The Sailor's Book of the Weather" takes the confusion out of the forecasts and helps you answer, 'Why is that happening?'

"The Sailor's Book of the Weather" introduces key principles that influence the weather and gives the sailor the tools to forecast from observations and make the most of the available information. Wind, clouds and knowledge of weather patterns and local conditions all contain ample hints to allow the informed mariner to accurately predict the weather.

Illustrated with charts and over 100 beautiful photographs, this book is a must for anyone who ventures onto the water, whatever your vessel or experience. It should be carried aboard every boat and is essential reading whether you are on the water, in land, on the coast or venturing further afield.

In this thesis, a new lidar (light detection and ranging) ceilometer capable of monitoring cloud base and sensitive to boundary layer aerosols is introduced. The key to this novelty lies in its divided-lens design that addresses a classical lidar problem of balancing transmitter-receiver overlap and signal-to-noise ratio, along with a method for characterizing overlap in the laboratory. Enhanced sensitivity in the near-range of the instrument is achieved without compromising signal-to-noise in a design that is straightforward to manufacture for broad deployment. The instrument, its optical characterization, and its performance in the field are described. The prototype instrument described here has since formed the basis of a commercial sensor for monitoring clouds and aerosols. High-resolution, continuous observations of clouds and aerosols are needed to reduce the large uncertainties in our current understanding of their influence on climate that have been highlighted by the International Panel on Climate Change. And as international health organizations indicate growing public health threats over the coming decades resulting from poor air quality, extensive aerosol monitoring is required to assess personal exposure to and the health impacts of anthropogenic particulates. Ground-based optical remote sensing measurements made by well-characterized instruments, such as that described in these pages, are critical to this.

Prof. Leon Mestel has been an inspiration to many to study the role of magnetism in the Cosmos. To mark the occasion of his retin'ment from the University of Sussex after 43 years in astrophysics, several of his friends and former students decided to hold an advanced research workshop in his honour. NATO agreed to finance this venture which was held at the Institute of Astronomy at Cambridge. The scientific organizing committee was J. Landstreet, D. Lynden-Bell, F. Pacini, M.A. Rud0rman and N.O. Weiss and most leading experts on Cosmical magnetism agreed to come. We are particularly grateful to Lyman Spitzer who, ably helped by his wife Doreen, !!;ave the after dinner addre~s on how the goddess Astrophysica had foreseen Leon's achievements in classical Greek times. Not without regret we decided to maintain the homog0neity of the material and therefore could not cover Leon Mestel's major achievements in non-magnetic astronomy. His work on the cooling of white dwarfs, his understanding that degenerate hydrogen was a nuclear explosive since its pressure was almost independent of temperature and hence, his picture of supernovae, which is now more commonly applied to novae, his seminal understanding of the 'law' of galactic rotation and his work on the non-linear development of t hp anisotropies generated in gravitational collapse.

The effects of meteorological phenomena upon forest produc tivity and forestry operations have been of concern for many years. With the evolution of system-level studies of forest eco system structure and function in the International Biological Program and elsewhere, more fundamental interactions between forest ecosystems and the atmosphere received scientific atten tion but the emphasis on meteorological and climatological effects on forest processes remained. More recently, as recogni tion has developed of potential and actual problems associated with the atmospheric transport, dispersion, and deposition of airborne pollutants, the effects of forest canopies upon boundary-layer meteorological phenomena has come under scientific scrutiny. Looking to the future, with rising atmospheric con centrations of C02 and increasing competition for the finite fresh-water resources of the earth, interest in the role of forests in global C02 and water balances can also be expected to intensify. Thus, the nature of forest canopy-atmosphere interac tions, that is to say, the meteorological phenomena occurring in and above forest canopies, are of importance to a wide variety of scientific and social-issues. Demands for forest meteorological information currently exceed levels of knowledge and given the economic constraints of science in general and environmental sciences in particular, chances for major improvements in scien tific support in the near future are slim. Unfortunately, studies of environmental phenomena in and above forests are costly and logistically difficult. Trees, the ecological dominants of forest ecosystems, are the largest of all terrestrial organisms."

The Forest Primary Production Research Group was born in the Department of S- viculture, University of Helsinki in the early 1970s. Intensive ?eld measurements of photosynthesis and growth of forest vegetation and use of dynamic models in the interpretation of the results were characteristic of the research in the group. Electric instrumentation was based on analogue techniques and the analysis of the obtained measurements was based on self-written programs. Joint research projects with the Research Group of Environmental Physics at the Department of Physics, lead by Taisto Raunemaa (1939-2006) started in the late 1970s. The two research groups shared the same quantitative methodology, which made the co-operation fruitful. Since 1980 until the collapse of the Soviet Union the Academy of Finland and the Soviet Academy of Sciences had a co-operation program which included our team. The research groups in Tartu, Estonia, lead by Juhan Ross (1925-2002) and in Petrozawodsk, lead by Leo Kaipiainen (1932-2004) were involved on the Soviet side. We had annual ?eld measuring campaigns in Finland and in Soviet Union and research seminars. The main emphasis was on developing forest growth models. The research of Chernobyl fallout started a new era in the co-operation between forest ecologists and physicists in Helsinki. The importance of material ?uxes was realized and introduced explicitly in the theoretical thinking and measurements.

During the last 20 years the study of, and the prediction of, changes in the climate of our planet have become an urgent social imperative, addressed to scientists the world over. The first principles on which to base such a study were formulated in 1974 in Stockholm, at the international GARP conference on the physical fundamentals of climate theory and climate modeling. In 1979 the World Meteorological Organization and the International Council of Scientific Unions decided to conduct a global program of climate research. This World Climate Program is designed mainly to investigate the variability of the climate on time scales ranging from a few weeks to a few decades and to create a scientific basis for the long-term forecasting of weather. There is at present a definite need for a monograph which can serve as an introduction to the theory of climate. On a qualitative level (without the apparatus of theoretical physics and mathematics) such an introduction has already been presented, in Part I of a book on the history of climate by Yu. A. Shishkov and the author (Monin and Shishkov, 1979). Part II of that work gives factual data on climatic changes during the course of the Earth's history. The present book is designed to provide such an introduction on a quantita tive level."

Unique properties of laser radiation including its monochromatic properties, polarization, high spectral intensity, coherence, narrow beam divergence, the possibility of controlling the pulse duration and radiation spectrum and, finally, the fact that extremely high power and energy create very favorable conditions for the extensive application of lasers to communi cation systems, systems for the lidar sensing and ultra-high-precision ranging, navigation, remote monitoring of the environment, and many other systems operating in the atmosphere. The operative efficiency of the above systems depends significantly on the state of the atmosphere and the corresponding behavior of laser radia tion propagating through it. This circumstance has stimulated the studies of the above regularities during the passt 10-15 years. For the investiga tions to be carried out the scientists were forced to develop new theories and methods for studying the problem experimentally. Moreover, during such investigations some previously unknown phenomena were observed, among them the nonlinear effects accompanying high-power laser radiation propagating through the atmosphere are of paramount importance. Among the nonlinear effects caused by high-power laser radiation inter action with the atmosphere, the effects accompanying the propagation of high-power radiation through the atmospheric aerosols are of particular interest. Aerosols always occur in the atmosphere. It should be noted that the microphysical and optical characteristics of atmospheric aerosols vary widely, this fact causes a great variety in the features of their inter action with radiation."

Major themes covered are: Nature and theory of turbulent boundary layers; Boundary layer flows a" modelling and applications to environmental security; Nature, theory and modelling of boundary-layer flows; and Air flows within and above urban and other complex canopies a" air-sea-ice interactions.

The NATO Advanced Research Workshop, held in Dubrovnik, Croatia, 18-22 April 2006, that gave rise to this, book was attended by 57 scientists drawn from 21 countries on four continents. In recognition of his outstanding career and reaching the milestone age of 70, the workshop was dedicated to Professor Sergej Zilitinkevitch and a substantial number of contributions are based on or linked to his fundamental work.

The book presents a collection of articles devoted to atmospheric and ionospheric science reported during the Conference "Atmosphere, Ionosphere, Safety" held in Kaliningrad, Russia in July 2010. It consists of reviews devoted to physics of elementary processes, aerosols, ionosphere dynamics, microwave discharges and plasmoids. Such a wide range of topics presents a comprehensive analysis of this atmospheric science including trends and questions which exist to be solved.

This book examines the approaches to climate change adaptation in water governance taken by South Korea and Germany. By comparing their political decision-making processes, this book explores the factors behind their differences. Adaptation to the changing climate is critical to human society and water is the principal medium through which climate change will affect us. Due to high levels of industrialization and population density, flood control is a high priority in both countries' adaptation plans. While South Korea has maintained its engineering-oriented flood control policy for river management, Germany has turned its direction from its long-standing technical approach to more nature-based solutions. The evidence of this study indicates that policy change and stability is the result of discourse and institutional interaction, and thus emphasizes the validity of discursive institutionalism. This book will clearly explain why certain policies are adopted for water management and will be an invaluable contribution to the expanding literature on the socio-political aspects of climate change adaptation.

The main purpose of this book is to introduce the reader to the subject of solar activity and the connection with Earth's climate. It commences with a brief review of the historical progress on the understanding of the solar-terrestrial connection and moves on to an objective scrutiny of the various hypothesis. The text focuses on how knowledge about the solar cycle and Earth's climate is obtained. It includes discussion of observations, methods and the physics involved, with the necessary statistics and analysis also provided, including an examination of empirical relations between sunspots and the Earth's climate. The author reviews plausible physical mechanisms involved in any links between the solar cycle and the Earth's climate, emphasizing the use of established scientific methods for testing hypothesized relationships.

Around the world, extreme weather events are becoming increasingly "the new normal" and are expected to increase in the 21st century as a result of climate change. Extreme weather events have devastating impacts on human lives and national economies. This book examines ways to protect people from hazards using early warning systems, and includes contributions from experts from four different continents representing 14 different universities, 8 government agencies and two UN agencies. Chapters detail critical components of early warning systems, ways to identify vulnerable communities, predict hazards and deliver information. Unique satellite images illustrate the transnational impact of disasters, while case studies provide detailed examples of warning systems. With contributors from the fields of economics, ethics, meteorology, geography and biology, this book is essential reading for anyone interested in disaster risk reduction or climate change.

This book describes the latest advances, innovations and applications in the field of waste management and environmental geomechanics as presented by leading researchers, engineers and practitioners at the International Conference on Sustainable Waste Management through Design (IC_SWMD), held in Ludhiana (Punjab), India on November 2-3, 2018. Providing a unique overview of new directions, and opportunities for sustainable and resilient design approaches to protect infrastructure and the environment, it discusses diverse topics related to civil engineering and construction aspects of the resource management cycle, from the minimization of waste, through the eco-friendly re-use and processing of waste materials, the management and disposal of residual wastes, to water treatments and technologies. It also encompasses strategies for reducing construction waste through better design, improved recovery, re-use, more efficient resource management and the performance of materials recovered from wastes. The contributions were selected by means of a rigorous peer-review process and highlight many exciting ideas that will spur novel research directions and foster multidisciplinary collaboration among different waste management specialists.

The Southern Hemisphere commands an increasing interest among atmospheric chemists. It has smaller and less industrialized continents than the Northern Hemisphere and thus enjoys lower emissions of anthropogenic and biogenic pollu tants. As a consequence, the concentrations of trace species are lower in the Sou thern Hemisphere, giving rise to significant inter-hemispheric gradients. From an observation of the climatology of the various trace gas gradients important conclu sions on the chemical lifetimes, the distribution of sources and transport of trace species can be derived. Thus it is only fitting that the CSIRO Division of Atmos pheric Research, Aspendale, Australia, hosted the Conference on the Scientific Application of Baseline Observations of Atmospheric Composition (SABOAC). It was convened by Dr Graeme Pearman of the CSIRO and sponsored by the CSIRO and the Australian Bureau of Meteorology. Graeme Pearman and Ian Galbally of the CSIRO also agreed to serve as Guest Editors. The Conference was well attended and because of its location enjoyed an un usually large number of participants from the Southern Hemisphere. About 40 papers were presented with a large share of original contributions. At this point we would like to thank the reviewers who helped to maintain strict standards. The con ference topics ranged from Nonreactive Gases, Reactive Gases, Transport, Parti culates, Precipitation Chemistry, to Radiation and Carbondioxide. The present Proceedings do not quite maintain that sequence but partly reflect the order of receipt. DIETER EHHALT 3 Journal of Atmospheric Chemistry 3 (l985), 3-27."

The Second International Symposium on Constitutive Modeling of Geomaterials: Advances and New Applications (IS-Model 2012), is to be held in Beijing, China, during October 15-16, 2012. The symposium is organized by Tsinghua University, the International Association for Computer Methods and Advances in Geomechanics (IACMAG), the Committee of Numerical and Physical Modeling of Rock Mass, Chinese Society for Rock Mechanics and Engineering, and the Committee of Constitutive Relations and Strength Theory, China Institution of Soil Mechanics and Geotechnical Engineering, China Civil Engineering Society. This Symposium follows the first successful International Workshop on Constitutive Modeling held in Hong Kong, which was organized by Prof. JH Yin in 2007.

Constitutive modeling of geomaterials has been an active research area for a long period of time. Different approaches have been used in the development of various constitutive models. A number of models have been implemented in the numerical analyses of geotechnical structures. The objective of the symposium is to provide a forum for researchers and engineers working or interested in the area of constitutive modeling to meet together and share new ideas, achievements and experiences through presentations and discussions. Emphasis is placed on recent advances of constitutive modeling and its applications in both theoretic and experimental aspects.

Six famous scholars have been invited for the plenary speeches of the symposiums. Some prominent scholars have been invited to organize four specialized workshops on hot topics, including Time-dependent stress-strain behavior of geomaterials, Constitutive modeling within critical state soil mechanics, Multiscale and multiphysics in geomaterials, and Damage to failure in rock structures . A total of 49 papers are included in the above topics. In addition, 51 papers are grouped under three topics covering Behaviour of geomaterials, Constitutive model, and Applications .

The editors expect that the book can be helpful as a reference to all those in the field of constitutive modeling of geomaterials.

There are chapters pertaining to farmer's perception on the impact of climate change, as well discussion on land use change and ecological implications. Many geographical areas are covered including; the Mahananda River Basin, Pindar Basin, Kumaun Himalaya, the Upper Tapi River Basin, Southern Kerala Districts, Uttar Pradesh, Karnataka State, Telangana State, Tamil Nadu State, to name a few.

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.

This book is written by the world's leading climatologists and environmental scientists. It addresses many of the issues raised in the debate on global change, providing a new point of view on climate which is being integrated into the space and time organization of societies. The volume contains three main parts: 1. Climatic Changes and Fluctuations; 2. Climates on a Regional Scale, including problems from tropical through temperate zones to polar regions; and 3. Man-Climate Relationships on a Local Scale. Global change is caused mainly by climatic variation and change and activities of human societies. This book aims to describe these facts from the various space scales - global, regional and local - and also different time scales - post-glacial, historical and recent periods. Since climate affects all kinds of human activities such as agriculture, forestry, architecture, civil engineering, transportation, tourism, health, etc., this book may contribute to the work of researchers, planners and policy makers in a wide variety of fields. For example, as indicated by the IPCC 1995 Report, adjustment of human societies is considered to be one of the most important features in the 21st Century. For consideration of these past, present and future problems, this book will provide, in a systematic way, numerous sources of up-to-date knowledge.

This book is about making weather warnings more effective in saving lives, property, infrastructure and livelihoods, but the underlying theme of the book is partnership. The book represents the warning process as a pathway linking observations to weather forecasts to hazard forecasts to socio-economic impact forecasts to warning messages to the protective decision, via a set of five bridges that cross the divides between the relevant organisations and areas of expertise. Each bridge represents the communication, translation and interpretation of information as it passes from one area of expertise to another and ultimately to the decision maker, who may be a professional or a member of the public. The authors explore the partnerships upon which each bridge is built, assess the expertise and skills that each partner brings and the challenges of communication between them, and discuss the structures and methods of working that build effective partnerships. The book is ordered according to the "first mile" paradigm in which the decision maker comes first, and then the production chain through the warning and forecast to the observations is considered second. This approach emphasizes the importance of co-design and co-production throughout the warning process. The book is targeted at professionals and trainee professionals with a role in the warning chain, i.e. in weather services, emergency management agencies, disaster risk reduction agencies, risk management sections of infrastructure agencies. This is an open access book.

Prior to the space age, meteorologists rarely paid particular attention to the height regions above the tropopause. What was known about the upper atmosphere above about 100 km came essentially from ionospheric and geomagnetic research. The region in between, presently known as the middle atmosphere, was almost terra incognita above the height reachable by balloons. It was space research that allowed for the first time direct access to middle and upper atmospheric heights. About 40 years ago, Sidney Chapman coined a new word 'aeronomy' to describe the study of these two height regions. When asked about the difference between aeronomy and meteorology, he allegedly replied: 'it is the same as between astronomy and astrology' . This mild irony indicates the preferred prejudice of many ionospheric physicists and geomagneticians in those days toward meteorology as a descriptive rather than an exact science, in spite of the presence of such giants as Carl Rossby and Hans Ertel.
