This set of conference papers covers such topics as: the need for water to maintain life; the atmospheric water vapour in all layers of the troposphere; the measurement of cloud water contents and the partitionof its liquid and solid phases; and land and ocean nutrients.

In the past decade, there has been a substantial increase of grid-feeding photovoltaic applications, thus raising the importance of solar electricity in the energy mix. This trend is expected to continue and may even increase. Apart from the high initial investment cost, the fluctuating nature of the solar resource raises particular insertion problems in electrical networks. Proper grid managing demands short- and long-time forecasting of solar power plant output.

"Weather modeling and forecasting of PV systems operation" is focused on this issue. Models for predicting the state of the sky, nowcasting solar irradiance and forecasting solar irradiation are studied and exemplified. Statistical as well as artificial intelligence methods are described. The efficiency of photovoltaic converters is assessed for any weather conditions.

"Weather modeling and forecasting of PV systems operation" is written for researchers, engineers, physicists and students interested in PV systems design and utilization.

The "European Experiment on the Transport and Transformation of Environmentally Relevant Trace Constituents over Europe" (EUROTRAC) was established in 1986 to tackle the scientific problem and combine the expertise, knowledge and resources in Europe, in order to apply them over a large region covering the greater part of the continent. EUROTRAC is a coordinated multidisciplinary scientific research project involving field measurements, laboratory studies, instrument development and development of comprehensive computer models for the simulation of the physical and chemical processes in the lower atmosphere.

There have been many excellent books written on the subject of plastic deformation in solids, but rarely can one find a textbook on this subject. "Plasticity Modeling & Computation" is a textbook written specifically for students who want to learn the theoretical, mathematical, and computational aspects of inelastic deformation in solids. It adopts a simple narrative style that is not mathematically overbearing, and has been written to emulate a professor giving a lecture on this subject inside a classroom. Each section is written to provide a balance between the relevant equations and the explanations behind them. Where relevant, sections end with one or more exercises designed to reinforce the understanding of the "lecture." Color figures enhance the presentation and make the book very pleasant to read. For professors planning to use this textbook for their classes, the contents are sufficient for Parts A and B that can be taught in sequence over a period of two semesters or quarters.

The journal Boundary-Layer Meteorology was started in 1970 and has become the premier vehicle for the publication of research papers in its field. Dr R.E. Munn served as Editor-in-Chief until recently. The special 25th Anniversary volume, on which this book is based, was compiled from review and other articles solicited and selected as a Festschrift' to honour Ted Munn's achievement as editor of the journal over that time. Articles by leading contributors to the field include reviews of field studies (Askervein, HEXOS, Cabauw) and their impacts; numerical modelling (large-eddy simulation of the surface layer, frontal structures); analyses and critical discussions (of the von Karman constant, bulk aerodynamic formulations, air-sea interaction, vegetation canopies); and reviews or previews of progress in our understanding of the atmospheric boundary layer, turbulence simulation, Lagrangian descriptions of turbulent diffusion and remote sensing of the boundary layer. The collection provides an excellent perspective on the state of the subject and where it is headed. It should provide fascinating and stimulating reading for researchers and students of boundary-layer meteorology and related areas.

One of the main objectives of the European Community Programme on Solar Energy is to provide solar energy practitioners -- architects and engineers who design and implement both active and passive solar energy systems, including biomass and daylighting systems -- with well documented meteorological and climatological data so that they can estimate the solar radiation falling on a receiving surface for any location and at any time throughout the year. As a complement to its other landmark contributions in providing firm data to the solar energy community, the CEC launched a new, 36-month-long programme on 1 April 1986, which was intended to provide a better understanding of the relationship between climatic factors and solar radiation, determine the effect of anthropogenic pollution on the amount of usable solar energy, and establish sound models for the correlation between weather data, pollution, regional orography, coastal influence and the solar radiation pattern. The current volume presents the results of this research programme, gathered from eight characteristic sites in the EC. The first three chapters deal with the problem in general, present the environmental parameters which influence the radiation climate of a site, and explain the process of modelling microclimate solar radiation for a specific site. Chapter 4 deals with specific methods for evaluating microclimate solar radiation, using both a software package and a pocket calculator. Chapter 5 supplies extensive references.

A quantitative measure of the accuracy of the rate coefficients and the excess energies is a desirable goal of this analysis. There are two major sources of uncertainties: The atomic and molecular data and the solar irradiance. The cross sections and branching ratios used in this analysis come from many different sources; many of them without any error indications. For this reason, we must confine ourselves to a qualitative indication of the reliability of the results. Specifically we give a quality scale in Table II for the data of each mother molecule; A indicating the highest quality of atomic and molecular data and F the lowest quality. The letter B typically means that the threshold is uncertain. For most molecules the cross section at threshold is very small and the rate coefficient for these molecules is therefore not influenced by this uncertainty. For atomic species the cross section is usually large near threshold, but for these species the threshold is known quite accurately. The letter B, therefore, indicates that the rate coefficient is most likely quite accurate, but the excess energy is less accurately known. The letter C usually means that the branching ratios are not well known. This means that the total rate coefficient is very good, but the rate coefficients and the excess energies for the individual branches are less accurate.

This book discusses UV radiation, its effects on ecosystems and the likely evolutionary consequences of changed UV radiation environments, past, present and future. The first two chapters examine the history of the UV radiation climate of earth and the factors that determine organismal and ecosystem exposure. Their purpose is to give the reader a physical perspective on UV radiation and an understanding of the constantly changing UV environment that ecosystems are exposed to over time. Variations in the UV radiation environment occur at the local level (such as boundary layer and plant canopy effects) through to global-scale changes (such as alterations in the column abundance of UV-B protecting ozone). UV radiation regimes also vary over temporal scales. These alterations occur on time scales of seconds (the movement of clouds and plant canopies) to literally billions of years (gross long-term changes in the composition of the Earth's atmosphere). In the chapters that follow five specific biological and ecological topics in photobiology are considered. They are effects of UV radiation on amphibians, plants, corals, aquatic microbial ecosystems and Antarctic ecosystems that are exposed to the anthropogenically generated ozone 'hole'. These chapters consider UV radiation effects at a diversity of levels from the biochemical to the community. Their purpose is to provide the reader with our current understanding of the ecological effects of UV radiation, the areas where questions still remain and to provide a perspective from which the reader can better understand questions in evolutionary photobiology. The final chapter investigates the biological consequences of altered extraterrestrial ultraviolet fluxes, which are quite different from those experienced on the Earth. Our knowledge of the role of UV radiation in shaping ecologies and evolutionary change is still in its infancy. This book brings together a number of authors with the aim of helping to consolidate a better understanding of this interesting area of photobiology.

This book presents an up-to-date analysis of ocean-atmosphere interaction. Well known experts examine diverse subjects such as ocean surface waves, air-sea exchange processes, ocean surface mixed layer, water-mass formation, as well as general circulation of the oceans, El Nino and Southern Oscillation (ENSO), and the deep-ocean circulation. Other areas described are basic dynamics, data analysis techniques, numerical modelling, and remote sensing.

This book is primarily aimed at graduate and senior undergraduate courses in the area of ocean-atmosphere research.

This book gathers selected papers presented at the 8th International Congress on Environmental Geotechnics (ICEG), held on October 28 - November 1, 2018 in Hangzhou, China. The theme of the congress is "Towards a Sustainable Geoenvironment", which means meeting the needs of the present generation without compromising the ability of future generations to meet their own needs. Under this theme, the congress covers a broad range of topics and provides an excellent opportunity for academics, engineers, scientists, government officials, regulators, and planners to present, discuss and exchange notes on the latest advances and developments in the research and application of environmental geotechnics.

This book examines the meteorological phenomenon known as Western Disturbances (WDs) and traces their influence on the Indian subcontinent. It fully details the unique characteristics and dynamics of these disturbances, which produce large-scale instabilities in the atmosphere over northern India due to the orographic influence of the Himalayas. The authors first present a definition of the phenomenon and then go on to detail their structure and migration. Topics include dynamics, energetics and thermodynamics; modelling studies; land-use and land-cover interactions; and WDs in the changing climate. In addition, coverage outlines how WDs interact with and influence other weather systems throughout the four seasons of Indian climate: winter, pre-monsoon, monsoon and post-monsoon. It places special emphasis on wintertime dynamics since WDs significantly contribute to the precipitation in India during this time. The authors explain why this period should be termed "Indian winter monsoon" and differentiate it from the northeast monsoon which so far is the prevalent term used in the region's meteorological parlance. Complete with detailed illustrations and case studies, this monograph will help researchers and students gain a fundamental understanding of these important storms. This knowledge is essential not only for short-term and seasonal hydrometeorological forecasting but also for the assessment of regional climate change and its impacts.

The goals ofthe Symposium were to highlight advances in modelling ofatmosphere and ocean dynamics, to provide a forum where atmosphere and ocean scientists could present their latest research results and learn ofprogress and promising ideas in these allied disciplines; to facilitate interaction between theory and applications in atmosphere/ocean dynamics. These goals were seen to be especially important in view ofcurrent efforts to model climate requiring models which include interaction between atmosphere, ocean and land influences. Participants were delighted with the diversity ofthe scientific programme; the opportunity to meet fellow scientists from the other discipline (either atmosphere or ocean) with whom they do not normally interact through their own discipline; the opportunity to meet scientists from many countries other than their own; the opportunity to hear significant presentations (50 minutes) from the keynote speakers on a range ofrelevant topics. Certainly the goal ofcreating a forum for exchange between atmosphere and ocean scientists who need to input to create realistic models for climate prediction was achieved by the Symposium and this goal will hopefully be further advanced by the publication ofthese Proceedings.

Since the greenhouse effect emerged as a predictable threat, necessitating the evalu ation of its future impact on the environment in the various parts of the globe, interest in the climate changes during the Holocene has gained momentum. The background can be summarized by the sentence: The past is a key to the future. As a matter of fact, this sentence is in the opposite direction, on the dimension of time, to the principle adopted by the founders of the science of geology. They proposed that geological processes in the present should be used as a key for understanding the past. Another reason for the interest in the history of the climate of the Holocene can be described as the renaissance of a modified deterministic approach to the inter relation between physical and human geography. This relates in the first place to the fact that various investigations, especially as carried out by Hubert Lamb, showed that the sequence of climate changes previously suggested by Blytt and Sernander for Europe and adopted by most Holocene climatologists was far too general, and that there were more climate changes during recent history than previously taken account of. In the second place it was found out that these changes had had an impact on the history of human communities. Thus, one can conclude that once the taboo on geographical determinism (i. e."

The hydrological cycle of the Arctic Ocean has intimate and complex linkages to global climate: changes in one affect the other, usually with a feedback. The combined effects of large river runoff, advection of meteoric water, low evaporation rates and distillation by freezing contribute to the formation of a strong halocline in the upper Arctic ocean, which limits thermal communication between the sea ice and the warmer waters of Atlantic origin below. Sea ice and freshened surface waters are transported from the marginal seas by winds and currents, ultimately exiting the Arctic Ocean through Fram and Davis Straits. Variations in the freshwater outflow from these regions affect the density structure of the Arctic Ocean itself and so the surface heat balance. Another feedback is the effect these variations have on the density profile of the water column in the Greenland and Labrador seas where, at present, convection takes place mixing surface waters downwards with those at greater depth. This downward convective motion produces dense deep waters that flow outwards from these two centres and affect the entire North Atlantic.

This crucial volume arose out of the success of the first workshop of the Cyprus Institute held in 2005. The proceedings present an overview of the implications of climate change for the eastern Mediterranean and the impact of climate change response on regional economic activity, particularly in the hydrocarbon industry. This book is aimed not just at scientists and researchers but should command a much wider audience, including policy makers and politicians.

The feasibility to extract porous medium parameters from acoustic recordings is investigated. The thesis gives an excellent discussion of our basic understanding of different wave modes, using a full-waveform and multi-component approach. Focus lies on the dependency on porosity and permeability where especially the latter is difficult to estimate. In this thesis, this sensitivity is shown for interface-wave and reflected-wave modes. For each of the pseudo-Rayleigh and pseudo-Stoneley interface waves unique estimates for permeability and porosity can be obtained when impedance and attenuation are combined.
The pseudo-Stoneley wave is most sensitive to permeability: both the impedance and the attenuation are controlled by the fluid flow. Also from reflected-wave modes unique estimates for permeability and porosity can be obtained when the reflection coefficients of different reflected modes are combined. In this case the sensitivity to permeability is caused by subsurface heterogeneities generating mesoscopic fluid flow at seismic frequencies. The results of this thesis suggest that estimation of in-situ permeability is feasible, provided detection is carried out with multi-component measurements. The results of this thesis argely affect geotechnical and reservoir engineering practices.

This book provides the first comprehensive analysis of how aerosols form in the atmosphere through in situ processes as well as via transport from the surface (dust storms, seas spray, biogenic emissions, forest fires etc.). Such an analysis has been followed by the consideration of both observation data (various field observational experiments) and numerical modeling results to assess climate impacts of aerosols bearing in mind that these impacts are the most significant uncertainty in studying natural and anthropogenic causes of climate change.

Climate varies on all scales of time and space, bya large variety of reasons. However, before any discussion of reasons can be performed it is necessary to realize the very facts of climate variability by means of observations or reconstructions, respectively. In this book we focus on observed long-term trends of selected climate elements (tempera ture, precipitation, humidity, pressure ) as revealed by direct measurements of the Euro pean station network within the recent 100 years. Of course, there are a number of problems in detail: Reliability and accuracy of data, time series homogeneity, statistical confidence oftrends and so on. We hope that these problems are addressed in an instructive and, as far as possible, exhausting way. The main purpose of this work, however, was to provide a collection of trend charts which specify the regional particularities of observed climate trends in different months or seasons of the year leading us to an 'Atlas of observed climate trends in Europe'. Keeping in mind the recent World Meteorological Organization (WMO) climate nor mal (CLINO) period, we have also calculated the 1961-1990 trends."

Triggered by a discussion on the nature of future electricity supplies, wind - ergy utilisation has boomed dramatically, ?rst in the United States of America and Denmark and later in Germany and Spain.

ALEXANDER GILLESPIE & WILLIAM C.G. BURNS The idea for this book grew out of the Ecopolitics conference in Canberra, Australia in 1996. The conference captured the ferment of the climate change debate in the South Pacific, as well as some its potential implications for the region's inhabitants and e- systems. At that conference, one of the editors (Gillespie) delivered a paper on climate change issues in the region, as did Ros Taplin and Mark Diesendorf, who are also c- tributors to this volume. This book focuses on climate change issues in Australia, New Zealand, and the small island nations in the Pacific as the world struggles to cope with possible the impacts of environmental change and to formulate effective responses. While Australia and New Zealand's per capita emissions of greenhouse gases are among the highest in the world, their aggregate contributions are small. However, both nations may exert a disprop- tionate influence in the global greenhouse debate because their obstinate positions at recent conferences of the parties to the United Nations Framework Convention on C- mate Change (FCCC) may provide justification for other developed nations, as well as developing countries, to refuse to make meaningful reductions in their greenhouse gas emissions.
