This volume is a collection of lectures given at the two colloquia on atmospheric flows over complex terrain with applications to wind energy and air pollution, organized and sponsored by ICTP in Trieste, Italy. The colloquia were the result of the recognition of the importance of renewable energy sources, an important aspect which grows yearly as the environmental problems become more pronounced and their effects more direct and intense, while at the same time, the wise management of the Earth's evidently limited resources becomes imperative.It is divided into two main parts. The first, which comprises Chaps. 1 to 4, presents the structure of the atmospheric boundary layer with emphasis in the region adjacent to the ground. The second, Chaps. 5 to 10, discusses methods for the numerical computation of the wind field on an arbitrary terrain. The unique feature of this book is that it does not stop at the theoretical exposition of the analytical and numerical techniques but includes a number of codes, in a diskette, where the mechanisms and techniques presented in the main part are implemented and can be run by the reader. Some of the codes are of instructional value while others can be utilized for simple operational work.Some of the lecturers are: D N Asimakopoulos, C I Aspliden, V R Barros, A K Blackadar, G A Dalu, A de Baas, D Etling, G Furlan, D P Lalas, P J Mason, C F Ratto and F B Smith.

"The Atlas of Climate Change-Based on SEAP-CMIP5" is intended to satisfy readers' curiosity: how will our climate system change over the next 100 years? It is the first showcase for the state-of -the-art earth system models that released their CMIP5 simulations for the IPCC AR5.The atlas focuses on both the past climate system change from 1850 and the projection of the future climate system change to 2100 using the RCP2.6, RCP4.5 and RCP8.5 scenarios based on climate models. This provides the research and application community interested in the impact of climate change on fields such as agriculture, ecosystem, environment,water resources, energy, health, economy, risk governance and international negotiation, etc. with the newest climate change projection information. Additionally, the atlas will show the historical responsibility of the developed/developing countries and possible contributions to the mitigation of climate change according to their pledge of GHG emission reduction after the Cancun Agreement as an extension numerical experiment to CMIP5 with NCAR's CESM1.0. The authors will update this atlas after future releases of CMIP5 model outputs and update the figures in the second edition of the atlas in 2012-2013. Both Prof. Wenjie Dong and Yan Guo work at the Beijing Normal University, China. Prof. Fumin Ren works at the China Meteorological Administration, China. Prof. Jianbin Huang works at the Tsinghua University, China.

Stratospheric processes play a signi?cant role in regulating the weather and c- mate of the Earth system. Solar radiation, which is the primary source of energy for the tropospheric weather systems, is absorbed by ozone when it passes through the stratosphere, thereby modulating the solar-forcing energy reaching into the t- posphere. The concentrations of the radiatively sensitive greenhouse gases present in the lower atmosphere, such as water vapor, carbon dioxide, and ozone, control the radiation balance of the atmosphere by the two-way interaction between the stratosphere and troposphere. The stratosphere is the transition region which interacts with the weather s- tems in the lower atmosphere and the richly ionized upper atmosphere. Therefore, this part of the atmosphere provides a long list of challenging scienti?c problems of basic nature involving its thermal structure, energetics, composition, dynamics, chemistry, and modeling. The lower stratosphere is very much linked dynamically, radiatively, and chemically with the upper troposphere, even though the temperature characteristics of these regions are different. The stratosphere is a region of high stability, rich in ozone and poor in water - por and temperature increases with altitude. The lower stratospheric ozone absorbs the harmful ultraviolet (UV) radiation from the sun and protects life on the Earth. On the other hand, the troposphere has high concentrations of water vapor, is low in ozone, and temperature decreases with altitude. The convective activity is more in the troposphere than in the stratospher

Interest in volatile organic compounds (VOCs) as air pollutants has increased dramatically in recent years. This book covers a number of very topical issues concerning VOCs, including stratospheric ozone depletion due to CFCs, and the properties of alternative substances; the role of VOCs in the photochemical formation of lower atmosphere (tropospheric) ozone; and the problem of the direct toxicity of VOCs such as benzene and formaldehyde. This Issue reviews our current knowledge of VOCs, drawing upon the expertise of renowned experts and major national and international research programmes. It examines man-made and natural sources, as well as pathways and chemical reactions in the atmosphere. It also looks closely at the sources and concentrations of VOCs indoors, where humans are most likely to be exposed to them. Volatile Organic Compounds in the Atmosphere describes techniques used for the calculation of emissions inventories and strategies for control, and explores the many Government policy matters relating to VOCs. It provides readers with in-depth, clearly explained coverage of the many complex scientific and policy issues surrounding VOCs in the atmosphere.

Mountains are water towers of our world, but their role in global water resources may be altered due to changing climate. This book provides an integrated assessment of the spatial and temporal variability of both recent and future climate change impacts in the Yellow River source region (YRSR) with specific focus on extremes. The book is structured across four different topics from detecting contemporary hydro-climatic changes, comparing three different statistical downscaling methods, assessing elevation dependency of expected changes in temperature, and projecting future climate-induced hydrologic changes in the YRSR. The detection of historical hydro-climatic changes in recent decades indicates that climate change may already be happening and may pose a serious threat to water availability in this region. However, an ensemble of climate change projections for the periods 2046-2065 and 2081-2100 based on two GCMs and three emission scenarios demonstrates that the future water availability of this region would increase due to climate change. This discrepancy suggests that contemporary hydro-climatic experience based on past records alone may not always provide a reliable guide to the future. This study makes an important contribution toward an improved understanding of climate change impacts in the YRSR. The knowledge generated has major implications for water resources management in the Yellow River and will be instructive for climate change impacts studies in other mountain areas.

Volumes I and II offer a comprehensive discussion that together will serve as an important resource for practitioners, professionals, and students alike.

Temperature and precipitation increase and decrease because of natural causes. However, anthropogenic changes, such as an enhanced greenhouse effect, may result in alterations in the regional climate and in relative sea level. Serious changes in climate and sea level-with adverse effects particularly along low-lying coasts-would affect millions of people. Climate Change takes an in-depth, worldwide look at coastal habitation with respect to these natural and anthropogenic changes.
No universally applicable coastal model can be used to describe climatic changes. This unique book provides individual discussions of beaches and barrier islands, cliffs, deltas, tidal flats and wetlands, reefs, and atolls. The impact of climatic change on coastal ecology and agriculture is investigated, and human responses to the effects of climatic change along the world's coasts are included.

In order to understand how climate may vary in the future - whether as a result of human activities or of natural fluctuations - we must first understand how and why it has varied in the past. "Climate Since AD 1500" presents a new perspective on the "Little Ice Age" and of the climate of the 20th century. The editors have gathered together over 50 contributors from all over the world to provide as wide a geographical dimension as possible. Leading scientists in their fields, they present climate and meteorological records of climatic variations available for the last 500 years, including research from several areas not previously recorded in an English language volume. These records include: historical documents; long instrumental records; tree rings and ice core records; records based on worldwide current research. Factors that are potentially important in causing climatic changes are also discussed. A postscript has been added since the previous edition to incorporate new research from the vast range of literature published on the subject in the last two years.

This book introduces systematically the application of Bayesian probabilistic approach in soil mechanics and geotechnical engineering. Four typical problems are analyzed by using Bayesian probabilistic approach, i.e., to model the effect of initial void ratio on the soil-water characteristic curve (SWCC) of unsaturated soil, to select the optimal model for the prediction of the creep behavior of soft soil under one-dimensional straining, to identify model parameters of soils and to select constitutive model of soils considering critical state concept. This book selects the simple and easy-to-understand Bayesian probabilistic algorithm, so that readers can master the Bayesian method to analyze and solve the problem in a short time. In addition, this book provides MATLAB codes for various algorithms and source codes for constitutive models so that readers can directly analyze and practice. This book is useful as a postgraduate textbook for civil engineering, hydraulic engineering, transportation, railway, engineering geology and other majors in colleges and universities, and as an elective course for senior undergraduates. It is also useful as a reference for relevant professional scientific researchers and engineers.

A gripping description of New England's storm of the century.

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 book concerns the theoretical foundations of hydro mechanics of Pelton turbines from a viewpoint of engineering. For reference purposes all relevant flow processes and hydraulic aspects in a Pelton turbine have been analyzed completely and systematically. The analyses especially include the quantification of all possible losses existing in the Pelton turbine and the indication of most available potential for further enhancing the system efficiency. As a guideline the book therefore supports further developments of Pelton turbines with regard to their hydraulic designs and optimizations. It is thus suitable for the development and design engineers as well as those working in the field of turbo machinery. Many laws described in the book can also be directly used to simplify aspects of computational fluid dynamics (CFD) or to develop new computational methods. The well-executed examples help better understanding the related flow mechanics.

Your Guide to Watching Clouds and Understanding the Weather From the soothing sound of rain to the shrill whistle of a blizzard, from the house-shaking rumble of thunder to the violent fury of a hurricane, weather is a fascinating part of our lives. We watch it. We listen to it. We feel it. We try to predict it. But how well do we truly understand it? Professional meteorologist Ryan Henning presents Field Guide to the Weather, a handy reference to meteorology and to the types of weather phenomena that one might encounter at home or in nature. It includes a simple introduction to the basics of meteorology-explaining the aspects of the atmosphere that dictate how weather works. From there, the field guide looks at a variety of individual weather topics: cloud formation (and cloud-type identification), various forms of precipitation, and much more. The author goes on to discuss government-issued watches and warnings, and weather safety. Plus, readers are sure to appreciate the book's helpful guide to interpreting weather forecasts and available model information when planning an afternoon picnic or next week's vacation. Field Guide to the Weather is a perfect introduction to the science of weather. The information is captivating for kids and adults alike. The simple explanations are useful in easing the mind of a frightened child, and the in-depth details help adults learn to understand and prepare for the weather ahead.

Climate may be defined as the synthesis of long-term atmospheric conditions characteristic of a particular place. Consequently, the study of climate relies on sustained records of daily values. However, both location and equipment are variables and precise measurements may not be possible. There are occasions when an estimate rather than a measurement is necessary, as when gauging the unrecorded past or future. The value of applied climatology - the study of the impact of climate - lies in the analysis of measurements and estimates within the context of change. This study provides a review of the theory and practice underlying current climatic research. The author describes the nature of atmospheric resources - solar energy, wind power and water supply - and describes the specification and treatment of climate data.

The Medieval Warm Period and the Little Ice Age are widely considered to have been the major features of the Earth's climate over the past 1000 years. In this volume the issue of whether there really was a Medieval Warm Period, and if so, where and when, is addressed. The types of evidence examined include historical documents, tree rings, ice cores, glacial-geological records, borehole temperatures, paleoecological data and records of solar receipts inferred from cosmogenic isotopes. Growth in the availability of several of these types of data in recent years, and technical advances in their derivation and use, warrant this state-of-the-art re-examination of the Medieval Warm Period. The book will be of value to all those with an interest in the natural variability of the climate system, for example those concerned with anticipating and detecting human-produced climate change.

The new series, Advances in Bioclimatology provides authorative reviews on the latest developments in all research areas concerned with the effects of climatic factors on living organisms - be they plants, animals or humans.

The following topics are covered in the first volume: - Deforestation, revegetation, water balance and climate; - Interaction of CO2 with growth limiting environmental factors in vegetation productivity; - Radiative transfer in nonhomogenous plant canopies; - Techniques to measure CO2 flux densities from surface and airborne sensors. Future volumes will include reviews of frost, its occurrence, impact and prevention (Vol. 2); laser remote sensing of vegetation; global monitoring of forests with radar; human melanoma and ultraviolet radiation; maintaining health of farm animals under adverse conditions.

A hydroinformatics system represents an electronic knowledge encapsulator that models part of the real world and can be used for the simulation and analysis of physical, chemical and biological processes in water systems, in order to achieve a better management of the aquatic environment. Thus, modelling is at the heart of hydroinformatics. The theory of nonlinear dynamics and chaos, and the extent to which recent improvements in the understanding of inherently nonlinear natural processes present challenges to the use of mathematical models in the analysis of water and environmental systems, are elaborated in this work. In particular, it demonstrates that the deterministic chaos present in many nonlinear systems can impose fundamental limitations on our ability to predict behaviour, even when well-defined mathematical models exist. On the other hand, methodologies and tools from the theory of nonlinear dynamics and chaos can provide means for a better accuracy of short-term predictions as demonstrated through the practical applications in this work.
