Significant advancements in the experimental analysis of soils
and shales have been achieved during the last few decades.
Outstanding progress in the field has led to the theoretical
development of geomechanical theories and important engineering
applications.
This book provides the reader with an overview of recent
advances in a variety of advanced experimental techniques and
results for the analysis of the behaviour of geomaterials under
multiphysical testing conditions. Modern trends in experimental
geomechanics for soils and shales are discussed, including testing
materials in variably saturated conditions, non-isothermal
experiments, micro-scale investigations and image analysis
techniques. Six theme papers from leading researchers in
experimental geomechanics are also included.
This book is intended for postgraduate students, researchers and
practitioners in fields where multiphysical testing of soils and
shales plays a fundamental role, such as unsaturated soil and rock
mechanics, petroleum engineering, nuclear waste storage
engineering, unconventional energy resources and CO2 geological
sequestration.
This book contains the most recent progress in data assimilation in
meteorology, oceanography and hydrology including land surface. It
spans both theoretical and applicative aspects with various
methodologies such as variational, Kalman filter, ensemble, Monte
Carlo and artificial intelligence methods. Besides data
assimilation, other important topics are also covered including
targeting observation, sensitivity analysis, and parameter
estimation. The book will be useful to individual researchers as
well as graduate students for a reference in the field of data
assimilation.
The studies in this dissertation aim at advancing our scientific
understandings about physical processes involved in the
aerosol-cloud-precipitation interaction and quantitatively
assessing the impacts of aerosols on the cloud systems with diverse
scales over the globe on the basis of the observational data
analysis and various modeling studies. As recognized in the Fifth
Assessment Report by the Inter-government Panel on Climate Change,
the magnitude of radiative forcing by atmospheric aerosols is
highly uncertain, representing the largest uncertainty in
projections of future climate by anthropogenic activities. By using
a newly implemented cloud microphysical scheme in the
cloud-resolving model, the thesis assesses aerosol-cloud
interaction for distinct weather systems, ranging from individual
cumulus to mesoscale convective systems. This thesis also
introduces a novel hierarchical modeling approach that solves a
long outstanding mismatch between simulations by regional weather
models and global climate models in the climate modeling community.
More importantly, the thesis provides key scientific solutions to
several challenging questions in climate science, including the
global impacts of the Asian pollution. As scientists wrestle with
the complexities of climate change in response to varied
anthropogenic forcing, perhaps no problem is more challenging than
the understanding of the impacts of atmospheric aerosols from air
pollution on clouds and the global circulation.
Climate change is a major challenge facing the modern world. The
chemistry of air and it's influence on the climate system forms the
main focus of this monograph. The book presents a problem-based
approach to presenting global atmospheric processes, evaluating the
effects of changing air composition as well as possibilities for
interference within these processes and indicates ways for solving
the problem of climate change through chemistry. The new edition
includes innovations and latest research results.
The focus of this work is the development of models to estimate
evapotranspiration (ET), investigating the partitioning between
soil evaporation and plant transpiration at field and regional
scales, and calculating ET over heterogeneous vegetated surfaces.
Different algorithms with varying complexities as well as spatial
and temporal resolutions are developed to estimate
evapotranspiration from different data inputs. The author proposes
a novel approach to estimate ET from remote sensing by exploiting
the linkage between water and carbon cycles. At the field scale, a
hybrid dual source model (H-D model) is proposed. It is verified
with field observations over four different ecosystems and coupled
with a soil water and heat transfer model, to simulate water and
heat transfer in the soil-plant-atmosphere continuum. At the
regional scale, a hybrid dual source scheme and trapezoid framework
based ET model (HTEM), using remote sensing images is developed.
This model is verified with data from the USA and China and the
impact of agricultural water-saving on ET of different land use
types is analyzed, in these chapters. The author discusses the
potential of using a remote sensing ET model in the real management
of water resources in a large irrigation district. This work would
be of particular interest to any hydrologist or micro-meteorologist
who works on ET estimation and it will also appeal to the ecologist
who works on the coupled water and carbon cycles. Land
evapotranspiration is an important research topic in hydrology,
meteorology, ecology and agricultural sciences. Dr. Yuting Yang
works at the CSIRO Land and Water, Canberra, Australia.
This volume enables readers to understand the complexity
associated with climate change policy and the science behind it.
For example, the author describes the criticism and defense of the
widely known hockey stick temperature graph derived from combining
instrumental data and proxy temperature indications using tree
ring, ice core and other paleoclimatic data.
Readers will also learn that global warming cannot easily be
avoided by reducing CO2 and other greenhouse gas emissions in rich
countries. Not only is emissions reduction extremely difficult in
rich countries, but demands such as the UN mandate to improve the
lives of the poorest global citizens cannot be satisfied without
significantly increasing global energy use, and CO2 emissions.
Therefore, the author asserts that climate engineering and
adaptation are preferable to mitigation, particularly since the
science is less than adequate for making firm statements about the
Earth s future climate.Readers will also learn that global warming

Understanding the balance of society and nature is imperative when
researching ecosystems and their global influence. A method of
studying the health of these ecosystems is biodiversity. The more
diverse the species that live in an ecosystem, the healthier it is.
As the climate continues to transform, small-scale ecosystems are
affected, altering their diversity. Environmentalists need a book
of research that studies the specific impacts of climate change and
how it affects the future of the environment. Current State and
Future Impacts of Climate Change on Biodiversity is a pivotal
reference source that provides vital research on biological systems
and how climate change influences their health. While highlighting
topics such as genetic diversity, economic valuation, and climatic
conditions, this publication explores the effects of climate change
as well as the methods of sustainable management within ecosystems.
This book is ideally designed for environmental scientists,
environmental professionals, scientists, ecologists,
conservationists, government officials, policymakers,
agriculturalists, environmentalists, zoologists, botanists,
entomologists, urban planners, researchers, scholars, and students
seeking research on current and future developments of various
ecosystems.
This thesis focuses on the seismic response of piles in liquefiable
ground. It describes the design of a three-dimensional, unified
plasticity model for large post-liquefaction shear deformation of
sand, formulated and implemented for parallel computing. It also
presents a three-dimensional, dynamic finite element analysis
method for piles in liquefiable ground, developed on the basis of
this model,. Employing a combination of case analysis, centrifuge
shaking table experiments and numerical simulations using the
proposed methods, it demonstrates the seismic response patterns of
single piles in liquefiable ground. These include basic
force-resistance mode, kinematic and inertial interaction coupling
mechanism and major influence factors. It also discusses a beam on
the nonlinear Winkler foundation (BNWF) solution and a modified
neutral plane solution developed and validated using centrifuge
experiments for piles in consolidating and reconsolidating ground.
Lastly, it studies axial pile force and settlement during
post-earthquake reconsolidation, showing pile axial force to be
irrelevant in the reconsolidation process, while settlement is
process dependent.
This book provides a collection of the state-of-the-art
methodologies and approaches suggested for detecting extremes,
trend analysis, accounting for nonstationarities, and uncertainties
associated with extreme value analysis in a changing climate. This
volume is designed so that it can be used as the primary reference
on the available methodologies for analysis of climate extremes.
Furthermore, the book addresses current hydrometeorologic global
data sets and their applications for global scale analysis of
extremes. While the main objective is to deliver recent theoretical
concepts, several case studies on extreme climate conditions are
provided. Audience The book is suitable for teaching in graduate
courses in the disciplines of Civil and Environmental Engineering,
Earth System Science, Meteorology and Atmospheric Sciences.
General circulation models (GCMs), which define the fundamental
dynamics of atmospheric circulation, are nowadays used in various
fields of atmospheric science such as weather forecasting, climate
predictions and environmental estimations. The Second Edition of
this renowned work has been updated to include recent progress of
high resolution global modeling. It also contains for the first
time aspects of high-resolution global non-hydrostatic models that
the author has been studying since the publication of the first
edition. Some highlighted results from the Non-hydrostatic
ICosahedral Atmospheric Model (NICAM) are also included. The author
outlines the theoretical concepts, simple models and numerical
methods for modeling the general circulation of the atmosphere.
Concentrating on the physical mechanisms responsible for the
development of large-scale circulation of the atmosphere, the book
offers comprehensive coverage of an important and rapidly
developing technique used in the atmospheric science. Dynamic
interpretations of the atmospheric structure and their aspects in
the general circulation model are described step by step.
The book examines surface rainfall processes through
cloud-resolving modeling and quantitative analysis of surface
rainfall budget and summarizes modeling and analysis results in
recent seven years. The book shows validation of precipitation
modeling against observations and derives a set of diagnostic
precipitation equations. The book provides detailed discussions of
the applications of precipitation equations to the examination of
effects of sea surface temperature, vertical wind shear, radiation,
and ice clouds on torrential rainfall processes in the tropics and
mid-latitudes, and to the studies of sensitivity of precipitation
modeling to uncertainty of the initial conditions and to the
estimate of precipitation efficiency. The book can be used as a
text book for graduate students and will be beneficial to
researchers and forecasters for precipitation process studies and
operational forecasts.
The climate of the Earth is always changing. As the debate over the
implications of changes in the Earth's climate has grown, the term
climate change has come to refer primarily to changes we've seen
over recent years and those which are predicted to be coming,
mainly as a result of human behavior. This book serves as a broad,
accessible guide to the science behind this often political and
heated debate by providing scientific detail and evidence in
language that is clear to both the non-specialist and the serious
student.

A thorough overview of the phenomenon of flooding, including
frequency, damage, and information about organizations that help
flood victims. What causes killer floods? Why are they so
destructive? Can they be predicted, tamed, or eliminated? Find the
answers in Natural Disasters: Floods, which discusses where and how
often floods occur in the United States, how the federal government
handles flood control, and the extent of the economic and social
damage caused by floods.
Why did T-Rex become extinct? Why did the Mayan civilization
disappear? If the ancient Israelis did indeed cross the Red Sea, as
reported in the Bible, what weather phenomena might have produced
the parting of the waters? Why was nearly all human life swept away
73,000 years ago? And what factors created the Great American
Dustbowl of the 1930s?
The extraordinary people who are interested in asking--and
answering--such questions are known as climatologists. In a lively
narrative full of intriguing facts, award-winning, internationally
known climatologist Randy Cerveny takes the reader on a fascinating
tour of some of the world's most perplexing and provocative climate
mysteries, past and present. Cerveny explains the science of
climate study--from digging ice cores in Antarctica to counting
tree rings in Arizona--and the various specialists whose ingenious
techniques help to sort out climate's intricate components. He also
delves into the human impact of weather through fictional
introductions to each chapter that depict how climate change might
have affected a typical inhabitant of the ancient Sahara or Indus
Valley, a peasant during Europe's "Little Ice Age," or an aviation
expert probing a deadly jet crash in New York City. Finally, he
discusses research that attempts to forecast the weather of the
next 10,000 years--essential information for planning the nuclear
waste depository at Yucca Mountain, Nevada.
For readers of An Inconvenient Truth, devotees of the Weather
Channel, history buffs, popular science fans, or anyone who wonders
what makes our weather tick--and how it will impact our future,
this engaging book offers much to ponder and to enjoy.
This is the first book dedicated to the developing knowledge on how
the world's largest ice sheet formed and changed over its 34
million years history. In explaining the story of Antartica,
information on terrestrial and marine geology, sedimentology,
glacier geophysics (including airborne reconnaissance), shipborne
geophysics, and numerical ice sheet and climate modelling, will be
interwoven within eleven chapters, each deling with an important
historical theme. The approach will be to first 'set the scene',
involving chapters dedicated to how ice sheets and their glacial
history can be measured. This opening section will provide
information necessary to comprehend the latter section of the book,
in which five chapters will related the glacial and climate
evolution of Antartica during the most important time-frames in
which changes have occurred.

Global Change studies are increasingly being considered a vital
source of information to understand the Earth Environment, in
particular in the framework of human-induced climate change and
land use transformation. Satellite Earth Observing systems provide
a unique tool to monitor those changes. While the range of
applications and innovative techniques is constantly increasing,
this book provides a summary of key case studies where satellite
data offer critical information to understand the causes and
effects of those environmental changes, minimizing their negative
impacts. This book will be of interest to researchers and
practitioners in the field of remote sensing, geographical
information, meteorology and environmental sciences. Also
scientists and graduate up to post-graduate level students in
environmental science will find valuable information in this book.
Climate and other environmental changes are drawing unprecedented
concern and attention from national governments, international
organizations and local communities. Global warming has left
noticeable impacts on the environment and the ecosystems it
supports (including humans), and has important implications for
sustainable economic and social development in the future.
Satellite observations of climate and environmental change have
become an increasingly important tool in recent years in helping to
shape the response of international communities to this critical
global challenge. The book presents the latest advances in
satellite-based remote sensing of the Earth's environment - ranging
from applications in climate and atmospheric science to hydrology,
oceanography, hydrology, geomorphology, ecology and fire studies.
Introductory chapters also cover key technical aspects such as
instrumentation, calibration, data analysis, and GIS tools for
decision-making.
In 1998, my colleague, Forrest Mims, and I began a project to
develop inexpensive handheld atmosphere monitoring instruments for
the GLOBE Program, an international environmental science and
education program that began its operations on Earth Day, 1995.
GLOBE's goal was to involve students, teachers, and scientists
around the world in authentic partn- ships in which scientists
would develop instrumentation and experimental protocols suitable
for student use. In return, data collected by students and their
teachers would be used by scientists in their research. This kind
of collaboration represented a grand vision for science education
which had never before been attempted on such a scale, and we
embraced this vision with great enthusiasm. Between 1998 and 2006,
Forrest Mims and I collaborated on the development of several
instruments based on Mims' original concept of using light emitting
diodes as spectrally selective detectors of sunlight, which was
first published in the peer-reviewed literature in 1992. These
instruments have evolved into a set of tools and procedures for
monitoring the transmission of sunlight through the atmosphere, and
they can be used to learn a great deal about the composition of the
atmosphere and the dynamics of the Earth/atmosphere/sun system. If
measurements with these instruments are made properly, they have
significant scientific value, as well.
