Weather: Spaces, Mobilities and Affects (Hardcover): Kaya Barry, Maria Borovnik, Tim Edensor Weather: Spaces, Mobilities and Affects (Hardcover)
Kaya Barry, Maria Borovnik, Tim Edensor
R4,505 Discovery Miles 45 050 Ships in 10 - 15 working days

This book delves into the everyday spaces, diverse mobilities and affective potency of weather. It presents cutting-edge research into the multiplicity of weather phenomena and analyses the lived experiences of humans in conjunction with contemporary issues, notably climate change. The book considers how everyday experiences of weather in the mundane lives of people are linked to broader changes in weather patterns and climate change. Heat, dust, ice, snow, precipitation, sunlight, clouds, tides and fog are states of weather that impact on the ways in which humans become intertwined with landscapes. Our experiences with weather are diverse and ever-changing, and engaging with weather entangles humans with mobilities, materials and landscapes. This book thus explores affective and sensory resonances, drawing upon a variety of theoretical, empirical and creative material to investigate how weather is perceived in different social and cultural contexts. Key themes focus on the mobilities generated by weather, the affective and sensual potency of weather, and the diverse cultural forms and practices that exemplify how weather is historically, geographically and artistically represented. Offering a social and cultural understanding of weather events, this book contributes to a growing literature on weather across various disciplines, including human geography and cultural geography, and will thus appeal to students and scholars of geography, sociology, humanities, cultural studies and the arts.

Jacques C.J. Nihoul, Peter O. Zavialov, Philip P. Micklin
R5,353 Discovery Miles 53 530 Ships in 18 - 22 working days

There are incentive indications that the growth of human population, the increasing use and abuse of natural resources combined with climate changes (probably due to anthropic pollution, to some extent) exert a considerable stress on closed (or semi-enclosed) seas and lakes. In many regions of the world, marine and lacustrine hydrosystems are (or have been) the object of severe or fatal alterations, from changes in regional hydrological regimes and/or modifications of the quantity or the quality of water resources associated with (natural or man-made) land reclamation, deterioration of geochemical balances (increased salinity, oxygen's depletion .. . ), mutations of ecosystems (eutrophication, dramatic decrease in biological diversity ... ) to geological disturbances and to the socio-economic perturbations which have been - or may be in the near future - the consequences of them. Seas and lakes are dying all over the world and some may be regarded as already dead and there is an urgent need to try to understand how this is happening and identify the causes of the observed mutations, weighing the relative effects of climatic evolution and anthropic interferences. This book is the outcome of the NATO Advanced Research Workshop, held in Liege in May 2003. The Workshop was organized at th the University of Liege as a follow on meeting to the 35 International Liege Colloquium on Ocean Dynamics, dedicated in 2003 to Dying and Dead Seas. The book contains the synthesis of the lectures given by 16 main speakers during the ARW.

Inverse Methods in Physical Oceanography (Hardcover, New): Andrew F Bennett Inverse Methods in Physical Oceanography (Hardcover, New)
Andrew F Bennett
R4,318 R3,636 Discovery Miles 36 360 Save R682 (16%) Ships in 10 - 15 working days

Professor Bennett's work explores the potential for inverse theory, emphasizing possibilities rather than expedient or rudimentary applications. In addition to interpolating the data and adding realism to the model solutions, the methods can yield estimates for unobserved flow variables, forcing fields, and model parameters. Inverse formulations can resolve ill-posed modeling problems, lead to design criteria for oceanic observing systems, and enable the testing of models as scientific hypothesis. Ocean models considered range from linear, finite-dimensional systems of equality and inequality constraints, to nonlinear, regional primitive-equation models. Examples from the recent oceanographic literature are analyzed, and several outstanding research problems are surveyed. The methods employ solution techniques including Kalman filters and smoothers, representer expansions and descent algorithms. Exercises of varying difficulty rehearse technical skills and supplement the central theoretical development.

Frontiers in Geographical Teaching (Paperback): Richard J. Chorley, Peter Haggett Frontiers in Geographical Teaching (Paperback)
Richard J. Chorley, Peter Haggett
R1,179 Discovery Miles 11 790 Ships in 10 - 15 working days

Originally published in 1965 and with a second edition in 1970. Building upon the original two Madingley Hall seminars for teachers of non-university geography in 1965, this book presents an updated research picture of the 1970 transatlantic perspective. Answering the questions "What is happening in geography" and "What impact does this have on school geography", this provided a real link for students who were then making the increasingly difficult transition from school to university geography. Originally receiving a hostile reaction from British journals, the book's diagnosis and prognosis were a forerunner of developments in methodological changes of the discipline. This work collects a series of essays delineating geographic concepts in terms of the philosophic underpinnings, assessment of the geomorphic system, climatology, and social economic and historical changing trends. Techniques are reviewed including quantitative methods for geomorphology and social geography, fieldwork both in urban areas and land-use surveys, and finally in physical planning. Final analyses examine and contrast the teaching methods and courses in American and British High Schools, Colleges and Universities.

Directions in Geography (Paperback): Richard J. Chorley Directions in Geography (Paperback)
Richard J. Chorley
R1,171 Discovery Miles 11 710 Ships in 10 - 15 working days

Originally published in 1973. This collection of essays looks at the 'quantitative revolution' and the 'new geography' by some of the geographers who had a significant part in those innovations and looks ahead to further developments. The views in the chapters are diverse and offer a fascinating glimpse of the discipline of geography as the subject was undergoing such change and becoming more socially committed. They cover theory, spatial-systems theory, forecasting, human ecology and climatology alongside the teaching of the subject. The concerns of the contemporary geographer come across and are of interest today as these areas have developed still more.

R3,132 Discovery Miles 31 320 Ships in 18 - 22 working days

This book presents recent results of collaborative studies in geophysics and ecology, focusing on the relationship between the physical environment and the distribution of the marine coastal ecosystems. The study area, the Sakiyamawan-Amitoriwan nature conservation area in Iriomote Island of Japan, is the only oceanic nature conservation area in the country. The area has no access roads, and the bay perimeter is uninhabited; therefore, it preserves the natural environment with very little human impact. In addition, it has various environmental gradients such as topography and inflows from rivers with mangrove forests which affect the distribution of marine coastal ecosystems such as those containing reef-building corals, sea grasses, and hermit crabs. For these reasons, the area is one of the best places for the study of the relationship between the physical environment and the distribution of the marine coastal ecosystems, a relationship that is important for their conservation but has not been investigated fully. This book is aimed at students and researchers in the fields of oceanography and marine coastal ecology as well as general readers who are interested in coral reefs, diving, and nature conservation.

R5,356 Discovery Miles 53 560 Ships in 18 - 22 working days

The two-way oceanic exchanges that connect the Arctic and Atlantic oceans through subarctic seas are of fundamental importance to climate. Change may certainly be imposed on the Arctic Ocean from subarctic seas, including a changing poleward ocean heat flux that is central to determining the present state and future fate of the perennial sea-ice. And the signal of Arctic change is expected to have its major climatic impact by reaching south through subarctic seas, either side of Greenland, to modulate the Atlantic thermohaline a ~conveyora (TM). Developing the predictive skills of climate models is seen to be the most direct way of extending the ability of society to mitigate for or adapt to 'global change' and is the main justification for continuing an intense observational effort in these waters. As records have lengthened, they have shown that important aspects of oceanic exchange through subarctic seas are currently at a long-term extreme state, providing further motivation for their study. As one important example, the longest records of all show that the temperature of the main oceanic inflow to the Norwegian Sea along the Scottish shelf and slope, and the temperature of the poleward extension of that flow through the Kola Section of the Barents Sea have never been greater in >100 years. However, we are only now beginning to understand the climatic impact of the remarkable events that are currently in train in subarctic waters, and models remain undecided on some of the most basic issues that link change in our northern seas to climate. Reviewing the achievements of an intense recent observing and modelling effort, this volume intends to assemble the body of evidence thatclimate models will need if they are one day to make that assessment, quantifying the ocean exchanges through subarctic seas, describing their importance to climate as we currently understand it, explaining their variability, setting out our current ideas on the forcing of these fluxes and our improved capability in modelling the fluxes themselves and the processes at work. Much of that evidence is assembled here for the first time.

R3,619 R3,359 Discovery Miles 33 590 Save R260 (7%) Ships in 10 - 15 working days

The book focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure. Upscaled models are developed and it is shown that the presence of material heterogeneities may give rise to additional non-equilibrium terms in the governing equations or to hysteresis in the averaged constitutive relationships.
