Dynamics of the Upper Atmosphere


Book Description




Space Physics and Aeronomy, Upper Atmosphere Dynamics and Energetics


Book Description

A comprehensive overview of the structure and variability of the upper atmosphere Earth's upper atmosphere is an open system that is strongly influenced by energy and momentum inputs from both above and below. New observation and modeing techniques have provided insights into dynamics, energetics, and chemical processes in the upper atmosphere. Upper Atmosphere Dynamics and Energetics presents an overview of key research advances in upper atmospheric physics, and measurement and modeling techniques, along with remaining challenges for understanding the state and variability of the upper atmospheric system. Volume highlights include: Insights into the interconnections between different areas of upper atmospheric science Appreciation of the dynamics and complexity of the global upper atmospheric system Techniques for observing and measuring the upper atmosphere Responses of the upper atmosphere to external drivers The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Annals of the International Geophysical Year


Book Description

Annals of the International Geophysical Year, Volume 48: Bibliography and Index contains bibliography of articles published in connection with the International Geophysical Year (IGY). The preparatory and operational phases of the IGY occupied nearly a decade and the data accumulated in the many scientific disciplines by workers in some 67 countries will provide material for publication for many years. The references have been assembled from information supplied by a wide variety of sources. These references have been grouped into 21 sections, of which Sections I-XIV followed the discipline grouping adopted during the IGY. Within each section references have been arranged in alphabetical order according to the name of the principal author. Anonymous articles are listed at the end of each section, again arranged in alphabetical order by title. In the scientific literature, author's names originally printed in Cyrillic symbols sometimes appear with several different spellings because of the use of different transliteration systems. In the present Bibliography an attempt has been made to achieve consistency by using the same transliteration system throughout. This book will prove useful to geophysicists and researchers who are interested in the accomplishments of the International Geophysical Year.




The Earth's Atmosphere


Book Description

The author has sought to incorporate in the book some of the fundamental concepts and principles of the physics and dynamics of the atmosphere, a knowledge and understanding of which should help an average student of science to comprehend some of the great complexities of the earth-atmosphere system, in which a thr- way interaction between the atmosphere, the land and the ocean tends to maintain an overall mass and energy balance in the system through physical and dynamical processes. The book, divided into two parts and consisting of 19 chapters, introduces only those aspects of the subject that, according to the author, are deemed essential to meet the objective in view. The emphasis is more on clarity and understanding of physical and dynamical principles than on details of complex theories and ma- ematics. Attempt is made to treat each subject from ?rst principles and trace its development to present state, as far as possible. However, a knowledge of basic c- culus and differential equations is sine qua non especially for some of the chapters which appear later in the book.




The Upper Atmosphere


Book Description

Especially due to the increasing environmental problems there is a need to collect as many data as possible in the upper atmosphere. This book serves as a general multidisciplinary guide and introduction for a more effective use of the large amount of now available data from the Earth's atmosphere. It also shows the problems of the use of large amounts of time series data - for basic science as well as for environmental monitoring - and the related information systems. The book is aimed for scientists and students interested in the Earth's atmosphere which is vital for the understanding of environmental changes in the global system Earth.




Physics and Chemistry of the Upper Atmosphere


Book Description

A multitude of processes that operate in the upper atmosphere are revealed by detailed physical and mathematical descriptions of the interactions of particles and radiation, temperatures, spectroscopy and dynamics.




Study of Energy Balance Between Lower and Upper Atmosphere


Book Description

Abstract: Separate energy budgets for the lower atmosphere (0-11 km) and upper atmosphere (> 11 km) are obtained in this report. The Schuster-Schwarzschild (S-S) integral equations of radiative transfer (Schuster 1905; Schwarzschild 1906, 1914) governing the radiation through atmosphere are solved to obtain the radiative fluxes that are required for the energy budget. The back radiation obtained from this analysis agrees with Intergovernmental Panel on Climate Change (IPCC, 2007) data. The standard temperature, pressure and density data required for the analysis is obtained from US Standard Atmosphere (1976). This analytical procedure uses the standard assumptions like one dimensionality, effective absorption coefficient (k) for a mixture of gases, constant flux directional parameter and quasi-static equilibrium. For the lower atmosphere, it has been assumed that all the clouds lie in the 0-11 km region. The ground level value of absorption coefficient group (kp), (kp)o is also obtained. 'p' is the partial pressure of the mixture of radiative gases.




Radiative Forcing of Climate Change


Book Description

Changes in climate are driven by natural and human-induced perturbations of the Earth's energy balance. These climate drivers or "forcings" include variations in greenhouse gases, aerosols, land use, and the amount of energy Earth receives from the Sun. Although climate throughout Earth's history has varied from "snowball" conditions with global ice cover to "hothouse" conditions when glaciers all but disappeared, the climate over the past 10,000 years has been remarkably stable and favorable to human civilization. Increasing evidence points to a large human impact on global climate over the past century. The report reviews current knowledge of climate forcings and recommends critical research needed to improve understanding. Whereas emphasis to date has been on how these climate forcings affect global mean temperature, the report finds that regional variation and climate impacts other than temperature deserve increased attention.
