This book was released on 2021-12-03 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear Wave and Plasma Structures in the Auroral and Subauroral Geospace presents a comprehensive examination of the self-consistent processes leading to multiscale electromagnetic and plasma structures in the magnetosphere and ionosphere near the plasmapause, particularly in the auroral and subauroral geospace. It utilizes simulations and a large number of relevant in situ measurements conducted by the most recent satellite missions, as well as ground-based optical and radar observations to verify the conclusions and analysis. Including several case studies of observations related to prominent geospacer events, the book also provides experimental and numerical results throughout the chapters to further enhance understanding of how the same physical mechanisms produce different phenomena at different regions of the near-Earth space environment. Additionally, the comprehensive description of mechanisms responsible for space weather effects will give readers a broad foundation of wave and particle processes in the near-Earth magnetosphere. As such, Nonlinear Wave and Plasma Structures in the Auroral and Subauroral Geospace Nonlinear Wave and Plasma Structures in the Auroral and Subauroral Geospace is a cutting-edge reference for space physicists looking to better understand plasma physics in geospace. - Presents a unified approach to wave and particle phenomena occurring in the auroral and subauroral geospace - Summarizes the most current theoretical concepts related to the generation of the large-scale electric field near the plasmapause by flows of hot plasma from the reconnection site - Includes case studies of the observations related to the most "famous events during the last 20 years as well as a large number of experimental and numerical results illustrated throughout the text

Available in PDF, EPUB and Kindle. Book excerpt: International Geophysics Series, Volume 2: Physics of the Aurora and Airglow explores certain physical aspects of aurora and airglow. This volume is composed of 13 chapters and begins with surveys of the theory and spectroscopic and photometric analyses of radiation from the upper atmosphere. The subsequent chapters treat the geographic distribution of aurora and its physical processes in the atmosphere. Other chapters examine the theory of hydrogen emission in aurora, resonance scattering by atmospheric sodium, the excitation of the oxygen red lines in the airglow, and an atlas of the auroral spectrum. A chapter focuses on the analysis of twilight observations for emission heights. The concluding chapters discuss the theory of day airglow, as well as the spectral photometry and excitation of the nightglow. This book is of value to geophysicists, theoreticians, and scientists of the allied fields of geophysics.
Download or read book Auroral Physics written by David J. Knudsen and published by Springer. This book was released on 2021-08-27 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume surveys our current scientific understanding of the terrestrial aurora. It is organized into eleven reviews detailing theoretical and observational aspects of characteristic auroral morphologies, and how these in turn are organized according to local time, latitude, and activity level. Popular descriptions often attribute the aurora to the interaction of charged particles from the solar wind with atoms in the upper atmosphere. In fact, most auroras are not the result of direct entry of solar wind particles. Rather, as detailed in this volume, auroral particle acceleration and generation of auroral forms occur primarily within the magnetosphere. Importantly, many key aspects of the aurora – most notably, the physical mechanisms responsible for the generation of discrete arcs – are still unexplained, and auroral physics continues to be an active area of scientific research. Each review chapter therefore includes a summary of open questions for further investigation. Providing the first comprehensive review of the terrestrial aurora in two decades, this book will aid both active researchers and newcomers interested in understanding the current state of the field.

Download or read book Auroral Plasma Physics written by Götz Paschmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gives a broad synthesis of the current knowledge and understanding of the plasma physics behind the aurora. The aurora is not only one of the most spectacular natural phenomena on Earth, but the underlying physical processes are expected to be ubiquitous in the plasma universe. Recognizing the enormous progress made over the last decade) through in situ and groundbased measurements as well as theoretical modelling, it seemed timely to write the first comprehensive and integrated book on the subject. Recent advances concern the clarification of the nature of the acceleration process of the electrons that are responsible for the visible aurora, the recognition of the fundamental role of the large-scale current systems in organizing the auroral morphology, and of the interplay between particles and electromagnetic fields.
Download or read book The Northern Light written by A. Brekke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Nordic literature a remarkable discussion of the northern light appears in Kongespeilet (The King's Mirror) a thirteenth-century Norwegian chronicle. It is described in vivid detail as the following translated excerpts demonstrate: These northern lights have this peculiar nature, that the darker the night is, the brighter they seem, and they always appear at night but never by day, most frequently in the densest darkness and rarely by moonlight. In appearance they resemble a vast flame of fire viewed from a great distance. It also looks as if sharp points were shot from this flame up into the sky; these are of uneven height and in constant motion, now one, now another darting highest; and the light appears to blaze like a living flame. Three different theories for the origin of the northern light were suggested in this book. Numerous naturally occurring heavenly phenomena have been observed and enjoyed as long as the Earth has been inhabited, but hardly any of them has stirred man's imagination, curiosity and fear as much as the northern light. The northern light is certainly one of the most spectacular of nature's phenomena.

Book excerpt: Just over one hundred years ago Kristian Birkeland looked into the night sky of his native Norway and saw in the beautiful Northern Lights a mystery waiting to be solved. Determined to prove to the world his bold theory about the heavens above, this misunderstood genius began a quest that would take him from Norway's ice mountains to the deserts of Africa, and across a continent ravaged by war. It was a quest that alienated friends and family, ruined his health and sanity, and ended in his mysterious death in a Japanese hotel in 1917. Lucy Jago brilliantly tells the fascinating and tragic story of Kristian Birkeland, the man who saw in the night sky a secret that no one else could see, but who died trying to convince the world of his vision.

Book excerpt: Electric green pierced by neon blue, shocking pink spinning into violent red, and shimmering purple sidled up against deep indigo: never before have you seen such high-octane colors in the sky, and never before has a book shown the northern lights-aurora borealis-in such vivid color. In Northern Lights, photographers Calvin Hall and Daryl Pederson bring to print nearly a hundred photographs of this amazing natural phenomenon, shot from remote locations all over Alaska and using no filters or digital enhancement. Just as fascinating are the legends, myths, and science surrounding this polar phenomenon, described by George Bryson. As 2002 marks the peak viewing time of the northern lights in an eleven-year cycle, this book brings the elusive magic of the northern lights to stargazers near and far.

Download or read book An Infrared Spectral Radiance Code for the Auroral Thermosphere AARC written by J. R. Winick and published by . This book was released on 1987 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: A first principles scientific model for predicting the spectral radiance from the auroral thermosphere seen by an earthlimb observer is described. This model, and the resulting Auroral Atmospheric Radiance Code (AARC), describe the energy deposition in the thermosphere by primary auroral electrons and the ensuing effects. The latter include electron production and production of nonequilibrium concentrations of vibrationally and electronically excited states, by photochemical means, and by energy transfer. Relaxation of the states by collisions and radiation is described, and the transmission of the infrared radiation emitted from these states is treated. Currently, the model considers four radiators: the nitric oxide vibrational fundamental and first overtone at 2.8 and 5.3 micro the NO+ fundamental at 4.3 mirco, and the CO2 asymmetric- stretch (NU -3 mode) emission at 4.3 micro. The prompt optically optically thin emitters (NO and NO+) are treated in terms of stored, precalculated tables of efficiencies (photons per ion-pair).
