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.

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

Nobel symposium No. 54 on High Latitude Magnetospheric/Iono spheric Plasma Physics was organized in Kiruna, Sweden on March 22-25, 1982 by Kiruna Geophysical Institute and EISCAT Scientific Association. Some 50 leading experts from Western Europe, America and USSR were invited to the Symposium. One main purpose of the Symposium was to prepare for the intense European research effort in space plasma physics in the middle 1980's, in which the EISCAT facilities and the Swedish satellite Viking are two of the more important constituents. The prograuune of the symposium was tied to the physics of those regions of near space where EISCAT and Viking are expected to pro vide important new observational results. This is rather well covered by the t it Ie of these proceedings: High Lat itude Space Plasma Physics. The first two sessions dealt with the physics of the high latitude ionosphere and the third one with how this part of near space is affected by the properties of the solar wind and the interplanetary magnetic field. The remaining three sessions covered fairly extensively the high latitude magnetospheric physics at altitudes of 1-2 earth radii, which is the main scien tific object of the Viking project. The Prograuune COllDlittee of the Kiruna Nobel Symposium was composed of the following European scientists: P. Bauer (Issy-les-Moulineaux), R. Bostrom (Uppsala), C.G. FalthallDlar (Stockholm), T. Hagfors (Kiruna, Cochairman), o. Holt (Troms, s), B. Hultqvist (Kiruna, Cochairman), H. Kohl (Lindau), J. Oksman (Oulu), H. Rishbeth (Chilton), and L. Stenflo (Ume!).

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.

This book builds on the fluid and kinetic theory of equilibria and waves presented in a companion textbook, Basic Space Plasma Physics (by the same authors), but can also serve as a stand-alone text. It extends the field covered there into the domain of plasma instability and nonlinear theory.The book provides a representative selection of the many possible macro- and microinstabilities in a space plasma, from the Rayleigh-Taylor and Kelvin-Helmholtz to electrostatic and electromagnetic kinetic instabilities. Their quasilinear stabilization and nonlinear evolution and their application to space physics problems are treated. The chapters on nonlinear theory include nonlinear waves, weak turbulence and strong turbulence, all presented from the viewpoint of their relevance to space plasma physics. Special topics include auroral particle acceleration, soliton formation and caviton collapse, anomalous transport, and the theory of collisionless shocks.

How did electrons in the high atmosphere and space around the Earth come to acquire their speeds and energies? This intriguing question lies at the heart of understanding how high-energy electrons create the spectacular displays of the ^IAurora Borealis and ^IAurora Australis. Electron Acceleration in the Aurora and Beyond explores the mysteries of these phenomena and others involving the acceleration of electrons in the magnetosphere, in the solar wind, at the Sun and in the Cosmos. This book presents a new approach to understanding this fascinating subject by treating the acceleration medium as a plasma. Using this new insight we can see that electron acceleration may well be caused by waves rather than steady potential differences. This unique approach is clearly explained in a lively and engaging style. Quantitative formulae, experiments, practical demonstrations and computer programs enable us to investigate for ourselves how the model works. The theory is further illustrated by comparing acceleration in space with particle accelerators in the nuclear physics laboratory (and even on the sports field!) Questions and exercises with answers are supplied to stimulate further thinking. ^IElectron Acceleration in the Aurora and Beyond is a thought-provoking book for graduate and post-doctoral space scientists.

The Earth's Ionosphere: Plasma Physics and Electrodynamics emphasizes the study of plasma physics and electrodynamics of the ionosphere, including many aeronomical influences. The ionosphere is somewhat of a battleground between the earth's neutral atmosphere and the sun's fully ionized atmosphere, in which the earth is embedded. One of the challenges of ionosphere research is to know enough about these two vast fields of research to make sense out of ionospheric phenomena. This book provides insights into how these competing sources of mass, momentum, and energy compete for control of the ionosphere. Some of the topics discussed include the fundamentals of ionospheric plasma dynamics; equatorial plasma instabilities; high-latitude electrodynamics; and instabilities and structure in the high-latitude ionosphere. Throughout this text only the region above 90 km are discussed, ignoring the D region entirely. This publication is a good source of information for students and individuals conducting research on earth’s ionosphere.

During the past decade our understanding of plasma physics has witnessed an explosive growth due to research in two areas: work directed toward controlled nuclear fusion and work in space physics. This book addresses the growing need to apply these complementary discoveries to astrophysics. Today plasma is recognized as the key element to understanding the generation of magnetic fields in planets, stars and galaxies, the accel- eration and transport of cosmic rays, and many other phenomena occurring in interstellar space, in radio galaxies, stellar atmospheres, quasars, and so forth.

Although interesting in its own right, due to the ever-increasing use of satellites for communication and navigation, weather in the ionosphere is of great concern. Every such system uses trans-ionospheric propagation of radio waves, waves which must traverse the commonly turbulent ionosphere. Understanding this turbulence and predicting it are one of the major goals of the National Space Weather program. Acquiring such a prediction capability will rest on understanding the very topics of this book, the plasma physics and electrodynamics of the system. Fully updated to reflect advances in the field in the 20 years since the first edition published Explores the buffeting of the ionosphere from above by the sun and from below by the lower atmosphere Unique text appropriate both as a reference and for coursework
