This book was released on 2021-12-07 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System provides a systematic understanding of Magnetosphere-Ionosphere-Thermosphere dynamics. Cross-scale coupling has become increasingly important in the Space Physics community. Although large-scale processes can specify the averaged state of the system reasonably well, they cannot accurately describe localized and rapidly varying structures in space in actual events. Such localized and variable structures can be as intense as the large-scale features. This book covers observations on quantifying coupling and energetics and simulation on evaluating impacts of cross-scale processes. It includes an in-depth review and summary of the current status of multi-scale coupling processes, fundamental physics, and concise illustrations and plots that are usable in tutorial presentations and classrooms. Organized by physical quantities in the system, Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System reviews recent advances in cross-scale coupling and energy transfer processes, making it an important resource for space physicists and researchers working on the magnetosphere, ionosphere, and thermosphere. Describes frontier science and major science around M-I-T coupling, allowing for foundational understanding of this emerging field in space physics Reviews recent and key findings in the cutting-edge of the science Discusses open questions and pathways for understanding how the field is evolving

Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the outcome of an American Geophysical Union Chapman Conference on longitude and hemispheric dependence of ionospheric space weather, including the impact of waves propagating from the lower atmosphere. The Chapman Conference was held in Africa as a means of focusing attention on an extensive geographic region where observations are critically needed to address some of the fundamental questions of the physical processes driving the ionosphere locally and globally. The compilation of papers from the conference describes the physics of this system and the mechanisms that control ionospheric space weather in a combination of tutorial-like and focused articles that will be of value to the upper atmosphere scientific community in general and to ongoing global magnetosphere-ionosphere-thermosphere (MIT) modeling efforts in particular. A number of articles from each science theme describe details of the physics behind each phenomenon that help to solve the complexity of the MIT system. Because this volume is an outcome of the research presented at this first space science Chapman Conference held in Africa, it has further provided an opportunity for African scientists to communicate their research results with the international community. In addition, the meeting and this conference volume will greatly enhance the space science education and research interest in the African continent and around the world. Ionospheric Space Weather includes articles from six science themes that were discussed at the Chapman Conference in 2012. These include: Hemispherical dependence of magnetospheric energy injection and the thermosphere-ionosphere response Longitude and hemispheric dependence of storm-enhanced densities (SED) Response of the thermosphere and ionosphere to variability in solar radiation Longitude spatial structure in total electron content and electrodynamics Temporal response to lower-atmosphere disturbances Ionospheric irregularities and scintillation Ionospheric Space Weather: Longitude Dependence and Lower Atmosphere Forcing will be useful to both active researchers and advanced graduate students in the field of physics, geophysics, and engineering, especially those who are keen to acquire a global understanding of ionospheric phenomena, including observational information from all longitude sectors across the globe.

This book was released on 1992 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers presented at these meetings provide an updated review of the area and also cover a wide range of current research topics. This volume contains 46 selected papers covering the whole spectrum of modelling approaches, including analytical, empirical, semi-empirical and numerical models. A proportion of the papers deal with the energetics, dynamics and composition of just the thermosphere, whilst others are concerned with ionospheric behaviour at low, middle and high latitudes. Coupling phenomena figure prominently and numerical simulations are presented to show the coupling processes, feedback mechanisms and time delays associated with the interactions between the magnetosphere and ionosphere, the magnetosphere and thermosphere, and the mid-latitude ionosphere and plasmasphere.

Available in PDF, EPUB and Kindle. Book excerpt: The Dynamical Ionosphere: A Systems Approach to Ionospheric Irregularity examines the Earth’s ionosphere as a dynamical system with signatures of complexity. The system is robust in its overall configuration, with smooth space-time patterns of daily, seasonal and Solar Cycle variability, but shows a hierarchy of interactions among its sub-systems, yielding apparent unpredictability, space-time irregularity, and turbulence. This interplay leads to the need for constructing realistic models of the average ionosphere, incorporating the increasing knowledge and predictability of high variability components, and for addressing the difficulty of dealing with the worst cases of ionospheric disturbances, all of which are addressed in this interdisciplinary book. Borrowing tools and techniques from classical and stochastic dynamics, information theory, signal processing, fluid dynamics and turbulence science, The Dynamical Ionosphere presents the state-of-the-art in dealing with irregularity, forecasting ionospheric threats, and theoretical interpretation of various ionospheric configurations. Presents studies addressing Earth’s ionosphere as a complex dynamical system, including irregularities and radio scintillation, ionospheric turbulence, nonlinear time series analysis, space-ionosphere connection, and space-time structures Utilizes interdisciplinary tools and techniques, such as those associated with stochastic dynamics, information theory, signal processing, fluid dynamics and turbulence science Offers new data-driven models for different ionospheric variability phenomena Provides a synoptic view of the state-of-the-art and most updated theoretical interpretation, results and data analysis tools of the "worst case" behavior in ionospheric configurations

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth's ionosphere is an ionized region of space in the upper atmosphere, starting around 80 km and extending to higher altitudes, comprised of ions and electrons made primarily from solar photo-ionization of neutral particles. Historically, the Earth's ionosphere is stratified into layers referred to as the D, E, and F-regions with the D-region occurring at the base of the ionosphere, followed by the E-region, and then the F-region for altitudes above 150 km. Complex current systems occurring within the ionosphere can result in charge accumulation and the development of polarization electric fields. In the F-region ionosphere, electric fields cause the plasma to drift in a direction perpendicular to both the applied electric field (E) and the Earth's background magnetic field (B). The E×B plasma drifts are the main driver of plasma transport perpendicular to magnetic field lines, and are an important parameter for controlling the distribution of plasma at low latitudes. A comprehensive understanding of the equatorial E × B plasma drifts can improve space weather forecasting which can positively impact radio-based communication system, such as GPS, that rely on radio waves that traverse the ionosphere. This study is partitioned into two parts and analyzes the variability of equatorial F-region plasma drifts. Focus and attention is given to the height variation of the drifts. The first part of this dissertation is an experimental study that utilizes long-term observations of the equatorial plasma drifts made by the incoherent scatter radar (ISR) at the Jicamarca Radio Observatory to derive local time versus height profiles of the mean plasma drifts for different season and for different levels of solar activity. Additional analysis uses day-to-day altitude profiles to determine the magnitude and variability of height gradients in the vertical plasma drifts. The second part of this study focuses on a modeling approach to analyze and improve our understanding of the plasma drifts. This analysis includes an effort to develop an empirical model of the geomagentically quiet-time vertical plasma drifts using the random forest machine learning algorithm that is trained and validated using Jicamarca ISR observations. We also develop and utilize numerical physics-based models that rely on a two-dimensional field line integrated description of the electrodynamics in the low-latitude ionosphere. These models are used to analyze the relative contribution of various sources on the development of equatorial plasma drifts. Additionally, we evaluate the ability of widely used climatological models (IRI, NRLMSISE, HWM, IGRF) of the ionosphere and thermosphere to produce a realistic morphology of equatorial F-region plasma drifts.
