Book excerpt: Summary of the NATO Advanced Research Workshop on Physical Signatures of Magnetospheric Boundary Layer Processes T A POTEMRA, M I PUDOVKIN, R W SMITH, V M VASYLIUNAS and A EGELAND 451 PREFACE These proceedings are based on the invited talks and selected research reports presented at the NATO Advanced Workshop on "PHYSICAL SIGNATURES OF MAGNETOSPHERIC BOUNDARY LAYER PROCESSES", held at Sundvolden Hotel, Norway, 9.-14.May 1993. The international political and scientific communities have gradually realized that the Earth's environment is more fragile than previously believed. This has led to the establishment of international research programmes directed toward the understanding of "Global Change". The Earth's magnetosphere, "the Earth-space", is a part of our environment, and physical processes in the magnetosphere and coupling between the solar energy stream, the solar wind, and the Earth-space are important in the complete understanding of our environment. Variations in the electromagnetic and particle energy output of the Sun have a significant effect on global changes. The energy transfer mechanisms at the days ide magnetospheric boundary layers and their ionospheric signatures are perhaps even more important to solar terrestrial research than the night-side processes in this connection. The dayside boundary layers and the polar cusps are the Earth's windows to outer space. The present NATO ARW was the latest in a series of conferences focused on dayside magnetospheric phenomena. It is five years since the preceding Workshop on "Electromag netic Coupling in the Polar Clefts and Caps" was held at Lillehammer in September 1988.

Book Synopsis Characteristics of the Magnetospheric Boundary Layer and Magnetopause Layer in High Time Resolution by :
Download or read book Characteristics of the Magnetospheric Boundary Layer and Magnetopause Layer in High Time Resolution written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A basic problem of magnetospheric physics is to determine how and where solar wind mass, momentum and energy is transferred to the magnetosphere. IMP 6 plasma and magnetic field data indicate that the closed magnetospheric boundary layer is always present adjacent to and earthward of the magnetopause layer at all locations equatorward of the entry layer and plasma mantle. All IMP 6 crossings show some magnetosheath-like plasma earthward of the magnetopause layer and the boundary layer electron spectra are often indistinguishable from the nearby magnetosheath electron spectra. In 24 out of 40 crossings, no change in density or electron spectra is observed near the magnetopause layer. In most remaining cases, changes in the plasma parameters occur primarily in the boundary layer. Observed boundary layer bulk plasma flow always has an anti-sunward component and often has a cross-field component. Energetic electron pitch angle distributions indicate that the boundary layer is on closed field lines. During six IMP 6 crossings near local noon, equatorward of the cusp regions, boundary layer plasma flow was observed to have an anti-sunward component consistent with flow away from the subsolar region or the nearby magnetosheath. The observations are not consistent with a primary source in the cusp region or any other nonlocal source. It is concluded that the boundary layer is populated primarily by direct plasma transport through the magnetopause layer.

Book Synopsis Magnetic Cloud Boundary Layers and Magnetic Reconnection by : Yi Wang
Download or read book Magnetic Cloud Boundary Layers and Magnetic Reconnection written by Yi Wang and published by Springer. This book was released on 2015-08-21 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on magnetic reconnection processes in the boundary layer of the interplanetary magnetic cloud. Magnetic reconnection is an important and frontier topic in the realm of physics. Various physical phenomena can be observed during the reconnection process but lots of them are not fully understood. This thesis provides the first observational evidence of energetic electrons associated with magnetic reconnection in the solar wind and discusses the particle acceleration problems. In addition, after analyzing the particle flux variations in Magnetic Cloud Boundary Layer, the thesis proposes a possible new criterion for the identification of magnetic reconnection in the solar wind. These tantalizing results could be particular clues to understand the dynamical problems in magnetic reconnection processes.
Book Synopsis Outer Magnetospheric Boundaries: Cluster Results by : Goetz Paschmann
Download or read book Outer Magnetospheric Boundaries: Cluster Results written by Goetz Paschmann and published by Springer Science & Business Media. This book was released on 2005-12-07 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the stream of plasma emitted from the Sun (the solar wind) encounters Earth's magnetic field, it slows down and flows around it, leaving behind a cavity, the magnetosphere. The magnetopause is the surface that separates the solar wind on the outside from the Earth's magnetic field on the inside. Because the solar wind moves at supersonic speed, a bow shock must form ahead of the magnetopause that acts to slow the solar wind to subsonic speeds. Magnetopause, bow shock and their environs are rich in exciting processes in collisionless plasmas, such as shock formation, magnetic reconnection, particle acceleration and wave-particle interactions. They are interesting in their own right, as part of Earth's environment, but also because they are prototypes of similar structures and phenomena that are ubiquitous in the universe, having the unique advantage that they are accessible to in situ measurements. The boundaries of the magnetosphere have been the target of direct in-situ measurements since the beginning of the space age. But because they are constantly moving, changing their orientation, and undergoing evolution, the interpretation of single-spacecraft measurements has been plagued by the fundamental inability of a single observer to unambiguously distinguish spatial from temporal changes. The boundaries are thus a prime target for the study by a closely spaced fleet of spacecraft. Thus the Cluster mission, with its four spacecraft in a three-dimensional configuration at variable separation distances, represents a giant step forward. The present 20th volume of the ISSI Space Science Series represents the first synthesis of the exciting new results obtained in the first few years of the Cluster mission.

Book Synopsis The Magnetospheric Cusps: Structure and Dynamics by : Theodore A. Fritz
Download or read book The Magnetospheric Cusps: Structure and Dynamics written by Theodore A. Fritz and published by Springer Science & Business Media. This book was released on 2006-02-23 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers will address the question "What is the Magnetospheric Cusp?" and what is its role in the coupling of the solar wind to the magnetosphere as well as its role in the processes of particle transport and energization within the magnetosphere. The cusps have traditionally been described as narrow funnel-shaped regions that provide a focus of the Chapman-Ferraro currents that flow on the magnetopause, a boundary between the cavity dominated by the geomagnetic field (i.e., the magnetosphere) and the external region of the interplanetary medium. Measurements from a number of recent satellite programs have shown that the cusp is not confined to a narrow region near local noon but appears to encompass a large portion of the dayside high-latitude magnetosphere and it appears that the cusp is a major source region for the production of energetic charged particles for the magnetosphere. Audience: This book will be of interest to space science research organizations in governments and industries, the community of Space Physics scientists and university departments of physics, astronomy, space physics, and geophysics.

Available in PDF, EPUB and Kindle. Book excerpt: IMP 6 observations of the plasma boundary layer (PBL) and magnetopause layer (MPL) of the earth's magnetosphere indicate that plasma in the low-latitude portion of the PBL is supplied primarily by direct transport of magnetosheath plasma across the MPL and that this transport process is relatively widespread over the entire sunward magnetospheric boundary.
Book Synopsis Polar Cap Boundary Phenomena by : Jøran Moen
Download or read book Polar Cap Boundary Phenomena written by Jøran Moen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings are based on the invited talks and selected research reports presented at the NATO Advanced Study Institute (ASI) on "POLAR CAP BOUNDARY PHENOMENA" held at Longyearbyen, Svalbard, June 4 - 13, 1997. The role of the polar cap and its boundary is very substantial in solar-terrestrial physics. At this NATO AS! a major change in thinking on the "cusp" precipitation region in the high-latitude days ide upper atmosphere was reflected, at least for intervals when the interplanetary magnetic field (IMF) is directed southward. It is likely that this has implications for northward IMF as well. The change comes from the now almost complete acceptance of the concept of magnetosheath particle entry along open magnetic field lines and the evolution of the precipitation into the upper atmosphere with time elapsed since magnetic reconnection which opened the field line. A key prediction of this view is that the low-latitude boundary layer (LLBL) is on open field lines.
