Book Synopsis Cyclonic and Geomagnetic Storms by : Victoria P. Banks
Download or read book Cyclonic and Geomagnetic Storms written by Victoria P. Banks and published by . This book was released on 2015 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar activity causes changes in the magnetic field on the surface of the Earth. If these changes are insignificant, they do not affect life on Earth. However, rapid variations of the geomagnetic field, the so-called magnetic storms, which have the character of shock waves, may adversely affect living organisms (including humans), and the technical systems that people use. The book presents a conceptual design that allows prediction of electrical power system emergency conditions caused by magnetic storms. Finally, the authors' present a comprehensive analysis of perturbations in the low- and mid-latitude ionosphere during moderate recurrent geomagnetic storms.

Book Synopsis Chapter The Highest Geomagnetic Storms of the Solar Cycle Observed at Ground Level by : C. E. Navia
Download or read book Chapter The Highest Geomagnetic Storms of the Solar Cycle Observed at Ground Level written by C. E. Navia and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We report two ground-level observations, of geomagnetic storms of different origins; they are among the highest geomagnetic storms, in the solar Cycle 24. The first is St. Patrick's Day storm on March 17, 2015, originated by the impact on Earth's atmosphere of coronal mass ejections (CMEs), the storm reaching the condition of G4 (severe) level, in the NOAA geomagnetic scale. The second included the major geomagnetic storm whose origin is attributed to the interaction with the Earth of a High-Speed Stream (HSS) ahead of a positive polarity coronal hole on October 7, 2015. This storm reached the condition G3 (strong) level. We give emphasis to observations detected by the New-Tupi muon telescopes, located at sea level in Brazil (22.53° S, 43.13° W). We present a study of these observations in correlation with observations reported by multipoint space-based measurements, such as the ACE at Lagrange Point L1 and the geostationary GOES weather satellite, including two global geomagnetic indices and several ground-based detectors. Some considerations on the influence of these geomagnetic storms in the Earth weather are reported.

Book Synopsis Behavior of High-latitude Irregularities During Geomagnetic Disturbances by : Zwi Houminer
Download or read book Behavior of High-latitude Irregularities During Geomagnetic Disturbances written by Zwi Houminer and published by . This book was released on 1980 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scintillation observations of VHF and UHF transmissions from geostationary satellites at Goose Bay have been used to study the average characteristics of the high latitude irregularity region. The paper describes the average time development and mean diurnal pattern of irregularities during 58 magnetic storms in 1971-1976. The diurnal variation at Goose Bay shows two peaks of scintillation activity. One peak occurs during the afternoon hours, while the second occurs during the night. The average diurnal pattern is independent of type of storm. diurnal and seasonal effects appear only in the first day of storm commencement and not in the following days which show a very similar diurnal picture.

Book Synopsis The Average Morphology of Geomagnetic Storms with Sudden Commencement by : Masahisa Sugiura
Download or read book The Average Morphology of Geomagnetic Storms with Sudden Commencement written by Masahisa Sugiura and published by . This book was released on 1960 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average morphology is described of geomagnetic storms with sudden commencement. A numerical intensity index was assigned to each of 346 storms occurring in 1902--45. On the basis of these indices the storms were divided into three sets, of 136 weak, 136 moderate, and 74 great storms. Their morphology was studied separately. For weak storms records were analyzed from 26 magnetic observatories, ranging in geomagnetic latitude from 80 deg N to 48 deg S; and for moderate and great storms, from 19 observatories, 80 deg N to 1 deg S. The stormtime variation Dst and the disturbance longitudinal inequality DS were determined for the first three storm days for different latitudes. The DS variation was obtained, and harmonically analyzed, for each of the first 8 quarter-day intervals and for the succeeding three 8-hour intervals. New features of storm morphology during the first few hours of storm time were discovered: namely, that DS reaches its maximum in about two or three hours from the storm commencement, and that its phase rapidly changes during the first few storm hours.

Book Synopsis The Relationship Between Magnetic Storms and Atmospheric Circulation by : B. A. Yakovlev
Download or read book The Relationship Between Magnetic Storms and Atmospheric Circulation written by B. A. Yakovlev and published by . This book was released on 1967 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation of data on strong and very strong magnetic storms of at least two days duration, recorded by the Murmansk Division of the Institute of Terrestrial Magnestism, Ionosphere, and Radio Wave Propagation of the Academy of Sciences of the USSR during the period 1 January 1955 to 31 July 1959, has shown that there is a tendency of magnetic storms to recur at approximately equal periods of time. The most frequently observed periods were: 14 plus or minus 1, 26 plus or minus 1, 29 plus or minus 1 and 56 plus or minus 1 days. Cyclogenesis developed more actively from the second day after the commencement of the magnetic storm to the second day after its termination, and the development of low cyclones into high-lvevel cyclones was accelerated. At the time of magnetic storms during the cold season, there is a tendency for cyclonic activity to intensify from Iceland toward the Barents Sea. In the warm season, during magnetic storms, there is a tendency for the temperature to rise in this same region. The article includes an analysis of processes during two magnetic storms. (Author).
Book Synopsis Extreme Events in Geospace by : Natalia Buzulukova

Book Synopsis Geomagnetic Storms by : Department of Homeland Security. Office of Risk Management and Analysis
Download or read book Geomagnetic Storms written by Department of Homeland Security. Office of Risk Management and Analysis and published by . This book was released on 2011 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geomagnetic storms - a type of space weather that creates disturbances that affect the planet's magnetic field - have the potential to cause significant damage across the globe with a single event. Severe geomagnetic storms can disrupt the operation of electric power transmission systems and critical infrastructures relying on space-based assets. A geomagnetic storm that degrades the electric power grid would affect not only the energy sector but the transportation, communications, banking, and finance sectors, as well as government services and emergency response capabilities. Despite the potentially serious consequences of a severe geomagnetic storm, a literature review indicates that the state of the art for assessing the security risk from geomagnetic storms is still in development. There are examples of analyses that describe threat, vulnerability, and consequence, but they are not integrated, primarily because of the weakness in the threat analysis. Without a sense of the likelihood of such events or at least a mechanism for relative comparisons, cost-benefit analyses have been unable to demonstrate the utility of investing either in hardening or in testing and maintaining operational procedures. The Federal government lacks comprehensive national-level geomagnetic storm risk management assessments and strategies, and no standing entity exists to coordinate cross-Federal government geomagnetic storm risk analysis. This Issue Brief suggests that the Federal government should consider whether it is appropriate to conduct a formal, comprehensive risk assessment regarding severe geomagnetic storms.

Book Synopsis Corotating Interaction Regions by : A. Balogh
Download or read book Corotating Interaction Regions written by A. Balogh and published by Springer Science & Business Media. This book was released on 2000-01-31 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gives a comprehensive and integrated overview of current knowledge and understanding of corotating interaction regions (CIRs) in the solar wind. It is the result of a workshop at ISSI, where space scientists involved in the Ulysses, Pioneer, Voyager, IMP-8, Wind, and SOHO missions exchanged their data and interpretations with theorists in the fields of solar and heliospheric physics. The book provides a broad synthesis of current understanding of CIRs, which form at the interface between the fast solar wind originating in the northern and southern coronal holes and the slow solar wind that originates near and within coronal streamers surrounding the heliomagnetic equator. CIRs are the dominant structure in the heliosphere near and beyond Earth on the declining phase and near the minimum of the 11-year solar activity cycle. Particles energized at the shocks that bound CIRs at heliospheric distances beyond the orbit of Earth are the dominant energetic particle population observed in the outer heliosphere at these times. Papers included in this volume cover the subject of CIRs from their dissipation in the outer hemisphere, and include discussions of complexities associated with their evolution with distance from the Sun, their three-dimensional structure, and the myriad effects that CIRs have on energetic particles throughout the heliosphere. The book is intended to provide scientists active in space physics research with an up-to-date status report on current understanding of CIRs and their effects in the heliosphere, and also to serve the advanced graduate student with introductory material on this active field of research.

Book Synopsis Earth's Climate Response to a Changing Sun by : Katja Matthes
Download or read book Earth's Climate Response to a Changing Sun written by Katja Matthes and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, scientists have been fascinated by the role of the Sun in the Earth's climate system. Recent discoveries, outlined in this book, have gradually unveiled a complex picture, in which our variable Sun affects the climate variability via a number of subtle pathways, the implications of which are only now becoming clear. This handbook provides the scientifically curious, from undergraduate students to policy makers with a complete and accessible panorama of our present understanding of the Sun-climate connection. 61 experts from different communities have contributed to it, which reflects the highly multidisciplinary nature of this topic. The handbook is organised as a mosaic of short chapters, each of which addresses a specific aspect, and can be read independently. The reader will learn about the assumptions, the data, the models, and the unknowns behind each mechanism by which solar variability may impact climate variability. None of these mechanisms can adequately explain global warming observed since the 1950s. However, several of them do impact climate variability, in particular on a regional level. This handbook aims at addressing these issues in a factual way, and thereby challenge the reader to sharpen his/her critical thinking in a debate that is frequently distorted by unfounded claims.
