The verage morphology of magnetic storms with sudden commencement was studied with 346 magn tic storms that occurred in the years 1902 to 1945. Magnetic recor from 26 observatories were used. The 346 storms were classed into three intensity groups of great, moderate and weak storms, and their morphology was investig ted s par t ly S OR VARI TION WAS ANALYZED INTO WO PARTS, Dst and DS. DS was naly ed harmonically, and its changes with storm time were studied in great detail. The author's present views on stor sudden commencements and on the b ormal nature of t e storm variations at the geomagnetic equator are briefly reviewed. (Author).

The main features of ionospheric-geomagnetic storms and their probable causes are reviewed. Disturbances in short-wave radio propagation during such storms are discussed. The principles of short-term prediction of ionospheric-geomagnetic storms are summarized and all kinds of Izmiran's forecasts are described. The application of these forecasts and current ionospheric data to calculation of usable radio propagation frequencies is explained. This Manualiis of interest to radio-communication operators as well as to geophysicists dealing with this field of science.

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.

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.

Physics of Geomagnetic Phenomena, Volume II covers the advances in geomagnetism and the penetrations into the generation of geomagnetic field phenomena. This book is composed of three chapters and begins with a discussion on various types of phenomenal disturbances, such as ionospheric and geomagnetic disturbance, aurora, and storm. The next chapter describes certain aspects of space geomagnetism based on satellite and rocket observations. This chapter also examines the origins of geomagnetic disturbance phenomena. The last chapter surveys the problems connected with studies of geomagnetic storms and auroras, along with a hydromagnetic model of these phenomena. This book will be of value to physicists, theoreticians, and scientists in allied fields of geomagnetism.

An introduction to geomagnetic storms and the hazards they pose at the Earth’s surface Geomagnetic storms are a type of space weather event that can create Geomagnetically Induced Currents (GICs) which, once they reach Earth’s surface, can interfere with power grids and transport infrastructure. Understanding the characteristics and impacts of GICs requires scientific insights from solar physics, magnetospheric physics, aeronomy, and ionospheric physics, as well as geophysics and power engineering. Geomagnetically Induced Currents from the Sun to the Power Grid is a practical introduction for researchers and practitioners that provides tools and techniques from across these disciplines. Volume highlights include: Analysis of causes of geomagnetic storms that create GICs Data and methods used to analyze and forecast GIC hazard GIC impacts on the infrastructure of the bulk power system Analysis techniques used in different areas of GIC research New methods to validate and predict GICs in transmission systems

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.

Physics of Geomagnetic phenomena, Volume I covers the significant advances in geomagnetism and the penetrations into the generation of geomagnetic field phenomena. This volume is composed of three chapters. Chapter I deals briefly with the discovery and developments in geomagnetism, followed by discussions on some fundamental topics of the field, including the aurora and geomagnetic storms. This chapter also considers the instruments, geomagnetic stations, and the correlations between geomagnetic indices. Chapter II describes the magnetic properties of minerals and various processes of acquisition of remanent magnetization. This chapter also provides palaeomagnetic data for the direction and intensity of the geomagnetic field in ancient times. Chapter III explores geomagnetic variations caused by solar flares and eclipses. This book will prove useful to physicists, students in upper atmospheric and space topics, and scientists in allied fields with a background in geomagnetism.
