Nuclear Magnetohydrodynamic Emp, Solar Storms, and Substorms
In addition to a fast electromagnetic pulse (EMP), a high altitude nuclear burst produces a relatively slow magnetohydrodynarnic EMP (MHD EMP), whose effects are like those from solar storm geomagnetically induced currents (SS-GIC). The MHD EMP electric field E < 10 V/m and lasts < 10 sec, whereas for solar storms E > 10 V/m and lasts >10 sec. Although the solar storm electric field is lower th...
متن کاملIx. Solar Radio Emission
The emission of solar flares at millimeter wavelengths is of great interest both in its own right and because it is generated by the energetic electrons which also emit gamma rays. Since high-resolution imaging at gamma-ray energies is not presently possible, millimeter observations can act as a substitute. Except for that class of flares known as gamma-ray flares the millimetric emission is op...
متن کاملRadio Halos in future surveys in the radio continuum
Aims. Giant radio halos are mega-parsec scale synchrotron sources detected in a significant fraction of massive and merging galaxy clusters. Radio halos provide one of the most important pieces of evidence of non-thermal components in large-scale structure. Their statistical properties can be used to discriminate among various models for their origin. Therefore, theoretical predictions of the o...
متن کاملGeomagnetic storms driven by ICME- and CIR-dominated solar wind
[1] The interaction of the solar wind and the Earth’s magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejections (ICMEs) compared to solar wind dominated by corotating interaction regions (CIRs). We perform a superposed epoch study of the effects of ICMEand CIR-dominated solar wind upon the storm-time pla...
متن کاملTerrestrial Response To Eruptive Solar Flares: Geomagnetic Storms
During the interval of August 1978December 1979, 56 unambiguous fast forward shocks were identified using magnetic field and plasma data collected by the ISEE-3 spacecraft. Because this intervaI is at a solar maximum we assume the streams causing these shocks are associated with coronal mass ejections and eruptive solar flares. For these shocks we shall describe the shockstorm relationship for ...
