Statistics of the largest geomagnetic storms per solar cycle ( 1844 ± 1993 )
A previous application of extreme-value statistics to the ®rst, second and third largest geomagnetic storms per solar cycle for nine solar cycles is extended to fourteen solar cycles (1844±1993). The intensity of a geomagnetic storm is measured by the magnitude of the daily aa index, rather than the half-daily aa index used previously. Values of the conventional aa index (1868± 1993), supplemen...
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 ...
متن کاملIonospheric redistribution during geomagnetic storms
[1]The abundance of plasma in the daytime ionosphere is often seen to grow greatly during geomagnetic storms. Recent reports suggest that the magnitude of the plasma density enhancement depends on the UT of storm onset. This possibility is investigated over a 7year period using global maps of ionospheric total electron content (TEC) produced at the Jet Propulsion Laboratory. The analysis confir...
متن کاملGeomagnetic Storms Can Trigger Stroke
Although research linking cardiovascular disorders to geomagnetic activity during the past 40 years is accumulating, robust evidence for the effect of geomagnetic activity (the earth’s magnetic field) on stroke occurrence is lacking and remains a matter of controversy. This is because most studies to date are complicated by significant methodological limitations: high likelihood of stroke miscl...
