Long-term Geomagnetic Indices and their Use in Inferring Solar Wind Parameters in the Past
We discuss three new geomagnetic indices [the Inter-Hour Variability (IHV), Svalgaard and Cliver (2007); the Inter-Diurnal Variability (IDV), Svalgaard and Cliver, 2005; and the Polar-Cap Potential (PCP) Index, Le Sager and Svalgaard (2004)], that are derivable from data available for a century or more. Each of these indices responds directly to either the solar wind magnetic field strength (B)...
متن کاملScaling in long term data sets of geomagnetic indices and solar wind ǫ as seen by WIND spacecraft
Scaling in long term data sets of geomagnetic indices and solar wind ǫ as seen by WIND spacecraft. We study scaling in fluctuations of the geomagnetic indices (AE, AU , and AL) that provide a measure of magnetospheric activity and of the ǫ parameter which is a measure of the solar wind driver. Generalized structure function (GSF) analysis shows that fluctuations exhibit self-similar scaling up ...
متن کاملThe statistical dependence of auroral absorption on geomagnetic and solar wind parameters
Data from the Imaging Riometer for Ionospheric Studies (IRIS) at Kilpisjärvi, Finland, have been compiled to form statistics of auroral absorption based on seven years of observations. In a previous study a linear relationship between the logarithm of the absorption and the Kp index provided a link between the observations of precipitation with the level of geomagnetic activity. A better fit to...
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 کاملThe influence of solar wind turbulence on geomagnetic activity
The importance of space weather and its forecasting is growing as interest in studying geoeffective processes in the Sun – solar wind – magnetosphere – ionosphere coupled system is increasing. In this paper higher order statistical moments of interplanetary magnetic field and geomagnetic SYM-H index fluctuations are compared. The proper description of fluctuations in the solar wind can elucidat...
