Fig. 11From: Spatial scale of geomagnetic Pc5/Pi3 pulsations as a factor of their efficiency in generation of geomagnetically induced currentsa Averaged \(R_{I-By}\) spectra for the N–S large- (\(L_{NS}\)) and small-scale (\(S_{NS}\)) pulsations. (\(L_{NS} = L_{\gamma }L_{\varphi }L_P\) in Figure 10, while all the other groups form the \(S_{NS}\) group) ; b frequency dependence of \(R_{I-By} >0.1~\)A\(^2\)/nT\(^2\) fraction for the same groups of pulsationsBack to article page
