Fig. 9From: 3-D global hybrid simulations of magnetospheric response to foreshock processesCase I: radial profiles of wave power spectra of \(E_{{\text{r}}}\) (a) and \(B_{\phi }\) (b) as a function of \(L\) in the noon-meridian plane. The white dashed lines mark the first 7 harmonic modes of the FLRs. The local Alfvén speed is given in cBack to article page
