Dominant harmonic eigenstructures of \(E_{{\text{r}}}\) along the closed field line in the noon-meridian plane at \(L = 8~R_{{\text{E}}}\). a The dominant fundamental harmonic oscillations of \(E_{{\text{r}}}\) between \(t = 0 - 200~\Omega _{{i0}}^{{ - 1}}\) in time sequence. b The RIPs of the fundamental, second and third harmonic mode structures of \(E_{{\text{r}}}\) along the dipole-like field line in the noon-meridian plane at \(L = 8~R_{{\text{E}}}\). The vertical dashed line marks the equator position. The relative magnitude of oscillations for the fundamental harmonic is also marked at the right bottom in a
