“Generic” temporal behavior of the flow speed, V (blue), magnetic field, B (red), density, N, (green), and the cosmic ray count-rate change expressed in percent, CR (black), based on the study of a sample of CIRs presented in Paper I. Panel a: simplified, generic, presentation based on the mean values of the amplitudes and timing of the B, N, and CR onsets, peaks, and ends, relative to the onset of V (to see better the relative amplitude of V, it is multiplied by a factor of two). The peak times are marked by vertical dashed lines. Panel b: SEA results; the variations relative to the pre-CIR values are normalized to the peak values, ΔV/Vmax, ΔB/Bmax, ΔN/Nmax, and ΔCR/CRmax. The time Δt = 0 is set at the onset of the V increase.
