| Zusammenfassung |
| In this paper, we have analyzed the interplanetary magnetic field (IMF)
obtained by ACE satellite during the coronal mass ejection events. The
characterization of the IMF fluctuations was performed using the singular
power spectra deviations obtained from a wavelet transform modulus maxima
(WTMM) approach. The results suggest the existence of different multifractal
processes driving the intermittency during and after the CME events on the
IMF time series. The characteristic time scales found, using the WTMM, and
possible related physical mechanisms are discussed in the context of
nonlinear interplanetary magnetic field response. |
