| Zusammenfassung |
This paper demonstrates
that intermittent magnetic field fluctuations in the plasma sheet exhibit
transitory, localized, and multi-scale features. We propose a multifractal-based
algorithm, which quantifies intermittence on the basis of the statistical
distribution of the "strength of burstiness", estimated within a
sliding window. Interesting multi-scale phenomena observed by the Cluster
spacecraft include large-scale motion of the current sheet and bursty bulk flow
associated turbulence, interpreted as a cross-scale coupling (CSC) process.
Key words. Magnetospheric physics (magnetotail;
plasma sheet) – Space plasma physics (turbulence) |
