| Zusammenfassung |
Intermittent fluctuations are the consequence of the dynamic interactions of
multiple coherent or pseudo-coherent structures of varied sizes in the
stochastic media (Chang, 1999). We briefly review here a recently developed
technique, the Rank-Ordered Multifractal Analysis (ROMA), which is both
physically explicable and quantitatively accurate in deciphering the
multifractal characteristics of such intermittent structures (Chang and Wu,
2008).
The utility of the method is demonstrated using results obtained from
large-scale 2-D MHD simulations as well as in-situ observations of magnetic
field fluctuations from the interplanetary and magnetospheric cusp regions,
and the broadband electric field oscillations from the auroral zone. |
