| Zusammenfassung |
| Recent observations
and analyses evidenced that the magnetotail, as well as the magnetospheric
dynamics are characterised by a scale-free behaviour and intermittence.
These results, along with numerical simulations on cellular automata,
suggest that the observed scale-invariance may be due to forced and/or
self-organised criticality (FSOC), meaning that the magnetotail
operates near a marginally stable state (Chang, 1999). On the other hand,
it was underlined that a complex magnetic field topology in the geotail
regions may play a relevant role in the impulsive energy relaxation (Consolini
and Chang, 2001. |
