Title: Fractal time statistics of AE-index burst waiting times: evidence of metastability
Authors: Consolini, G.*
De Michelis, P.*
Keywords: magnetospheric physics
magnetotail dynamics
fractal time statistics
AE-index
Issue Date: 2002
Publisher: EGU
Title of journal: Nonlinear Processes in Geophysics
Series/Report no.: 5-6 / 9 (2002)
Abstract: 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).
