| Zusammenfassung |
| A test for deterministic dynamics in a time series data, namely the 0–1 test
(Gottawald and Melbourne, 2004, 2005), is used to study the magnetospheric
dynamics. The data, corresponding to the same time period, of the auroral
electrojet index AL and the magnetic field component Bz of the
solar wind magnetic field measured at 1 AU are used to compute the parameter
K, which is zero for non-chaotic and unity for chaotic systems. For the
magnetosphere and also for the turbulent solar wind, K has values
corresponding to a nonlinear dynamical system with chaotic behaviour. This
result is consistent with the Lyapunov exponents computed from the same time
series data. |
