Magnetospheric chaos and dynamical complexity response during storm time disturbance

Abstract. In this study, we examine the magnetospheric chaos and dynamical complexity response to disturbance storm time (Dst) solar wind electric field (VBs) during different categories of geomagnetic (minor, moderate major storm). The series data Dst VBs are analysed for a period 9 years using non-linear dynamics tools (maximal Lyapunov exponent, MLE; approximate entropy, ApEn; delay vector variance, DVV). We found significant trend between each parameter storm. MLE ApEn values indicate that chaotic responses high minor storms, reduce at storms decline further storms. However, obtained from with no difference periods associated minor, test non-linearity in reveals strongest features. Based on these findings, features as input output system suggest non-linear, consistently stochastic nature.
