摘要：
Recent observation of magnetic field fluctuations in the geotail regions evidenced the occurrence of sporadic, localized multiscale turbulent fluctuations. In this work, we approach these fluctuations from a statistical point of view, showing the existence of non-trivial scaling features and similarity of the observed scaling properties with those of a stochastic process generated by an Ornstein-Uhlembeck-Cauchy equation. Our results will be discussed in the framework of the recent stochastic view of the geotail dynamics in terms of a forced and/or self-organized criticality.
