Abstract: The paper addresses nonlinear phenomena that control the interaction between plasma flow (solar wind) and magnetic barrier (magnetosphere). For the first time we demonstrate that the dominant solar wind kinetic energy: (1) excites boundary resonances and their harmonics which modulate plasma jets under the bow shock; (2) produces discrete 3-wave cascades, which could merge into a turbulent-like one; (3) jet produced cascades provide the effective anomalous plasma transport inside and out of the magnetosphere; (4) intermittency and multifractality characteristics for the statistic properties of jets result in a super-ballistic turbulent transport regime. Our results could be considered as suggestive for the space weather predictions, for turbulent cascades in different media and for the laboratory plasma confinement (e.g. for fusion devices).
