Abstract. Taking into account the primary mechanisms for transfer particles and energy into the magnetosphere, we have studied the dynamical characteristics of High-Intensity Long-Duration Continuous Auroral Activity (HILDCAA) events using a long-term geomagnetic database (1975–2012). The Recurrence Quantification Analysis method was applied on the auroral electrojet indices during HILDCAA events to characterize their dynamics. After, we compared those results with the ones obtained for geomagnetically quiet periods when there was no appreciable auroral activity. As result, the quantification allowed to find specific characteristics of these two distinct regimes. The HILDCAA events can be described as unique processes responsible for complex transfers of energy and particles from the solar wind plasmas into the magnetosphere-ionosphere system. We also suggest that the scenario of these processes is related to concurrent magnetospheric mechanisms (magnetic reconnection and viscous interaction). At last, we reinforce the potential applicability of the RQA method for characterization of various nonlinear geomagnetic processes related to these phenomenology.

Short summary
The effects of the Sun upon the Earth's atmosphere occur in several ways. Significant electrodynamic coupling processes transfer particles and energy from the solar wind into the Earth's geomagnetic environment. Applied to the dynamical characteristics of High-Intensity, Long-Duration, Continuous Auroral Activity (HILDCAA) events, nonlinear analysis tools as RQA aids to unravel peculiarities related to two concurrent space mechanisms known as magnetic reconnection and viscous interaction.
