In the past several studies have been devoted to the understanding of the response of the Earth’s magnetosphere-ionosphere system to the changes of the solar wind and interplanetary conditions. Among the most relevant results the emergence of complexity in the MI dynamics, which manifests in a near-criticality behaviour and multiscale scale-invariant features, has opened new perspectives for the Solar-Terrestrial relationship studies. On the other hand, in the framework of dynamical systems several new tools and methods have been proposed to quantify and characterise the dynamical complexity and its role in nonlinear out-of-equilibrium dynamical systems.

This session aims in discussing the most recent results in the characterisation and forecasting of the complex solar wind-magnetosphere-ionosphere (SMI) coupling and dynamics in response to interplanetary condition changes, both on theoretical and observational side point of view, and to provide an overview of the relevance of dynamical systems approaches in the field of Space Weather modelling and forecast. We invite contributions reporting new insights into the SMI coupling and dynamics using tools developed in the framework of dynamical systems and systems science.
