The terrestrial magnetosphere – ionosphere system is strongly driven by interactions with the interplanetary magnetic field (IMF) and solar wind, and so understanding the communication of energy from one to the other is vital in understanding the processes within the magnetosphere. However, the geoeffectiveness of the IMF and solar wind phenomena which drive the magnetosphere varies. For example, variations in IMF clock angle alter the morphology of reconnection at the dayside magnetopause, which is one of the primary methods of energy communication between the two systems. Intertwined with IMF effects, solar wind variability also impacts the magnetosphere; solar wind events of all scales can rapidly restructure terrestrial electrodynamics, and even trigger geomagnetic storms. The focus of this meeting will be on solar wind and IMF control of the magnetosphere – ionosphere system, in particular in two aspects: coupling between solar wind and/or IMF variability with phenomena within the terrestrial system and propagation timescales of these effects through the magnetosphere. Papers on both observations and modelling of this topic will be invited, highlighting results in phenomenon including (but not limited to) ionospheric and magnetospheric current systems, electromagnetic fields and waves, terrestrial radio emissions, ionospheric convection and auroral emission.
