Understanding substorm dynamics necessitates an integrative modeling approach combining the magnetospheric and ionospheric systems. This study presents a comprehensive coupled model of magnetosphere-ionosphere (MI) interactions with a focus on substorm electrodynamics. We simulate current systems, energy deposition, and plasma convection using a hybrid MHD-ionospheric electrodynamics framework. The results reveal strong coupling effects during substorm onset, including enhanced field-aligned currents and auroral precipitation. Key outputs align with observed data from SuperDARN and THEMIS missions, validating the model’s efficacy. This work contributes to improving space weather forecasts and real-time monitoring tools.
