Abstract: We report on the first comprehensive numerical simulation of a space weather event, starting with th generation of a coronal mass ejection (CME). The simulation follows this transient solar wind disturbance as it evolves into a magnetic cloud and travels through interplanetary space towards Earth, where we predict its interaction with the terrestrial magnetosphere-ionosphere system. The model is based on a magnetohydrodynamic (MHD) approach, utilizing adaptive mesh refinement (AMR) on a parallel computer to reduce the computational time.

Keywords: space environment modeling, space weather, high performance computing, parallel computing, solution adaptive mesh refinement
