Scientific paper

A cone model-based halo CME representation is inserted into the combined WSA (corona) and ENLIL (heliosphere) models. We studied the performance of the combined models by analyzing different halo CME propagation and evolution to the L1 point and comparing the result to ACE observations. We simulated CMEs related to a number of geomagnetic storms and events, including the series of the October 2003 Halloween Storm CMEs and the fall AGU storm CME on December, 2006. We introduced 4 parameters characterizing cone model performance: CME arrival time, magnitude of impact, magnetopause standoff distance, duration of the event. We also describe real-time setup for the ENLIL cone model to trigger CME alert capability at the Community Coordinated Modeling Center.
