| Title: | Study of halo CME propagation using combined WSA-ENLIL models. |
| Abstract: |
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 parameters characterizing cone model performance: CME arrival time, magnitude of impact, magnetopause standoff distance. We study the dependence of model output on 3 cone model parameters: 1) initial velocity; 2) ratio of CME material density to ambient plasma density; 3) cone radius (opening angle). |
