Abstract: |
Coronal mass ejections (CMEs) have been identified as a prime causal link between solar activity and large, non-recurrent, geomagnetic storms. Modeling of the origin of CMEs is still in the research phases and it is not expected that real events can be routinely simulated in near future. Therefore, we have developed a intermediate modeling system which uses fitted coronagraph observations, specifies 3D ejecta, and drives the 3D numerical magnetohydrodynamic code ENLIL which uses solar wind source maps derived from various analytic, empirical, and numerical coronal models. We simulated a number of heliospheric events which enabled us to analyze the match between different parameters predicted by the model and observed by spacecraft. Attention is given to development of tools facilitating prediction of solar wind parameters at planets and spacecraft. |
