| Abstract: |
To modeling the propagation and interaction of two CMEs, the
three-dimensional (3D) time-dependent, numerical magnetohydrodynamic
(MHD) model is applied. With help of the observation data of
magnetic field and density, the background solar wind is constructed
based on the self-consistent source surface. By means of the
magnetized plasma blob model, two successive CMEs occurring on 2001
March 28 and forming a multiple magnetic cloud (multi-MC) in
interplanetary space is simulated. The dynamical propagation and
interaction of the two CMEs are investigated. We have found that,
the second CME can overtake the first one, and cause compound
interactions and an obvious acceleration of the shock. At L1 point
near the Earth, the two resultant magnetic clouds in our simulation
are consistent with the observations by ACE. |
