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.
