Three-dimensional Simulation Study of the Interactions of Three Successive CMEs During November 4-5, 1998

Using a 3D magnetohydrodynamics (MHD) numerical simulation, we investigate the propagation and interaction of the three halo CMEs originating from the same active region during 1998 November 4-5 from the Sun to Earth.本研究采用三维磁流体力学（magnetohydrodynamics, MHD）数值模拟，探究了1998年11月4日至5日期间源自同一太阳活动区的三起晕状日冕物质抛射（halo CMEs）从太阳传播至地球的过程及其相互作用。
