摘要：

A new MHD simulation method for reproducing a realistic and time-varying global heliospheric modelling is developed using solar-wind speed data from interplanetary sintillation (IPS) and photospheric magnetic data from optical observations. The IPS together with the magnetic data provide us inner boundary conditions which include both co-rotating solar-wind speed distribution and magnetic field distributions using a tilted current sheet model. Hence it enables us to reproduce dynamical co-rotating wind-wind interaction and also magnetic field structures such as an oscillating equatorial magnetic neutral sheet in a three-dimensional heliosphere. In our preliminary results of this method, a realistic and oscillating equatorial neutral sheet and wind-wind interactions are shown both in the interplanetary space and the heliosheath.
