AbstractBy proposing a two-dimensional triggering model with concentrically circular closed magnetic field line structure, numerical research is made on the asymmetric propagation feature of coronal mass ejection (CME) in two cases emerging at the solar northern latitudes 10degrees and 45degrees respectively. The numerical results can qualitatively explain some features of CME event observed by the spacecraft SOHO and show that: (i) In these two cases, the triggering model can initiate CME with an asymmetric closed magnetic field structure. (ii) Closed magnetic structure of CME event will keep deflecting to the current sheet when it propagates away from the sun and this deflecting effect mostly happens within tens of solar radii before CME travels finally along the current sheet. (iii) The triggering model emerging at different locations can introduce CME events with different magnetic shapes. This shape happens to be circular and crescent when the triggering model emerges at the northern latitudes 10degrees and 45degrees, respectively.
