Different FTE signatures generated by the bursty single X line reconnection and the multiple X line reconnection at the dayside magnetopauseThis paper examines magnetic signatures associated with the time-dependent magnetic reconnection processes at the dayside magnetopause, using two-dimensional compressible MHD simulations. Emphasis is placed on the different flux-transfer-event (FTE) signatures generated by the bursty single X-line reconnection (BSXR) and the multiple X-line reconnection processes. It is shown that the FTE magnetic signatures are not exhibited on the magnetospheric side if the FTEs are due to the BSXR process and the ratio between the magnetic field strength in the magnetosheath to that in the magnetosphere is not less than 1.7. The simulation results are compared with satellite observations.
