Magnetic signatures associated with the time-dependent magnetic reconnection processes at the dayside magnetopause are studied based on two-dimensional compressible MHD simulations. In the simulations, magnetic and plasma signatures resemblant to the observed flux transfer events (FTEs) can be generated either by the magnetic bulges formed during the bursty single X line reconnection (BSXR) or by the magnetic islands (flux tubes) formed during the multiple X line reconnection (MXR). It is found that the FTE magnetic signatures are not exhibited on the magnetospheric side if the FTEs are due to the BSXR process and Bm/Bs≥1.7, where Bm and Bs are the magnetic field strength in the magnetosheath and in magnetosphere, respectively. On the other hand, the bipolar FTE signatures can be detected on both the magnetosphere and magnetosheath sides if the FTEs are caused by the MXR process and Bm/Bs≤2.6. When Bm/Bs>2.6, the bipolar FTE signatures in the magnetosphere site become too small to be detected even if magnetic islands are formed during the MXR process. Furthermore, for Bm/Bs>1, the region for the detection of FTE signatures in the magnetospheric side is smaller than that in the magnetosheath side. Since at the dayside magnetopause the typical value of Bm/Bs is 1--3, the simulation results indicate that more FTE signatures can be detected in the magnetosheath side than in the magnetosphere. It is also found that the MXR process often generates a clear bipolar Bn signature while the BSXR process tends to produce FTEs with a monopolar Bn signature near the reconnection region and a highly asymmetric bipolar Bn signature away from the reconnection region. ¿ American Geophysical Union 1991
