| Research Abstract |
The generating mechanism of large-amplitude(tens of mV/m) electric field fluctuation observed in magnetotail reconnection sites has been investigated by using results of observational data analysis and numerical simulations synthetically. The results strongly suggest that the emerging region of the large-amplitude electric field fluctuation is downstream far from the diffusion region of magnetic reconnection. Since the generating mechanism has been thought to be strongly related with the plasma dynamics in the diffusion region, we have to reconsider the physical meaning of the large-amplitude electric field fluctuation.
