By performing a three-dimensional (3-D) global hybrid simulation, we investigated the characteristics of the quasi-parallel magnetosheath of the terrestrial bow shock, which is formed due to the interaction of the solar wind with the earth’s magnetosphere. Current sheets with widths several of ion inertial lengths are found to be produced in the magnetosheath after the upstream large amplitude electromagnetic waves penetrate the shock and are then compressed in the downstream. Magnetic reconnection consequently occurs in these current sheets, where high-speed ion flow jets are identified in the outflow region. Simultaneously, flux ropes with the extension along the direction about several earth’s radii are also observed during such a process. Our simulation shed new insight on the mechanism for the occurrence of magnetic reconnection in the quasi-parallel shocked magnetosheath.
