Magnetic reconnection is studied numerically by means of a two dimensional MHD codes. The initial magnetic field configuration is the two-dimensional dipole field, and the simulation model involves magnetic reconnection driven by the magnetized plasma flow. Strong plasma jetting, plasmoid formation and its fast ejection are observed in the downstream region. The dependence of reconnection rate on the incoming energy flux is found to be very sensitive, while the magnitude of the resistivity does not influence much on the reconnection rate. The simulation results are discussed in the context of the geomagnetic substorm.
