[PEM14-15] Response of the Earth’s magnetosphere and ionosphere to the small-scale magnetic flux rope in solar wind by the MHD simulation
Keywords:small-scale magnetic flux rope, magnetosphere and ionosphere , cross polar cap potential
The simulation results show that the bow shock is located at about 14.6 RE and the magnetopause is located at about 10.24 RE in both cases. However, ionospheric phenomena show the different feature for two cases. The cross polar cap potential becomes small during the northward even though magnitude of magnetic field becomes large for +Z axis of magnetic flux rope. And the cross polar cap potential increase that is governed by magnitude of magnetic field as well as southward BZ for +Y axis of magnetic flux rope.
