Magnetic Reconnection Inside Solar Wind Rotational Discontinuity During Its Interaction With the Quasi-Perpendicular Bow Shock and Magnetosheath
(2022-10-12)
Using a three-dimensional global hybrid simulation, we investigate the formation and evolution of ion-scale magnetic reconnection inside an interplanetary rotational discontinuity (RD) owing to its interaction with the ...
Global-scale simulation of foreshock structures at the quasi-parallel bow shock
(2022-09-29)
A two-dimensional, global-scale hybrid simulation is carried out to study the kinetic structure of the quasi-parallel bow shock. In the simulation the bow shock forms by the interaction of the supersonic solar wind and the ...
Kinetic Alfven Waves From Magnetotail to the Ionosphere in Global Hybrid Simulation Associated With Fast Flows
(2022-09-29)
We have used the Auburn Global Hybrid Code in 3-D to study the generation, dynamics, and global structure of kinetic Alfven waves (KAWs) from the magnetotail to the ionosphere. Our results show that KAWs are generated in ...
Reversal of magnetic field rotation in the reconnection layer due to shear flow effects
(2022-09-29)
We investigate the effects of shear flows on the so-called component reconnection, in which the guide field B-y not equal 0, by solving a one-dimensional Riemann problem for magnetopause reconnection using a resistive MHD ...
Global Hybrid Simulations of Interaction Between Interplanetary Rotational Discontinuity and Bow Shock/Magnetosphere: Can Ion-Scale Magnetic Reconnection be Driven by Rotational Discontinuity Downstream of Quasi-Parallel Shock?
(2022-09-29)
Ion-scale magnetic reconnection has been observed downstream of the terrestrial quasi-parallel (Q-parallel to) shock. Whether it is driven by interplanetary discontinuities or turbulent Q-parallel to shock, however, is ...
Global hybrid simulation of mode conversion at the dayside magnetopause
(2022-09-28)
Mode conversion at the magnetopause has been suggested to lead to the generation of kinetic Alfven waves (KAWs) and effective mass transport from the solar wind into the magnetosphere. To investigate the mode conversion ...
Three-dimensional global hybrid simulation of dayside dynamics associated with the quasi-parallel bow shock
(2022-09-29)
A three-dimensional global-scale hybrid simulation is carried out, for the first time, for dynamics of the dayside bow shock-magnetosphere system associated with the quasi-parallel bow shock. A case with IMF along the ...
Magnetic field rotation and transition width in rotational discontinuities and Alfven wave trains
(2022-09-29)
A hybrid simulation is carried out to study the evolution of magnetic field rotations in rotational discontinuities (RDs) and large-amplitude Alfven wave trains (AWTs) whose initial field rotation angle \Delta Phi\ > 180 ...
Foreshock wave interaction with the magnetopause: Signatures of mode conversion
(2022-09-30)
Our previous hybrid simulation (Shi et al., 2013) under a radial interplanetary magnetic field (IMF) and a supercritical solar wind Mach number has shown that foreshock compressional waves originated from the quasi-parallel ...
Global-scale simulation of foreshock structures at the quasi-parallel bow shock
(2020-06-18)
A two-dimensional, global-scale hybrid simulation is carried out to study the kinetic structure of the quasi-parallel bow shock. In the simulation the bow shock forms by the interaction of the supersonic solar wind and the ...
