Kinetic Alfven waves in three-dimensional magnetic reconnection
(2020-06-03)
Alfvenic waves are believed to be fundamentally important in magnetic reconnection. Kinetic dynamics of particles can break the Alfven speed limit in the evolution and propagation of perturbations during reconnection. In ...
Global hybrid simulation of mode conversion at the dayside magnetopause
(2020-06-05)
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 ...
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 ...
Generation of anomalous flows near the bow shock by its interaction with interplanetary discontinuities
(2020-06-30)
Two-dimensional hybrid simulations using a curvilinear coordinate system are carried out to study the interaction of the Earth's bow shock (BS) with an interplanetary directional discontinuity. In particular, plasma flow ...
Reversal of magnetic field rotation in the reconnection layer due to shear flow effects
(2020-06-18)
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 ...
Dipolarization fronts as earthward propagating flux ropes: A three-dimensional global hybrid simulation
(2020-06-03)
Dipolarization fronts (DFs) as earthward propagating flux ropes (FRs) in the Earth's magnetotail are presented and investigated with a three-dimensional (3-D) global hybrid simulation for the first time. In the simulation, ...
Foreshock wave interaction with the magnetopause: Signatures of mode conversion
(2020-06-01)
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 ...
Magnetosheath Reconnection Before Magnetopause Reconnection Driven by Interplanetary Tangential Discontinuity: A Three-Dimensional Global Hybrid Simulation With Oblique Interplanetary Magnetic Field
(2020-05-28)
Terrestrial dayside dynamics associated with a southward turning, oblique interplanetary magnetic field (IMF) carried by an interplanetary tangential discontinuity (TD) is investigated by performing a three-dimensional ...
Ion Acceleration Inside Foreshock Transients
(2020-05-28)
Recent observations upstream of Earth's bow shock have revealed that foreshock transients can not only accelerate solar wind ions by reflection at their upstream boundaries but may also accelerate ions inside them. Evidence ...
The ion temperature gradient: An intrinsic property of Earth's magnetotail
(2020-06-01)
Although the ion temperature gradient along (X GSM) and across (Z GSM) the Earth's magnetotail, which plays a key role in generating the cross‐tail current and establishing pressure balance with the lobes, has been extensively ...
