    • ...Therefore, the inclusion of the electron continuity equation in the self‐consistent MI coupling scheme is an inevitable element for description of the auroral dynamical behaviors [Atkinson, 1970; Sato, 1978; Watanabe et al., 1993; Doe et al., 1995; Blixt and Brekke ,1 996;Karlsson and Marklund, 1998; Lysak and Song, 2002; Cran‐McGreehin et al., 2007; Streltsov, 2007; Yoshikawa et al., 2011]...
    • ... field can be generated by the breakage of the Hall current, that is, how much of the curl‐free part of the Hall current is confined in the auroral ionosphere by generating the secondary polarization field and then forming a Hall‐Pedersen closing circuit, hence how much of the residual part of the curl‐free Hall current can be flowing out to the magnetosphere by forming the MI coupled FAC system [Amm et al., 2011; Fujii et al., 2011; Yoshikawa ...
    • ... into parallel and antiparallel propagating shear Alfvén wave to the ambient magnetic field, (2) the shear Alfvén wave reflection process including (3) the scale‐dependent electrostatic coupling process [Lysak and Dum, 1983; Vogt and Haerendel, 1998; Vogt, 2002] through the linearized Knight relation [Knight, 1973; Lyons, 1980], (4) two‐layer ionosphere model [Amm et al., 2008; Fujii et al., 2011], (5) dynamic conductance variations ...
    • ...In this case, the advection speed of plasma density increases with the increase of g and the propagating direction is controlled by the curl‐free part of the total ionospheric current including the Hall current [Yoshikawa et al., 2011]...
    • ...Equation (A4) means that the Pedersen current divergence is equal to the resultant current carrier flux divergencearisingwhentheparallelelectronflux(carriestheFAC) cannot seamlessly convert to the perpendicular flux (carries the curl‐free part of the Hall current) and instead the ion perpendicular flux carries the curl‐free part of the Pedersen current for current conservation [Yoshikawa et al., 2011]...
