A three‐dimensional (3‐D) global hybrid simulation is carried out to study the formation of the dayside low‐latitude boundary layer (LLBL) under a purely northward interplanetary magnetic field (IMF). Magnetic reconnection in both northern and southern hemispheres leads to a continued formation of newly closed field lines on the dayside, and a subsequent formation of the LLBL by capture of the magnetosheath ions on the original magnetosheath field lines, as the newly closed field lines shorten. The formation of the LLBL is associated with the tailward spreading of the transmitted ions along the magnetopause as the newly closed flux tubes convect tailward. Meanwhile, compressional waves and transverse waves in magnetic field are generated in the magnetosphere. The ion distributions in the cusp and the boundary layer show the presence of multiple ion beams of the transmitted magnetosheath ions, as well as ion heating.

“…The time step of particle advance is At --0.0212•1. The advances of particle velocities and magnetic field are accurate to second order in both time and space [Swift, 1996]. The most serious source of errors arises from the finite particle number n per ceil, which causes the fluctuations of physical quantities by an amplitude of -,• 1/x/-• on the scale of grid size.…”

“…The initial ion temperature is assumed to be isotropic, with Tin0 -100T0, where Tmo and To are the initial temperatures in the magnetosphere and the solar wind, respectively. In addition to the ion particle dynamics described above, a cold, dense fluid population occupies the magnetospheric region of r < 6 RE to represent the dense plasma in the inner magnetosphere [Swift, 1996]. Since the electron temperature is much less than the ion temperature in the magnetosheath and the magnetosphere, in our study the electron temperature is assumed to be zero for simplicity.…”

Abstract. A two-dimensional global hybrid simulation is carried out to study the structure of the magnetopause boundary layer in the noon-midnight meridian plane associated with the dayside reconnection. In the simulation the bow shock, magnetosheath, and magnetopause are formed self-consistently by supersonic solar wind passing the geomagnetic field. The dayside reconnection is triggered by imposing a current-dependent resistivity at the subsolar magnetopause. A large-amplitude rotational discontinuity is formed in the quasi-steady reconnection layer in the northern and southern hemispheres. The rotational discontinuity possesses an electron sense, or right-hand polarization in the magnetic field as the discontinuity is formed from the X line, and the magnetic structures in the magnetopause northward and southward of the X line are asymmetric in the cases with a nonzero By component of the interplanetary magnetic field (IMF). However, later the rotational discontinuity tends to evolve to a structure with a smallest field rotational angle and thus may reverse its sense of the field rotation. The Wa16n relation is tested for electron and ion flows in the magnetopause rotational discontinuities with left-hand and right-hand polarizations. Field-aligned currents are generated in the magnetopause rotational discontinuity during the reconnection, and nearly 5% of the magnetopause currents propagate with Alfv•n waves along the field lines into the polar ionosphere. In addition, a weak secondary rotational discontinuity or Alfv•n wave pulse propagates from the reconnection site into the magnetosphere. The sense of the field-aligned currents is investigated for various values of the IMF By. The Hall effects on the structure of the magnetopause boundary layer and the field-aligned currents are discussed.
