Comparison of the open‐closed separatrix in a global magnetospheric simulation with observations: The role of the ring current

Kabin, Konstantin, Lu, J. Y., Rankin, Robert, Gombosi, Tamas I., Watt, Clare E. J., Ridley, Aaron J., Toth, Gabor, Milan, Steve E., Zhang, Jichun, Rae, I. Johnathan, Clauer, C. Robert, De Zeeuw, Darren L., Fenrich, Frances
The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...

We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e., raytracing) with the equation of transfer of radiation in an anisotropic...

The process of magnetospheric radiation belt electron transport driven by ULF waves is studied using a 2-D ideal MHD model for ULF waves in the equatorial plane including day/night asymmetry and a magnetopause boundary, and a test kinetic model for equatorially mirroring electrons. We find that...

The adiabatic drift-resonant interaction between relativistic, equatorially mirroring electrons and narrowband, Pc 5 ultra low frequency (ULF) waves in the magnetosphere is investigated using a time-dependent magnetohydrodynamic (MHD) wave model. Attention is focused on the effect of a ULF wave...

Recent simulation results have revealed that energetic electron bursts are produced cyclically at the shock reformation period upstream of reforming shocks and are qualitatively very different from the continuous beam expected from time-stationary shocks (Yuan et al., 2007a). This paper extends...

A new interactive M-I coupling model that describes the dynamic interaction between magnetospheric dispersive waves, compressional modes, and auroral electron precipitations is applied to investigate the geomagnetic electromagnetic pulsations observed in Earth's magnetosphere in terms of...

We present theory and ground-based observations of field-line resonances (FLRs) excited in Earth's magnetosphere. Three FLR observations are reported, which correspond to large-scale standing shear Alfven wave (SAW) oscillations on nightside field lines extending from premidnight to close to...

A two-dimensional nonlinear multi-fluid MHD model of the ionosperic Alfven resonator is presented. The resonator is excited by a packet of shear Alfven waves propagating downward toward the ionosphere from high altitudes. It is shown that the nonlinear (ponderomotive) force of standing...

Origin of the interhemispheric potential mismatch of merging cells for interplanetary magnetic field BY‐dominated periods

Kabin, Konstantin, Rankin, Robert, Gombosi, Tamas I., Sofko, George J., Ridley, Aaron J., Watanabe, Masakazu, Clauer, C. Robert
When the dawn-to-dusk component of the interplanetary magnetic field (IMF B-Y) is dominant, ionospheric convection exhibits a basic two-cell pattern with significant dawn-dusk and interhemispheric asymmetries. For IMF B-Y > 0 the duskside merging cell potential in the Northern Hemisphere is much...

Tikhonchuk, V. T., Prakash, M., Rankin, Robert
The structure of auroral arcs sustained by field line resonances (FLRs) is determined using a model that describes the interplay between ionospheric feedback, nonlinear, and dispersive effects in a curvilinear geomagnetic topology. The model includes modulation of Pedersen conductance by hundreds...
