Sydorenko, Dmytro, Kabin, Konstantin, Rankin, Robert
A nonlinear two-dimensional fluid model describing excitation of the ionospheric Alfven resonator by a shear Alfven wave coming from the magnetosphere is developed. Initially, the plasma is in an equilibrium defined by a balance between the gravity, electric field, and pressure gradient forces....

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...

It is shown that perpendicular gradients in shear Alfvén wave (SAW) dispersion regulate the localization of wave power on nightside geomagnetic L-shells where narrow Field Line Resonances (FLRs) form. We estimate the timescale for this process, ω0tc = 1/equation image, and demonstrate that it is...

This paper presents the results of a linear model for global scale magneto-hydrodynamic (MHD) waves in a compressed dipole model magnetosphere. We examine scenarios where a localized monochromatic source along the magnetopause boundary launches MHD fast mode ultralow frequency (ULF) waves into...

The THEMIS five-probe constellation was launched in 17 February 2007 to study substorms; however its instrumentation and the alignment at distances <1RE among some of the THEMIS probes, particularly in the first period of its mission, provides unique opportunities to study ULF pulsations in the...

Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shock

Kabin, Konstantin, Keika, Kunihiro, Rankin, Robert, Carr, C. M., Carlson, C. W., Glassmeier, Karl-Heinz, Magnes, Werner, Lucek, Elizabeth, McFadden, J. P., Dandouras, Iannis, Auster, H. U., Sibeck, D. G., Fornacon, K.-H., Angelopoulos, Vassilis, Baumjohann, W., Nakamura, Rumi
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and...

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...

Clauer, C. Robert, Rostoker, G., Kabin, Konstantin, Gombosi, Tamas I., DeZeeuw, Darren L., Rankin, Robert, Rae, I. Jonathan, Marchand, Richard, Ridley, Aaron J.
In this paper we investigate the effect of changes in the interplanetary magnetic field ( IMF), solar wind dynamic pressure, and dipole tilt angle on the position of the ionospheric projection of the open-closed field line boundary (OCB) in a magnetohydrodynamic (MHD) model. We carry out a large...

Liu, W., Wanliss, J. A., Kabin, Konstantin, Gombosi, Tamas I., Fenrich, F. R., Rae, I. Jonathan, Ridley, Aaron J., De Zeeuw, Darren L., Rankin, Robert
We compare open-closed field line boundary positions from the BATS-R-US Global MHD model and CANOPUS photometer measurements of red-line emissions. We choose intervals of steady interplanetary and ionospheric conditions in order to adhere to the \"steady-state'' picture that we are trying to...

Significant populations of electrons with energies of tens of keV appear in the Earth's inner central plasma sheet during the substorm expansion phase. Increasing observational evidence indicates that these injections begin at a radially narrow but azimuthally extended transition between very...
