Finite element modeling of nonlinear dispersive field line resonances: Trapped shear Alfvén waves inside field‐aligned density structures

Marchand, Richard, Rankin, Robert, Wanliss, J. , Tikhonchuk, V. T., Lu, J. Y.
Using a new two- dimensional nonlinear finite element model, we investigate the interaction of dispersive shear Alfven wave ( SAW) field line resonances ( FLRs) and ion acoustic waves in Earth's magnetosphere. We solve the full set of nonlinear reduced MHD equations self- consistently in...

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...

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...

Ionospheric electron heating by resonant standing shear Alfvén waves in Earth's magnetosphere is investigated. It is demonstrated that in field line resonances (FLRs), electron heating by Alfvén waves produces ionization and large changes in the ionospheric Pedersen conductivity. This leads to a...

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...

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...

Nonlinear dynamics of a dispersive field line resonance (FLR) is investigated in a dipolar magnetic geometry using a new finite element code TOPO. Time dependent dispersion and steepening of the perpendicular Alfvén velocity profile lead to the acceleration of dispersive effects and 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...
