Plasmapause surface wave oscillates the magnetosphere and diffuse aurora [PDF]
Nature Communications, 2020 Theoretical studies suggested that plasmapause surface waves related to the sharp inhomogeneity exist and act as a source of geomagnetic pulsations.

Journal of Geophysical Research: Space Physics, 2020 AbstractRecent studies based on CLUSTER, CRRES, and especially on THEMIS satellite data have revealed the statistical behavior of the global plasmapause such as eastward azimuthal plasmapause propagation and radial plasmapause motion between 21 and 07 magnetic local times (MLTs) most likely at postmidnight.

Prediction of Dynamic Plasmapause Location Using a Neural Network
Space Weather, 2021 As a common boundary layer that distinctly separates the regions of high‐density plasmasphere and low‐density plasmatrough, the plasmapause is essential to comprehend the dynamics and variability of the inner magnetosphere.

Remote sensing the plasmasphere, plasmapause, plumes and other features using ground-based magnetometers [PDF]
Journal of Space Weather and Space Climate, 2014 The plasmapause is a highly dynamic boundary between different magnetospheric particle populations and convection regimes. Some of the most important space weather processes involve wave-particle interactions in this region, but wave properties may also ...

Dynamical Simulations of Plasmapause Deformations [PDF]
Space Science Reviews, 2006 Dynamical simulations have been developed at IASB-BIRA to model the deformations of the plasmasphere during geomagnetic substorms and other variations in the level of geomagnetic activity. The simulations are based on the mechanism of plasma instability and use the empirical Kp-dependent electric field E5D.

The distribution of plasmaspheric hiss wave power with respect to plasmapause location
Geophysical Research Letters, 2016 In this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth.

The electron density at the midpoint of the plasmapause
Frontiers in Astronomy and Space SciencesThe high density plasmasphere in the magnetosphere is often separated from a lower density region outside of the plasmasphere, called the plasmatrough, by a sharp gradient in electron density called the plasmapause.

Geophysical Research Letters, 2021 We present observational support for whistler mode waves guidance by the plasmapause gradients based on a case study and statistical analyses. Due to the combined effects of inhomogeneous magnetic fields and plasma densities, whistler mode waves near the

Improving Predictions of the 3D Dynamic Model of the Plasmasphere
Frontiers in Astronomy and Space Sciences, 2021 In this perspective paper, we review and discuss different ways that can be used to improve the predictions of the models of the plasmaspheric region. The density of the background cold plasma and the plasmapause position are very important to determine ...
