Pitch angle scattering of electrons can limit the stably trapped particle flux in the magnetosphere and precipitate energetic electrons into the ionosphere. Whistler mode waves generated by a temperature anisotropy can mediate this pitch angle scattering over a wide range of radial distances and...
We experimentally investigate the behaviour of a line-source plume falling through a finite two-layer stratified ambient where the depth of the upper ambient layer increases in time. Laboratory observations suggest one of two possible flow regimes depending on the value of 𝜆 , which represents...
We consider electron acceleration by kinetic Alfvén waves in the equatorial inner magnetosphere and plasma sheet boundary layer. The competition between the accelerating effect of the wave parallel electric field and mirror force acting on particles in an inhomogeneous background magnetic field...
Measurements from ground-based magnetometers and riometers at auroral latitudes have demonstrated that energetic (similar to 30-300 keV) electron precipitation can be modulated in the presence of magnetic field oscillations at ultralow frequencies. It has previously been proposed that an...
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...
The propagating source method for solving the time-dependent Boltzmann equation describing particle propagation in a magnetically turbulent medium is extended to a more realistic case that includes focusing and adiabatic deceleration. The solutions correspond to beam propagation in the solar...
Magnetohydrodynamic, field line resonances in the Earth's magnetosphere can have very large velocity shears and field-aligned currents. Auroral radar measurements of high-latitude resonances indicate that the velocities associated with the resonances in the E and F regions am often substantially...
We present a case study of Field Line Resonances (FLRs) in the dayside magnetosphere, observed in both electric and magnetic field components at multiple L-shells near the equator. The event measured by the five THEMIS probes and the nearby GOES and Geotail satellites provides a unique...
Ultra-low frequency (ULF) field line resonances (FLRs) cause oscillations in F-region plasma flows and can be detected in SuperDARN measured line-of-sight (l-o-s) velocities. In this paper, we characterize a ULF wave event with coordinated use of SuperDARN HF radars, optical instrumentation,...
“Zebra stripes” are newly found energetic electron energy-spatial (L shell) distributed structure with an energy between tens to a few hundreds keV in the inner radiation belt. Using high-quality measurements of electron fluxes from Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE)...
