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,...

Multi-Agent Simulation (MAS) is a widely used paradigm for modeling and simulating real world complex system, ranging from ant colony foraging to online trading. MAS describes a complex system by representing it as a collection of interactive and concurrent objects following a set of predefined...

Field Line Resonances in Earth’s Magnetosphere: A study of their Observation, Characterization and Wave Sources in the Solar Wind
DownloadFall 2015
This thesis is an observational study of field line resonances (FLRs), between 0.5-5 mHz, in the Earth’s magnetosphere, and their correlation with Ultra Low Frequency (ULF) waves in the solar wind. The mechanisms for these phenomena are not yet completely understood and there is still great...

We describe nonlinear resonance absorption of compressional Alfven waves in a model magnetosphere. It is shown that the ponderomotive force of excited standing shear Alfven waves can lead to nonlinear saturation and spatial structuring of field line resonances and that in low-beta plasmas...

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...

The three-dimensional, nonlinear evolution of a shear how (or Kelvin-Helmholtz (KH)) instability driven by a large-amplitude shear Alfven wave (SAW) in the Earth's magnetosphere is studied by using numerical solutions to the complete set of ideal magnetohydrodynamic equations. An initial setup is...

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 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...

Tikhonchuk, Vladimir T., Frycz, P., Rankin, Robert, Samson, John C.
Compressional Alfvén waves in the terrestrial magnetospheric cavity constitute a discrete spectrum of global modes which can resonate with specific components of the continuum spectrum of shear Alfvén wave (SAW) field line resonant frequencies. We investigate the effect of the ponderomotive force...

Rankin, Robert, Degeling, Alex W.
The interaction between relativistic, equatorially mirroring electrons and Pc5 Ultra Low Frequency (ULF) waves in the magnetosphere is investigated using a numerical MagnetoHydroDynamic (MHD) model for waves and a test-kinetic model for electron phase space density (PSD). The temporal and spatial...
