This article describes the relationship between shear Alfvén waves and auroral electron
acceleration, with an emphasis on long-period standing waves that correlate with redline …

Recent observations have indicated that in addition to the classical “inverted‐V” type
electron acceleration, auroral electrons often have a field‐aligned distribution that is broad …

An analytical treatment is given of two‐dimensional, quasi‐steady collisionless reconnection
on the basis of the generalized Ohm's law, including the effects of the Hall current and scalar …

This paper presents results from a numerical study of nonlinear interactions between ultra‐
low‐frequency (ULF) electromagnetic waves and the magnetospheric‐ionospheric plasma …

The spectrum of toroidal standing shear Alfvén waves (SAWs) is derived for a stretched
magnetic field line geometry that is approximated by the Tsyganenko 96 magnetic field …

Using a new two‐dimensional nonlinear finite element model, we investigate the interaction
of dispersive shear Alfvén wave (SAW) field line resonances (FLRs) and ion acoustic waves …

The tearing mode instabilities were numerically studied in two distinct models: the finite
electron inertial magnetohydrodynamics (MHD) and the electron MHD (EMHD). The finite …

Pulsed ionospheric flows (PIFs) in the cusp foot-print have been observed by the
SuperDARN radars with periods between a few minutes and several tens of minutes. PIFs …

By assuming a general isotropic pressure distribution P= P (ψ, α), where ψ and α are three‐
dimensional scalar functions labeling the field lines with B=∇ ψ×∇ α, we have derived a set …

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 …
