Rankin, Robert, Ridley, Aaron J., Gombosi, Tamas I., Clauer, C. Robert, Watanabe, Masakazu, Kabin, Konstantin, Sofko, George J.
On the basis of magnetohydrodynamic simulation results for northward interplanetary magnetic field ( IMF) and significant dipole tilt, we describe internal reconnection processes that occur earthward of the magnetopause subsequent to magnetopause reconnection. We discuss the associated...

Mitochondrial cytochrome oxidase I and 11 genes were sequenced for two invasive alien birch (Betula L. [Betulaceae]) leaf-mining sawflies, Profenusa thomsoni (Konow, 1886) (Hymenoptera: Tenthredinidae) and Scolioneura betuleti (King, 1816) (Hymenoptera: Tenthredinidae), accidentally introduced...

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...

A two-dimensional nonlinear multi-fluid MHD model of the ionosperic Alfven resonator is presented. The resonator is excited by a packet of shear Alfven waves propagating downward toward the ionosphere from high altitudes. It is shown that the nonlinear (ponderomotive) force of standing...

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...

Veit, R. R., Banks, J. E., Holmes, E. E., Lewis, M. A.
Most of the fundamental elements of ecology, ranging from individual behavior to species abundance, diversity, and population dynamics, exhibit spatial variation. Partial differential equation models provide a means of melding organism movement with population processes and have been used...

Resonant drift echoes in electron phase space density produced by dayside Pc5 waves following a geomagnetic storm

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...

Watt, Clare E. J., Wright, D. M. , Rankin, Robert, Rae, I. Jonathan
We present self-consistent kinetic simulations of the electron response to finite duration shear Alfven wave pulses in a magnetized plasma. In Earth's magnetosphere, the evidence suggests that parallel electric fields in inertial scale shear Alfven waves can accelerate electrons in the...

Rankin, Robert, Samson, John C., Watt, Clare E. J.
Using 1D Vlasov drift-kinetic computer simulations, it is shown that electron trapping in long period standing shear Alfvén waves (SAWs) provides an efficient energy sink for wave energy that is much more effective than Landau damping. It is also suggested that the plasma environment of low...
