On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell. Van Allen twin Probes observed a sharp electron flux dropout with clear...

Blanco, Mauricio, Artemyev, Anton V., Rankin, Robert
In this paper we study the interaction of kinetic Alfven waves generated near the equatorial plane of the magnetosphere with electrons having initial energies up to similar to 100 eV. Wave-particle interactions are investigated using a theoretical model of trapping into an effective potential...

Kelvin‐Helmholtz unstable magnetotail flow channels: Deceleration and radiation of MHD waves
Download2014
Turkakin, Hava, Rankin, Robert, Mann, Ian R.
The Kelvin-Helmholtz instability (KHI) of magnetotail flow channels associated with bursty bulk flows (BBFs) is investigated. MHD oscillations of the channel in both kink and sausage modes are investigated for KHI, and both the primary and secondary KHIs are found that drive MHD waves. These...

Magnetospheric field‐line resonances: Ground‐based observations and modelingournal of Geophysical Research: Space Physics, 110(A10), [pp

Mann, I. R., Kabin, Konstantin, Donovan, E. F., Lu, J. Y., Rankin, Robert, Rae, I. Jonathan, Marchand, Richard
We present theory and ground-based observations of field-line resonances (FLRs) excited in Earth's magnetosphere. Three FLR observations are reported, which correspond to large-scale standing shear Alfven wave (SAW) oscillations on nightside field lines extending from premidnight to close to...

Spanswick, Emma, Kabin, Konstantin, Donovan, Eric, Rankin, Robert, Samson, John C.
Significant populations of electrons with energies of tens of keV appear in the Earth's inner central plasma sheet during the substorm expansion phase. Increasing observational evidence indicates that these injections begin at a radially narrow but azimuthally extended transition between very...

On the importance of the choice of wind stress forcing to the modeling of the Mediterranean Sea circulation
Download1998
Myers, Paul G., Josey, Simon, Haines, Keith
A 1/4° degree ocean general circulation model is used to examine the role that four different wind stress climatologies play on the circulation of the Mediterranean. The wind stress climatologies examined are those derived from numerical weather prediction models (National Meteorological Center...

Precipitation and nonlinear effects in geomagnetic field line resonancesournal of Geophysical Research: Space Physics, 108(A4), [pp

Tikhonchuk, V. T., Prakash, M., Rankin, Robert
The structure of auroral arcs sustained by field line resonances (FLRs) is determined using a model that describes the interplay between ionospheric feedback, nonlinear, and dispersive effects in a curvilinear geomagnetic topology. The model includes modulation of Pedersen conductance by hundreds...

Self‐consistent wave‐particle interactions in dispersive scale long‐period field‐line‐resonances
Download2007
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...
