Precipitation and nonlinear effects in geomagnetic field line resonancesournal of Geophysical Research: Space Physics, 108(A4), [pp
Download2003
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...

Recent increases in Arctic freshwater flux affects Labrador Sea convection and Atlantic overturning circulation
Download2016
Chambers, Don, Dixon, Timothy H., Bonin, Jennifer, van den Broeke, M. R., Yang, Qian, Ribergaard, Mads H., Mortensen, John, Myers, Paul G.
The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland’s ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW),...

Resonant drift echoes in electron phase space density produced by dayside Pc5 waves following a geomagnetic storm
Download2008
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...

Response of the Mediterranean Sea thermohaline circulation to observed changes in the winter wind stress field in the period 1980-1993
Download1999
Josey, Simon, Samuel, Sarah, Myers, Paul G., Haines, Keith
This paper seeks to model changes in deep water production in the eastern Mediterranean induced by changes in winter wind stress. An analysis of individual monthly wind stress fields over the Mediterranean for 1980–1993 from the SOC flux data set shows that an intensification of the winter mean...

Sensitivity of the subpolar North Atlantic to Last Glacial Maximum surface forcing and sea ice distribution in an eddy-permitting regional ocean model
Download2006
Myers, Paul G., Bush, Andrew B. G., Yang, Duo
The impact of paleoatmospheric forcing and sea ice distribution on the circulation of the subpolar North Atlantic is examined in a regional eddy-permitting ocean model. We focus on water mass formation and the pathway of the North Atlantic Current. Paleofluxes are obtained from a coupled...

The influence of high-frequency atmospheric forcing on the circulation and deep convection of the Labrador Sea
Download2015
Holdsworth, Amber M., Myers, Paul G.
The influence of high-frequency atmospheric forcing on the circulation of the North Atlantic Ocean with emphasis on the deep convection of the Labrador Sea was investigated by comparing simulations of a coupled ocean–ice model with hourly atmospheric data to simulations in which the...

Kabin, Konstantin, Marchand, Richard, Lu, J. Y., Rankin, Robert, Tikhonchuk, Vladimir T.
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...
