Electrodynamics of the high-latitude ionosphere. Technical report

OSTI ID:5871325
A broad range of scientific investigations ranging from the development of large-scale models of ionospheric convection to small scale plasma flows associated with polar-cap arcs is described. It is shown that during times of northward IMF, coherent mesoscale convection features can frequently be identified at high latitudes. We now have the ability to quite accurately reproduce the convective features of the plasma at high latitudes during periods of southward IMF. Advances in understanding of electric-field coupling in plasma structures and the differences in local and height-integrated Joule heating rates are also described. The importance of the bottomside F-region concentration in determining the effectiveness of electrical coupling is emphasized.
