WebDec 1, 2011 · The magnetosphere and ionosphere are coupled into a power circuit by field-aligned currents. If there were only Hall current in the ionosphere, the problem of magnetosphere-ionosphere interaction ... WebJun 21, 2011 · The second step involves the interaction of the electric field of the MS wave with the Hall conductivity of the lower ionosphere. The Hall current, driven by the electric field of the MS wave generates ground magnetic field signatures and drives Shear Alfven (SA) waves upwards along the magnetic tube that intersects the interaction region, in a ...

WebA common measure for the quiet time ionosphere are median values of the ionosphere during one solar rotation period (27 days). The deviation of the ionosphere from the quiet values (median) are considered as ionospheric perturbations. The service provides a map of Europe presenting the current level of ionospheric activity (perturbations of foF2). WebThe following five points are described in detail for the global scale distribution of the Pedersen and the Hall current: (1) the Pedersen current, (2) the magnetospheric plasma, (3) the primary Pedersen current, (4) the Hall current, and (5) the divergence of J sub H.
