Effect of longitudinal electrical resistance on magnetospheric-ionospheric convection
Abstract
The influence of longitudinal resistance on magnetospheric-ionospheric convection is investigated theoretically with allowance for the spread-out character of the inner boundary of the plasma sheet. The electric field potential experiences a discontinuity at the boundary of the polar cap in the magnetosphere. Inside the polar cap at ionospheric heights, the potential distribution becomes asymmetric with respect to the day-night meridian and closed convective vortices appear. The convective tongue in the ionosphere becomes even more pronounced.
