[ 11 ] Whether an ion escaping the polar cap ionosphere at a certain latitude is directly lost downtail into the solar wind or fed to the plasma sheet (recirculated) is thus

If we assume that the entering high density plasma and the associated irregularities moved poleward into the polar cap along the convection streamlines, we can compare the

convection relative to the open/closed field line boundary for a B y dominated interplanetary magnetic field (IMF).. rate [Wb/s = V]) associated with the polar cap plasma circulation,
