The currents at the ionosphere also show these features. Figures 6a and 6b show the field-aligned current in the northern ionosphere for the two cases, while Figures 6c and 6d show the corresponding currents in the southern ionosphere. Note that positive (red) field-aligned currents in both hemispheres are northward along the field line, so upward current in the southern hemisphere is red. The strongest currents in both hemispheres are associated with the RAW and MAW; however, there are weaker currents associated with the secondary waves. The currents are somewhat weaker than when Io is near the equator, and they are weaker in the southern hemisphere than in the north. As in the previous runs, the U shape of the main spot is due to the changing cross section of Io and its ionosphere as it crosses field lines; this structure is maintained in the reflected waves. This pattern is more distinct in the northern hemisphere currents, suggesting that the pattern is washed out to some degree passing through the plasma torus. In the northern hemisphere, the current pattern is similar to the symmetric case with the upward field-aligned current occurring at the lower L-shells; however, in the southern hemisphere the MAW and RAW spots are closer together with significant currents between them.
