Variations in the ionospheric Sq electric currents and fields caused by the changes in electric conductivity due to the solar activity variations are studied using the IRI model. Calculation is made for R = 35 and 200 on the assumption of constant (1, -2), (2, 2) and (2, 4) mode tidal winds. It is shown that the effect of semidiurnal tidal winds becomes strong and generates about one half of the total Sq currents in the ionosphere when solar activity is low. On the other hand, when solar activity is high, diurnal tidal winds become the main contributor to the Sq currents, although the inclusion of semidiurnal tidal winds creates a clockwise current vortex in the duskside low latitude region.
