Scientific paper

Howe et al. (2009) demonstrate that solar activity appears to move towards the equator somewhat parallel to the latitude motion of torsional oscillation flows. However, Snodgrass (1987) had previously suggested that the regions between the fast and slow torsional oscillation flows represent zones where magnetic field is concentrated, which results in the formation of activity. In an attempt to test this suggestion, Altrock et al. (2008) compared the location of bright Fe XIV coronal regions to the latitude derivative of torsional oscillation frequencies and found that the bright regions occurred over regions where the latitude derivative was at its lowest (negative) value; i.e., between the fast and slow streams, thus verifying Snodgrass' suggestion. This paper extends and verifies the results of Altrock et al., that SOLAR ACTIVITY OCCURS OVER THE ``SHEAR'' ZONE BETWEEN FAST AND SLOW TORSIONAL OSCILLATION FLOWS.
