Asymmetry in Solar Torsional Oscillation and the Sunspot Cycle
Asymmetry in Solar Torsional Oscillation and the Sunspot Cycle
Solar torsional oscillations are migrating bands of slower- and faster-than-average rotation, which are strongly related to the Sun's magnetic cycle. We perform a long-term study (16 yr) of hemispherical asymmetry in solar torsional oscillation velocity using helioseismic data for the first time. We study the north-south asymmetry in the velocity …
