Active-region Modulation of Subsurface Meridional Flows and Magnetic Flux Transport on the Sun
Anisha Sen, S. P. Rajaguru, Ruizhu Chen +2
Using time-distance helioseismology applied to 14-years of SDO/HMI observations spanning solar cycle 24 and rising phase of cycle 25, we present evidence that meridional flows in t…

Solar-cycle variations in meridional flows and rotational shear within the Sun's near-surface shear layer
Anisha Sen, S. P. Rajaguru, Abhinav Govindan Iyer +3
Using solar-cycle long helioseismic measurements of meridional and zonal flows in the near-surface shear layer (NSSL) of the Sun, we study their spatio-temporal variations and conn…

Hemispheric Magnetic Asymmetry and Cross-Equatorial Circulation Cells within the Sun's Near-Surface Shear Layer
Anisha Sen, S. P. Rajaguru, Ruizhu Chen +2
Using time-distance helioseismic measurements of meridional flow in the near-surface shear layer over a period of 14 years, starting from May 2010, we probe the depth structure and…
