Dynamics of Active Regions Revealed by Tracking of Doppler Features
Original language description
We investigate the large-scale horizontal dynamics of active regions in the 23rd solar cycle. The large-scale horizontal velocity fields were measured applying the local correlation tracking (LCT) algorithm to the processed high-cadence full-resolution full-disc MDI Dopplergrams. We performed the selection of NOAA active regions in the available dataset and followed their individual evolution in time. The statistical study of this sample gives us a unique opportunity to study the dynamics of active regions at various stages of their evolution. In few cases, we found behavior that is consistent with the dynamical disconnection of sunspots from the magnetic roots.
