A principal goal of the HMI investigation is to better characterize flows in the solar interior. Solar dynamics are a critical component of solar activity on both global scales and local scales. Of particular interest is the very difficult problem of finding the return flow (or flows) of meridional circulation. Other interesting areas of current research involve solar differential rotation, especially at high latitudes, and differences between the current solar cycle and previous ones; the characterization of the spectrum of velocities with depth; the characterization of local flow structures; and the calibration and improvement of far-side imaging techniques.
