Helioseismology uses sound waves propagating in the Sun to probe its interior structure and dynamics.
On the global scale and on timescales of years, we can study the variation of zonal and meridional flow patterns with the solar cycle. The zonal flow pattern in the current extended solar minimum, for example, shows slower migration towards the equator than that seen in the previous minimum.
We will report on the most recent and relevant results.
