Description
Using the helioseismic data for the last nearly 30 years from GONG, MDI and HMI instruments it is possible to study the solar cycle variations in structure and dynamics. Variations in frequencies are found to be correlated to solar activity and the inversion of these frequency differences, shows that the variation is confined to near surface region and is generally attributed to variation in the solar magnetic field. The solar rotation shows a distinct pattern of variation with solar cycle and this is referred to as the zonal flows. These results will be discussed.
