AB: Migrating bands of weak zonal flow, associated with the activity bands in the solar cycle, have been observed at the solar surface for some time. More recently, these flows have been probed deep within the convection zone using global helioseismology, and examined in more detail close to the surface with the techniques of local helioseismology. We compare the results from global and local helioseismology using data from the Michelson Doppler Imager and the GONG network and also Doppler measurements from Mount Wilson, and find that the results are in reasonable agreement, with some explicable differences in detail. This was work was supported by the National Science Foundation and NASA.
