Abstract
A three layer model of the Sun is presented for the study of p-and f-modes. Frequency shifts due to the combined effects of an atmospheric magnetic field and subsurface equilibrium flows are evaluated by deriving and solving the dispersion relation. An increase in the chromospheric temperature can not only reduce but also raise the frequencies of p-and f-modes when a background magnetic field is present. Beside flow effects the effect of changing the height of the magnetic canopy is also examined. A comparison of our theoretical results with recent observational data shows an excellent agreement.
