Mole, N., Kerekes, A. and Erdelyi, R. (2008) Effects of random flows on the solar f mode: I. horizontal flow. Solar Physics, 251 (1-2). pp. 453-468. ISSN 1573-093X
We examine the effect of random horizontal flows on the dispersion relation of high-degree solar f modes. We follow the approach of Murawski and Roberts (Astron. Astrophys. 272, 595, 1993), addressing some limitations of that paper, and extending the results to include damping and to apply for a general turbulent spectrum. We find a reduction in frequency below the classical result that is about three times that observed. For large wavenumber the damping rate is larger than the frequency correction by a factor of the order of the nondimensional wavenumber, which appears to be consistent with observation.
