导出了太阳p模和f模振荡本征函数中由于赤道对称的大尺度经向流引起的扰动的近似表达式。导出了全球日震资料中摄动特征函数的基本特征,并讨论了利用全球地震技术探测子午流的前景。
Approximate expressions are derived for the perturbations in solar p- and f-mode oscillation eigenfunctions, due to large-scale, meridional flows which are symmetric about the equator. The essential signature of the perturbed eigenfunctions in global helioseismic data is derived and the prospects for detecting meridional flow using global seismic techniques are discussed.
