We present a new concept to infer the meridional flow in the deep solar interior from global oscillation data. This concept is based on the estimation of the coupling strengths of p‐mode eigenfunctions mediated by the meridional flow. We illustrate the performance of the method using simulations and present first inversion results of a large‐scale flow component of the meridional flow obtained from MDI data (© 2012 WILEY‐VCH Verlag GmbH & Co.
