Models of solar envelope have been computed with different values of Y, Z, and l/H (respectively abundances of helium and heavy elements and ratio of the mixing-length to the pressure scale height in the convective zone). These parameters are fitted so that the model gives the frequencies of solar oscillations observed by Grec et al. (1980) at the geographic south pole. It is found that the observations are compatible with the usually accepted solar abundances but they require a convective zone somewhat deeper than the one found in standard solar models.
