Fitting the results of linear normal-mode analysis of the solar five-minute oscillations to the observed k-ω diagram selects a class of models of the Sun's envelope. It is a property of all the models in this class that their convection zones are too deep to permit substantial transmission of internal g modes of degree 20 or more. This is in apparent conflict with Hill and Caudell's (1979) claim to have detected such modes in the photosphere. A proposal to resolve the conflict was made by Rosenwald and Hill (1980). They pointed out that nonlinear phenomena in the solar atmosphere might influence the eigenfrequencies considerably and suggested that a correct nonlinear analysis could predict a shallow convection zone. This paper is an enquiry into whether their hypothesis is plausible. It is concluded that the hypothesis of Rosenwald and Hill is unlikely to be correct.
