I agree with Holtm that further studies incorporating synoptic-cumulus scale interactions as well as boundary layer friction are necessary. In particular, the last two terms in eq. 5 of Shapiro (1977) can not balance with an inviscid interior (Stevens et al. (1976)). The tendency of these terms to balance can be attributed to the inclusion of cumulus momentum transports and can not be specified a priori without omitting essential physics. Thus a barotropic model, such as Holton’s (1979, which can not incorporate the vertical structure of the heating or the waves and which allows only a Rayleigh friction form of cumulus momentum transports (Holton’s eq. 14), can not properly diagnose the dynamics of the waves above the boundary layer.DOI: 10.1111/j.2153-3490.1977.tb00739.x
