Pierrehumbert, R. T. and Yang, H. 1993: Global chaotic mixing on isentropic surfaces.
If instead the vertical integral of the potential temperature is kept fixed — as argued by several authors to be appropriate in the case of convective mixing — an isentropic profile results.
With mixing comes an overall tendency toward an intermediate profile between isentropic and isothermal — no GHG's involved...
Radiative equilibrium does drive towards an isothermal state, but mixing goes towards an isentropic state, which is a recognized term indicating constant potential temperature (also dry adiabatic) because the log of potential temperature is basically the entropy in thermodynamic terms.
If you take an isothermal gas in gravity and thoroughly mix it, it turns isentropic.
