Entropy in Climate Models. Part I: Vertical Structure of Atmospheric Entropy Production

Abstract

The vertical atmospheric entropy structure has been investigated using one-dimensional radiative-convective models. A method for evaluating radiation entropy is proposed. In the models, the entropy radiation is dealt with m a w~y parallel to the energy _radiation. The profiles of the radiative entropy fluxes, the vertical distributions of the mtemal entropy production rates of the atmosphere in different seasons, and the entropy budget for a column atmosphe_re are obtamed. The mfluence of clouds and the possible change of atmospheric constituents on the atmosphenc entropy structure are also discussed.
