Abstract

Entropy production has been calculated as a function of the coefficient of meridional heat transfer for two seasonal energy-balance climate models. Both models display extrema in entropy production at values of the coefficient appropriate to the present climate. Inclusion of time dependence in the models is found to be the essential feature for successful application of entropy extremization.
