On the basis of Paltridge's 'minimum entropy exchange' principle, a new concept-entropic energy function-is presented in this paper. Most of the parameters used in Paltridge's model are induced, but some of them are revised in order to make their physical meanings much clearer. With a constraint of minimizing the 'entropic energy function', we have obtained a zonal average distribution of surface temperature T, cloudness θ and meridional flux of energy, which is coincided with the observations. Sen-sitivity experiment shows that if the content of CO2 in the atmosphere is doubled,the surface temperature would be 0.8°K higher.It is in agreement with some of the energy balance models.
