%X At this work is introduced a parameterization of radiative process in a simple climatic model, wich consider the mean zonal atmosphere. This model is hemispheric, quasi-geostrophic, and had a simple radiation parameterization. The new parameterization introduced in the model is more sofisticated than the old one and is more versatile relative to perform of sensitivity experiments. In the parameterization of solar radiation the characteristics of atmosphere, like reflexivity, absorvitivity and transmitivity depend of contribution related to the atmosphere without clouds and covered. In the parameterization of long wave radiation, is considered the effect of gas with greather absorption: CO2 and water vapour. The resulted show that the radiative fluxes are generally better simulated in regard to before parameterization and that the zonal averaged characteristics of atmosphere are correctaly simulated by the model.
