The effects of two different evaporation parameterizations on the climate sensitivity to solar constant variations are investigated by using a zonally averaged climate model. The model is based on a two-level quasi-geostrophic zonally averaged annual mean model. One of the evaporation parameterizations tested is a nonlinear formulation with the Bowen ratio determined by the predicted vertical temperature and humidity gradients near the earth's surface. The other is the linear formulation with the Bowen ratio essentially determined by the prescribed linear coefficient.read more

On the simulation of the axisymmetric circulation of the atmosphere : technical report
P Fuenzalida,Humberto +1 more
TL;DR: In this paper, the effects of the eddies on the zonal state are parameterized in terms of exchange coefficients which vary with latitude and time in the most general model, and the results show that a considerably improved simulation of the zonally-averaged state is obtained by a better parameterization of the processes entering the heat budget as compared with earlier studies.

A parameterization for the absorption of solar radiation in the earth's atmosphere
Andrew A. Lacis,James Hansen +1 more
TL;DR: In this article, a method is described for rapidly computing the amount of solar energy absorbed at the earth's surface and in the atmosphere as a function of altitude, which is a parametric treatment, but the form of the solution and coefficients involved are based on accurate multiple-scattering computations.

The effect of solar radiation variations on the climate of the Earth
TL;DR: In this article, the influence of long-term changes of radiation caused by variations of atmospheric transparency on the thermal regime is studied, and it is found that comparatively small variations in atmospheric transparency could be sufficient for the development of quaternary glaciations.

Transfer properties of the large-scale eddies and the general circulation of the atmosphere
TL;DR: In this article, the transfer of heat and momentum by motion on the scale of cyclone waves and long waves is deduced from a knowledge of their mechanics, which is independent of notions of mixing but is similar to that for non-isotropic diffusion.

Climate Change: An Appraisal of Atmospheric Feedback Mechanisms Employing Zonal Climatology.
TL;DR: In this paper, the sensitivity of the earth's surface temperature to factors which can induce long-term climate change, such as a variation in solar constant, is estimated by employing two readily observable climate changes.

The Effects of Changing the Solar Constant on the Climate of a General Circulation Model
TL;DR: In this article, the authors evaluate the response of a simplified three-dimensional model climate to changes of the solar constant and find that the temperature of the model troposphere increases with increasing solar radiation, and the greatest increase occurs in the surface layer of higher latitudes due to the effects of the snow-cover feedback mechanism as well as the suppression of vertical mixing by a stable lower troposphere.
