ABSTRACT
This chapter focuses on the troposphere and its quantitative modeling. The gross features of the atmospheric circulation are driven by convective currents due to differential heating, Earth rotation, and the asymmetric distribution of land and sea. Due to these factors, the atmosphere is divided into meridional and longitudinal convection cells. There exist various models for climate predictions in general and the computation of the mean temperature of the earth. The most sophisticated current models are the "Community Atmospheric Models" (CAM). The chapter provides a short narrative for Earth "climate modeling". A more detailed model for the albedo takes into account the different albedos of ocean, land, and ice and the meridional extent of the ice cover of the earth. The chapter expresses that due to the extreme complexity of the climate system, there remains a lot of uncertainty about our ability to predict the future climate of the earth.
