                         America (Gran Chaco) and southern Africa. Numerical experiments 
                         with different cumulus and solar radiation parameterization 
                         schemes were performed using a CPTEC Atmospheric global 
                         circulation model (CPTEC-AGCM) to study the impact of different 
                         physical processes on Southern Hemisphere summer climate. The 
                         CPTEC-AGCM in comparison with CPTEC/COLA-AGCM contains: a new 
                         dynamic code, three cumulus schemes (KUO, Relaxed 
                         Arakawa-Schubert, and Grell-ensemble modified by Figueroa, called 
                         here Grell2), two shallow convection schemes (Tiedke and Souza) 
                         and two solar radiation schemes (of Lacis and Hansen called here 
                         Rad1 and Clirad-sw of Chou and Suarez and modified by Tarasova and 
                         Fomin, called here Rad2). All remaining physical processes are 
                         similar to CPTEC/COLA AGCM. The horizontal resolution of the model 
                         is triangular 62 (T62), and vertical resolution is 28 levels 
                         (L28).The surface temperature is prescribed, which is updated 
                         daily by linear interpolation between monthly climatological 
                         blended data sets. The initial conditions were obtained from NCEP 
                         analysis. The integration is carried out for 5 years for each 
                         experiment. The results for different summers are similar. These 
                         results show the importance of convection scheme (deep and 
                         shallow) for tropical convection and subtropical convergence 
                         zones, and radiation scheme for subtropical low pressures. The 
                         main impact of Rad2 in comparison with rad1 is the reduction of 
                         downward solar radiation at the surface by approximately 50 W/m2 
                         in the subtropical region. Our conclusion is that the better 
                         simulation of Southern Hemisphere summer climate is by combination 
                         Grell2 for deep convection, Souza for shallow convection and Rad2 
                         for solar radiation.",
