             abstract = "The South Atlantic Convergence Zone (SACZ) , a cloudiness band 
                         oriented NW/SE over South America and South Atlantic which shows 
                         an interaction between tropical and middle latitudes systems is 
                         analysed in results of the Hadley Centre Model (HADAM2b). 
                         Outlongwave radiation (OLR) was analysed in 101 years of the model 
                         integration to identify extreme cases of convection associated 
                         with the SACZ. The extreme cases which occurred in December, 
                         January and February (DJF), during the whole analysed period, were 
                         averaged in 3 areas were the ZCAS can be located. The convective 
                         band was identified in the 3 areas, and the main characteristics 
                         were the presence of positive anomalies to the north and south of 
                         the band. The analyses of convective precipitation and specific 
                         humidity also show the same characteristics, indicating strong 
                         ascent of moist air in the region of the SACZ and subsidence and 
                         dry regions to the north and to the south. The area to the south 
                         has more intense positive anomalies of OLR and is drier than the 
                         area to the north. This feature can be associated with the 
                         displacement of zonal fronts which interact with the convection 
                         over the continent and which have to the rear, cold and dry air. 
                         Positive values of soil moisture in the region of the ZCAS can be 
                         a result of the intense precipitation and can also be seen as a 
                         feedback to the maintenance of the band.",
