                         frontogenetic and frontolytic effects of the horizontal 
                         deformation and divergence fields in the lower troposphere over 
                         the part of the globe enclosed between 45N and 45S is made. The 
                         well-known frontogenetic regions of the Northern Hemisphere off 
                         the Rockies and the Japan Sea area are reproduced satisfactorily. 
                         Four bands of frontogenesis, aligned northwest to southeast, are 
                         clearly seen, and one of them agrees closely with the South 
                         Pacific Convergence Zone. The frontogenetic funtion over the 
                         central. and southern Argentina is strongest in sumner (January), 
                         which is in contrast to the Northern Hemispheric situation. Over 
                         South America, a northwest to southeast oriented line passing 
                         through the State of Rio de Janeiro divides the regions of 
                         frontogenesis to the southwest and frontolysis to the northeast. A 
                         case study of frontogenesis which occurred in the period 28-31 
                         July 1980 over South Brazil is presented. It shows clearly the 
                         importance of the horizontal deformation field in the formation, 
                         intensification, orientation and movement of the front. In the 
                         formative stage, strong warm advection ahead of the front-is 
                         observed in the lower middle troposphere and strong cold advection 
                         behind the front in the surface layers. In the mature stage the 
                         front presents all the characteristics observed by Sanders.",
