                         in has been well established over some regions of South America, 
                         primarily in the northern sector and in northern Argentina, 
                         Southern Brazil. However the sea surface temperature (SST) impact 
                         on the South Atlantic Zone Convergence (SACZ) is not fully 
                         understood. With the objective of better understanding the 
                         ocean-atmosphere interaction and the SACZ, the relation between 
                         sea surface temperature (SST) and precipitation on the South 
                         America for the austral summer was evaluated. The analysis 
                         technique is based on Singular Value Decomposition of the monthly 
                         precipitation data (Global Precipitation Climatology Project) on 
                         South America (40°S the 0 and 65°W 30°W) and SST of the Atlantic 
                         (40°S 20°N and 60°W 15°E) and Pacific Oceans (40°S 20°N and 140°E 
                         90°W) separately. This technique was applied to the 
                         December-January-February period from 1981 to 2004, and for three 
                         lags ( 1 to 3 months) between precipitation and SST, with the SST 
                         lagged with relation to precipitation. The first mode for the 
                         Atlantic Ocean, indicates that when the SACZ is displaced to the 
                         south (north), the warm (cold) SST is verified in the south 
                         tropical Atlantic and cold (warm) to the south of the analyzed 
                         domain (from 30°S). For the lagged SST, the north-south 
                         displacement of the SACZ is mainly related to the tropical SST. 
                         For the second mode, the precipitation field is associated to the 
                         SACZ intensity, and the region with stonger SST influence is in 
                         the tropical south Atlantic. This coupling indicates that increase 
                         of precipitation is associated with the warm SST anomalies in the 
                         tropical South Atlantic and a similar pattern is verified for all 
                         lags. For the Pacific Ocean, the same spatial structure of the 
                         modes are observed in all lags. The precipitation pattern in the 
                         first mode is similar to the first mode of the Atlantic Ocean 
                         (dipole) and it indicates that the SACZ displaced to the south 
                         (north) is associated with the El Niño (La Niña) event. The second 
                         mode is associated to increase of the precipitation on the SACZ 
                         and warm SST anomalies the East Pacific and to the cold anomalies 
                         in the West Pacific.",
