                         University of Wisconsin -Milwaukee/Comprehensive Ocean-Atmosphere 
                         Data Set) dataset (1950-1993), and of NCEP/NCAR reanalysis and 
                         satellite-based QuikSCAT dataset (2000-2006), is made over the 
                         South Atlantic (10 degrees N-40 degrees S). On a mean seasonal 
                         scale, the comparison shows that these three wind stress datasets 
                         have qualitatively similar patterns. Quantitatively, in general, 
                         from about the equator to 20 degrees S in the mid-Atlantic the 
                         wind stress values are stronger in NCEP/NCAR data than those in 
                         UWM/COADS data. On the other hand, in the Intertropical 
                         Convergence Zone (ITCZ) area the wind stress values in NCEP/NCAR 
                         data are slightly weaker than those in UWM/COADS data. In the 
                         South Atlantic, between 20 degrees S-40 degrees S, the QuikSCAT 
                         dataset presents complex circulation structures which are not 
                         present in NCEP/NCAR and UWM/COADS data. The wind stress is used 
                         in a numerical ocean model to simulate ocean currents, which are 
                         compared to a drifting-buoy observed climatology. The modeled 
                         South Equatorial Current agrees better with observations between 
                         March-May and June-August. Between December-February, the South 
                         Equatorial Current from UWM/COADS and QuikSCAT experiments is 
                         stronger and more developed than that from NCEP/NCAR experiment. 
                         The Brazil Current, in turn, is better represented in the QuikSCAT 
                         experiment. Comparison of the annual migration of ITCZ at 20 
                         degrees and 30 degrees W in UWM/COADS and NCEP/NCAR data sources 
                         show that the southernmost position of ITCZ at 30 degrees W in 
                         February, March and April coincides with the rainy season in NE 
                         Brazil, while the northernmost position of ITCZ at 20 degrees W in 
                         August coincides with the maximum rainfall of Northwest Africa.",
