                         climate-sensitive sectors of society, such as the economy and 
                         environment, with signifi cant impacts on water, energy, 
                         agriculture and fi sheries. This is the case in South America, 
                         whose economy is highly dependent on the agricultural sector. 
                         Here, we analyzed the sensitivity of South American climate to 
                         positive extremes of Antarctic sea ice (ASI) extent and volume at 
                         continental and regional scales. Sensitivity ensemble experiments 
                         were conducted with the GFDL-CM2.1 model and compared with the 
                         ERA-Interim reanalysis dataset. The results have shown signifi 
                         cant impacts on the seasonal regime of precipitation, air 
                         temperature and humidity in South America, such as a gradual 
                         establishment of the South Atlantic Convergence Zone, the 
                         formation of the Upper Tropospheric Cyclonic Vortex, the 
                         strengthening of Bolivian High and the presence of a low level 
                         cyclonic circulation anomaly over the South Atlantic Subtropical 
                         High region which contributed, for instance, to increased 
                         precipitation over the Southeastern Brazil. A northward shift of 
                         the Intertropical Convergence Zone was initially also a response 
                         pattern to the increased ASI. Moreover, the greatest variance of 
                         the climatic signal generated from the disturbances applied on the 
                         high southern latitudes has occurred in the interseasonal 
                         timescale (110120 days), especially over the Brazilian Amazon and 
                         the Southeastern Brazil regions.",
