                         (Atlantic Meridional Mode-AMM), subtropical (South Atlantic 
                         Subtropical Gradient-SASG), and extratropical (Southern Annular 
                         Mode-SAM) teleconnection patterns, the Weddell Sea (WS) sea ice 
                         extents, and the climate in South America. Warm anomalies are 
                         observed in most of South America for maximum WS ice extent 
                         combinations (negative SAM/positive AMM and negative SAM/positive 
                         SASG composites), with an opposite signal at tropical South 
                         America for minimum WS ice extent combinations (positive 
                         SAM/negative AMM and positive SAM/negative SASG). Over Southern 
                         Argentina, colder (warmer) temperatures are seen at the negative 
                         SAM/positive SASG (positive SAM/negative SASG). Drier (wetter) 
                         conditions are found over most South America at maximum (minimum) 
                         WS ice extent combinations. Wavetrains from different Pacific and 
                         Indian Oceans regions are related to high-level anomalous cyclonic 
                         (anticyclonic) circulation over the continent at maximum (minimum) 
                         WS ice extent configuration, which explains the climate impacts 
                         found. The SASG signal displaces the anomaly circulations eastward 
                         from South America, impacting the adjacent Atlantic Ocean region 
                         more intensely concerning the other modes. The results discussed 
                         here indicated that these patterns (SAM, AMM, SASG, and sea ice 
                         extent) have significant links with the South American climate 
                         variability.",
