                         South America (SA) is examined using the surface air temperature 
                         (T-air) of Punta Arenas, Chile (53.0 degrees S, 70.85 degrees W), 
                         during the 1888-2016 period. The T-air shows multidecadal 
                         oscillations with a significant positive correlation of 0.77 to 
                         the AMO index. The relations of the Punta Arenas T-air time series 
                         with the AMO-related global sea surface temperature (SST) and 
                         regional circulation anomaly patterns are discussed. During the 
                         warm (cold) AMO phase, a cold (warm) center in southwestern 
                         Atlantic waters induces low-level anticyclonic (cyclonic) 
                         anomalies in the region, which together with the cyclonic 
                         (anticyclonic) anomalies in the southeastern Pacific channel the 
                         northerly (southerly) flow over southern SA. This meridional flow 
                         transports warm (cold) air from lower (higher) latitudes into the 
                         Punta Arenas region. Therefore, the temperature horizontal 
                         advection at the low level is the main thermodynamic process that 
                         alters the Punta Arenas T-air in a multidecadal time scale. The 
                         use of a relation between a long T-air surface sensor series in 
                         southern SA with the AMO presents a novel approach in climate 
                         monitoring and modeling.",
