             abstract = "The Atlantic Multidecadal Oscillation (AMO) is coherently linked 
                         to climate variations over many parts of the globe. Despite recent 
                         achievements, the mechanism by which the AMO influences regional 
                         precipitation over South America is not well understood. In this 
                         study, we isolate the atmospheric response to the AMO using a 
                         water isotope-enabled version of the Community Earth System Model 
                         version 1.2 (iCESM1.2) and determine its influence on 
                         (sub)tropical South American regional precipitation and 
                         atmospheric circulation. The results suggest an interhemispheric 
                         seesaw in Hadley circulation strength and that the section of the 
                         Atlantic Hadley cell is marked by a stronger upward air component 
                         south of the equator during the cold AMO phase. We also find that 
                         the precipitation anomalies over (sub)tropical South America 
                         during AMO phases are mainly related to changes in the Atlantic 
                         Intertropical Convergence Zone (ITCZ) core strength, where in the 
                         cold (warm) AMO phase the core region strengthens (weakens) from 
                         February to July, while from July to November the core region 
                         weakens (strengthens). Our results stress the importance of 
                         acknowledging the dynamics of season- and regional-dependent ITCZ 
                         responses, as they are sufficient to produce observed AMO-related 
                         signals even in the absence of marked changes in the ITCZ 
                         position.",
