                         region have registered very severe droughts during the last two 
                         decades, with a frequency that may have exceeded natural climate 
                         variability. Severe droughts impact the physiological response of 
                         Amazon forests, decreasing the availability to absorb atmospheric 
                         CO2, as well as biodiversity and increasing risk of fires. 
                         Droughts on this region also affect population by isolating them 
                         due to anomalous low river levels. Impacts of droughts over NEB 
                         region are related to water and energy security and subsistence 
                         agriculture. Most drought episodes over Amazonia and NEB are 
                         associated with El Niņo (EN) events, anomalous warming over the 
                         Tropical North Atlantic (TNA), and even an overlapping among them. 
                         However, not all the dry episodes showed a large-scale pattern 
                         linked to a canonical EN event or warm TNA episodes. For instance, 
                         dry episodes linked to EN events present distinct spatial patterns 
                         of precipitation anomalies depending on EN type (Central-Pacific 
                         vs. Eastern-Pacific EN), and NEB region experienced a severe 
                         drought in 2012 that is not attributed to EN or warm TNA events. 
                         Even in the case of the strong EN in 2015/16, some regional 
                         impacts have not been explained by EN contribution. This paper 
                         discusses the effects of CP and EP EN events, and the role of warm 
                         TNA events on tropical Walker and Hadley circulation leading to 
                         drought over Amazonia and NEB regions.",
