                         Brazil-Malvinas Confluence (BMC) were investigated through wavelet 
                         analysis and numerical modeling. Wavelet analysis was applied to 
                         recognize the main spectral signals of SST anomaly events in the 
                         BMC and in the Drake Passage as a first attempt to link middle and 
                         high latitudes. The numerical modeling approach was used to 
                         clarify the local oceanic dynamics that drive these anomalies. 
                         Wavelet analysis pointed to the 8-12-year band as the most 
                         energetic band representing remote forcing between high to middle 
                         latitudes. Other frequencies observed in the BMC wavelet analysis 
                         indicate that part of its variability could also be forced by 
                         low-latitude events, such as El Nio. Numerical experiments carried 
                         out for the years of 1964 and 1992 (cold and warm El Nio-Southern 
                         Oscillation (ENSO) phases) revealed two distinct behaviors that 
                         produced negative and positive sea surface temperature anomalies 
                         on the BMC region. The first behavior is caused by northward cold 
                         flow, Rio de la Plata runoff, and upwelling processes. The second 
                         behavior is driven by a southward excursion of the Brazil Current 
                         (BC) front, alterations in Rio de la Plata discharge rates, and 
                         most likely by air-sea interactions. Both episodes are 
                         characterized by uncoupled behavior between the surface and deeper 
                         layers.",
