                         system is characterized by a pronounced dipole between 
                         southeastern South America and southeastern Brazil. Here we 
                         analyze the dynamical properties of extreme rainfall events 
                         associated with this dipole by combining a nonlinear 
                         synchronization measure with complex networks. We make the 
                         following main observations: (i) Our approach reveals the dominant 
                         synchronization pathways of extreme events for the two dipole 
                         phases, (ii) while extreme rainfall synchronization in the tropics 
                         is directly driven by the trade winds and their deflection by the 
                         Andes mountains, extreme rainfall propagation in the subtropics is 
                         mainly dictated by frontal systems, and (iii) the well-known 
                         rainfall dipole is, in fact, only the most prominent mode of an 
                         oscillatory pattern that extends over the entire continent. This 
                         provides further evidence that the influence of Rossby waves, 
                         which cause frontal systems over South America and impact 
                         large-scale circulation patterns, extends beyond the equator. Key
