             abstract = "Relationships between simultaneous occurrences of distinctive 
                         atmospheric easterly wave (EW) signatures that cross the 
                         south-equatorial Atlantic, intense mesoscale convective systems 
                         (lifespan > 2 hour) that propagate westward over the western 
                         south-equatorial Atlantic, and subsequent strong rainfall episodes 
                         (anomaly > 10\ mm·day\−1) that occur in eastern 
                         Northeast Brazil (ENEB) are investigated. Using a simple 
                         diagnostic analysis, twelve cases with EW lifespan ranging between 
                         3 and 8 days and a mean velocity of 8\ m·s\−1 were 
                         selected and documented during each rainy season of 2004, 2005, 
                         and 2006. These cases, which represent 50% of the total number of 
                         strong rainfall episodes and 60% of the rainfall amount over the 
                         ENEB, were concomitant with an acceleration of the trade winds 
                         over the south-equatorial Atlantic, an excess of moisture 
                         transported westward from Africa to America, and a strengthening 
                         of the convective activity in the oceanic region close to Brazil. 
                         Most of these episodes occurred during positive sea surface 
                         temperature anomaly patterns over the entire south-equatorial 
                         Atlantic and low-frequency warm conditions within the oceanic 
                         mixing layer. A real-time monitoring and the simulation of this 
                         ocean-atmosphere relationship could help in forecasting such 
                         dramatic rainfall events.",
