             abstract = "This work aims at studying the relationship between tropical 
                         Atlantic latent heat flux and convective cloud coverage over the 
                         Northeast of Brazil (NEB) during the four months of the main rainy 
                         season (February to May) in this region. The correlation with the 
                         anomalies of these data is investigated, without lag and with 
                         one-month lag (the heat flux in advance). In both cases, a 
                         significant positive correlation appears in the Northern Western 
                         Tropical Atlantic, and a significant negative correlation is 
                         obtained for a limited area off eastern NEB. These two correlation 
                         patterns are linked to anomalies in the trade wind intensity and 
                         in the meridional position of the inter-tropical convergence zone 
                         (ITCZ), that respectively relate to the latent heat flux anomalies 
                         and NEB convective coverage anomalies. The patterns obtained here 
                         show that the Northern Tropical Atlantic has a predominant 
                         influence on NEB, and that the key-region of the Southern Tropical 
                         Atlantic is only located around the NEB eastern coast. The impact 
                         of the Atlantic heat fluxes on the NEB convection is somewhat 
                         different of the classical meridional dipole related to the SST 
                         variability. The analysis of the horizontal moisture flux shows 
                         that during flood years an additional meridional inflow balances 
                         the eastward loss, and the upward velocity reinforced over NEB 
                         contributes to intensify NEB convection. The positive correlation 
                         pattern indicates that the location of the northern branch of the 
                         PIRATA (Pilot Research moored Array in the Tropical Atlantic) 
                         moorings is pertinent to monitor the ocean-atmosphere interface 
                         parameters. The negative correlation pattern off NEB provides new 
                         argumentation in the design of the possible extension of the 
                         PIRATA array towards the Brazilian coast. Complementary results at 
                         one-month lag and the real-time availability of the PIRATA data 
                         confirm the potentiality of NEB forecasting.",
