  abstract = {{A} relationship between oceanic conditions in the northwestern equatorial {A}tlantic ({NWEA}) and the seasonal rainfall over the northern part of {B}razilian {N}ortheast ({NNEB}) allows large climate events to be forecasted with a delay of a few months. {O}bserved sea surface variables (sea surface temperature, wind stress and latent heat flux) and reanalyzed temperature and salinity profiles at depths of 0 - 150 m are used during 1974-2008. {P}erturbations in the {W}ind-{E}vaporation-{SST} mechanism over the {NWEA} during the last months of the year and the first months of the following year are of primary importance in evaluating the risk that strong climate events will affect the subsequent seasonal rainfall (in {M}arch-{A}pril) over the {NNEB}. {E}specially interesting are the {B}arrier {L}ayer {T}hickness ({BLT}) and {O}cean {H}eat {C}ontent ({OHC}) in the {NWEA} region from {A}ugust-{S}eptember through the subsequent months, during which a slow and steady evolution is apparent, with the highest signal occurring in {O}ctober-{N}ovember. {T}hrough their relationship with the local surface dynamic conditions, such {BLT} and {OHC} perturbations during the last months of the year can be used as a valuable indicator for forecasting wet or dry events over the {NNEB} during the subsequent rainfall season. {A} proposal is discussed to deploy additional temperature/conductivity sensors down to a depth of 140 m at three {PIRATA} moorings located in the {NWEA} region. {T}hat will be necessary if the {BLT} and other parameters of energy exchange between the ocean and atmosphere are to be estimated in real time and with a sufficiently high vertical resolution.},
