“…Thus, the tropical Atlantic Ocean is often implicated in climate variability over parts of the adjacent continents including the Guinea coast, the Sahel, and Brazil Nordeste. Studies suggest that during the boreal summer [June-August (JJA)], tropical Atlantic variability is dominated by the equatorial zonal mode termed the Atlantic Niño occurring at the interannual time scale (Zebiak 1993;Chang et al 2006;Keenlyside and Latif 2007;Brandt et al 2011). The peak phase of the Atlantic Niño in JJA is characterized by a relaxation of the southeast trade winds and zonally oriented anomalous warming along the climatological mean axis of the cold tongue.…”

“…One, peaking in boreal spring, is the interhemispheric meridional sea surface temperature (SST) gradient linked to cross-equatorial winds referred to as the Atlantic meridional mode (Carton et al 1996;Chang et al 1997;Patricola et al 2014). Fluctuations in the meridional mode preceded Atlantic Niño during certain periods (Servain et al 1999), although the two are generally regarded as independent modes of variability.…”

“…This leads to weakening of the SE trades and intensification of the NE trades, with greater precipitation in tropical and subtropical South America. Such changes occur with mean periodicities of 10 to 14 years (Enfield and Mayer 1996;Chang et al 1997). In our study area, we would expect more rain during such minimum TAV years.…”

“…Of particular importance are decadal variations in the interhemispheric SST gradient across the Equator in the Atlantic, which is also called the Tropical Atlantic SST Variability (TAV) (Enfield and Mayer 1996;Chang et al 1997). When the cross-equatorial SST gradient is reduced, which corresponds to low TAV amplitudes, the tropical North Atlantic is cool relative to the South Atlantic, resulting in increased surface pressure over the North Atlantic and a southward shift of the ITCZ.…”

“…Eles sugeriram que as condições dinâmicas e termodinâmicas associadas ao dipolo meridional de ATSMs interferem sensivelmente modo envolve variações de TSM em ambos os hemisférios, em escalas de tempo sazonal, interanual e decadal (Servain, 1991). Chang et al (1997) atribuíram essa variabilidade a interações de calor induzidos pelo vento e TSM.…”
