Tropical Atlantic Contributions to Strong Rainfall Variability Along the Northeast Brazilian Coast

Figure 6

Temporal evolution of the NEA (averaged over 40°–25°W and 0°–10°N) of SST and meridional PWS anomalies ((a) and (c)); MLD and BLT anomalies ((b) and (d)) from November-December (ND) to March-April (MA). ((a) and (b)) Composites are relative to 8 years of positive (>+0.5) normalized rainfall anomalies at Fortaleza (NNEB), and (c) and (d) composites are relative to 12 years of negative (<−0.5) normalized rainfall anomalies at Fortaleza (NNEB).
