Rainfall time series between 1964–2015 at latitudes 9°, 12° and 13° South encompass the cities of Paulo Afonso-BA, Sobradinho-BA, Bom Jesus da Lapa-BA and Irecê-BA, indicating a decreasing trend in precipitation by the Student t-test.
Thus, there is an increasing trend in sea surface temperatures over the Tropical Atlantic shifting the ITCZ northward, reducing rainfall south of the Equator [ 27 ].
