Some drought years over sub-Saharan west Africa (1972, 1977, 1984) have been previously related to a cross-equatorial Atlantic gradient pattern with anomalously warm sea surface temperatures (SSTs) south of 10 N and anomalously cold SSTs north of 10 N. This SST dipolelike pattern was not characteristic of 1983, the third driest summer of the twentieth century in the Sahel. This study presents e...
