Abstract
In Chaps. 3–5, it has been shown that the variability of precipitation in the Sahel region is linked to that of the SST at decadal-to-multidecadal time scales. The shifts of the Sahel precipitation regime during the late 20th century have been extensively studied due to its dramatic humanitarian and economic consequences such as during the 1970s and 1980s severe droughts. However, little is known about the decadal variability prior to the 20th century. Some evidences suggest that during the second half of the 19th century the Sahel was as much or even more rainy than during the 1950s and 1960s. The aim of this Chapter is to provide further evidences of such anomalous Sahel humid period in the late-19th century reproducing it by means of climate simulations, as well as to give an explanation to its origin.
