  abstract = {{P}recipitation regime shifts in the {S}ahel region have dramatic humanitarian and economic consequences such as the severe droughts during the 1970s and 1980s. {T}hough {S}ahel precipitation changes during the late twentieth century have been extensively studied, little is known about the decadal variability prior to the twentieth century. {S}ome evidence suggests that during the second half of the nineteenth century, the {S}ahel was as rainy as or even more rainy than during the 1950s and 1960s. {H}ere, we reproduce such an anomalous {S}ahel humid period in the late nineteenth century by means of climate simulations. {W}e show that this increase of rainfall was associated with an anomalous supply of humidity and higher-than-normal deep convection in the mid- and high troposphere. {W}e present evidence suggesting that sea surface temperatures ({SST}s) in the {A}tlantic basin played the dominant role in driving decadal {S}ahel rainfall variability during this early period.},
