  abstract = {{P}recipitation regime shifts in the {S}ahel have dramatic humanitarian and economic consequences such as during the 1970's and 1980's severe droughts. {T}hough {S}ahel precipitation changes during the late 20th century have been extensively studied, little is known about the decadal variability prior to the 20th century. {S}ome evidences suggest that during the second half of the 19th century the {S}ahel was as much or even more rainy than during the 1950's and 1960's. {H}ere, we reproduce such anomalous {S}ahel humid period in the late-19th 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 middle and high troposphere. {W}e present evidence suggesting that {S}ea {S}urface {T}emperatures ({SST}s) in the {A}tlantic basin played the dominant role in driving decadal {S}ahel rainfall variability in this early period.},
