  abstract = {{T}his study uses the high-resolution outputs of the recent {CORDEX}-{A}frica climate projections to investigate the future changes in different aspects of the hydrological cycle over {W}est {A}frica. {O}ver the twenty-first century, temperatures in {W}est {A}frica are expected to increase at a faster rate (+0.5 degrees {C} per decade) than the global average (+0.3 degrees {C} per decade), and mean precipitation is expected to increase over the {G}uinea {C}oast (+0.03 mm d(-1) per decade) but decrease over the {S}ahel (-0.005 mm d(-1) per decade). {I}n addition, precipitation is expected to become more intense (+0.2 mm d(-1) per decade) and less frequent (-1.5 d per decade) over all of {W}est {A}frica as a result of increasing regional temperature (precipitation intensity increases on average by +0.35 mm d(-1) degrees {C}-1 and precipitation frequency decreases on average by -2.2 d degrees {C} -1). {O}ver the {S}ahel, the average length of dry spells is also expected to increase with temperature (+4 % d degrees {C}-1), which increases the likelihood for droughts with warming in this subregion. {H}ence, the hydrological cycle is expected to increase throughout the twenty-first century over all of {W}est {A}frica, on average by +11 % degrees {C}-1 over the {S}ahel as a result of increasing precipitation intensity and lengthening of dry spells, and on average by +3 % degrees {C}-1 over the {G}uinea {C}oast as a result of increasing precipitation intensity only.},
