  abstract = {{T}he influence of soil moisture initial conditions on the climate extreme indices over {W}est {A}frica was investigated using the fourth generation of the {I}nternational {C}entre for {T}heoretical {P}hysics regional climate model (non-hydrostatic) coupled with version 4.5 of the {C}ommunity {L}and {M}odel ({R}eg{CM}4-{CLM}4.5) at a 25 km spatial resolution. {W}e initialized the control experiments with the reanalysis soil moisture data from the {E}uropean {C}entre for {M}edium-{R}ange {W}eather {F}orecasts ({ECMWF}) reanalysis of the 20th century ({ERA}-20{C}), while we initialized the dry and wet experiments with the maximum and minimum soil moisture values over the {W}est {A}frica domain, respectively. {F}or each experiment, an ensemble of five runs was performed for 5 years (2001-2005) with soil moisture initial conditions for the runs prescribed on 1 {J}une and the simulations being performed over 4 months (122 d) from {J}une to {S}eptember. {T}he performance of {R}eg{CM}4-{CLM}4.5 with respect to simulating the 10 extreme rainfall and temperature indices used in this study is presented. {T}he results are then discussed for the two idealized simulations that are most sensitive to the dry and wet soil moisture initial conditions in order to highlight the impacts beyond the limits of soil moisture internal forcing in the model. {O}ver the {C}entral {S}ahel, dry (wet) experiments lead to a decrease (increase) in precipitation extreme indices related to the number of events, but this was not seen for indices related to the intensity of the events. {S}oil moisture initial conditions unequally affect the daily minimum and maximum temperatures. {T}he strongest impact is found on the maximum temperature: wet (dry) experiments decrease (increase) the maximum temperature over the whole region. {O}ver the {C}entral {S}ahel, wet (dry) experiments lead to a decrease (increase) in the maximum values of the minimum temperature.},
