  abstract = {{M}esoscale sea surface temperature ({SST}) variability plays an important role in shaping local atmospheric boundary layers through thermodynamic processes. {T}his study focuses on the upscaling effects of mesoscale {SST} gradients in sensitive areas on the southern {A}frica regional atmospheric circulation. {U}sing regional atmospheric model sensitivity experiments which differ only in the mesoscale {SST} forcing characteristics (either the full spectrum of {SST} variability or only its large-scale components are included), we first quantify the importance of {SST} gradients on regional atmospheric conditions. {A}gulhas eddies and meanders influence the vertical air column up to the troposphere, and mesoscale ocean patterns significantly modify incoming landwards moisture fluxes. {T}he austral summer mean state is then modified in terms of air temperature, cloud cover and mean rainfall, with notable differences in tropical rainbands over southwestern {A}frica. {M}esoscale {SST} variability favours tropical-extra-tropical interactions and cloudband development over the continent. {T}hese results stress the importance of high-resolution ocean forcing for accurate atmospheric simulations.},
