  abstract = {{I}mpacts of the main {S}outh {A}merican orographic structures (the {A}ndes, the {B}razilian {P}lateau and the {G}uiana shield) on the regional climate and associated global teleconnection are investigated through numerical experiments in which some of these features are suppressed. {S}imulations are performed with a "two-way nesting" system coupling interactively the regional and global versions of the {LMDZ}4 atmospheric general circulation model. {A}t regional scale, the simulations confirm previous studies, showing that both the {A}ndes and the {B}razilian {P}lateau exert a control on the position and strength of the {S}outh {A}tlantic convergence zone ({SACZ}), mainly through their impact on the low-level jet and the coastal branch of the subtropical anticyclones. {T}he northern topography of {S}outh {A}merica appears to be crucial to determine the leading mode of rainfall variability in eastern {S}outh {A}merica, which manifests itself as a dipole-like pattern between {S}outheastern {S}outh {A}merica and the {SACZ} region. {T}he suppression of {S}outh {A}merica orography also shows global-scale effects, corresponding to an adjustment of the global circulation system. {C}hanges in atmospheric circulation and precipitation are found in remote areas on the globe, being the consequences of various teleconnection mechanisms. {W}hen the {B}razilian {P}lateau and the {A}ndes are suppressed, there is a decrease of precipitation in the {SACZ} region, associated with a weakening of the large-scale ascendance. {C}hanges are described in terms of anomalies in the {W}alker circulation, meridional displacements of the mid-latitude jet stream, {S}outhern annular mode anomalies and modifications of {R}ossby wave train teleconnection processes.},
