  abstract = {{I}n the eastern {P}acific, lithogenic input to the ocean responds to variations in the atmospheric and oceanic system and their teleconnections over different timescales. {A}tmospheric (e.g., wind fields), hydrological (e.g., fresh water plumes) and oceanic (e.g., currents) conditions determine the transport mode and the amount of lithogenic material transported from the continent to the continental shelf. {H}ere, we present the grain size distribution of a composite record of two laminated sediment cores retrieved from the {P}eruvian continental shelf that record the last 1000 years at a sub-decadal to centennial time-series resolution. {W}e propose novel grain size indicators of wind intensity and fluvial input that allow reconstructing the oceanic atmospheric variability modulated by sub-decadal to centennial changes in climatic conditions. {F}our grain size modes were identified. {T}wo are linked to aeolian inputs ({M}3: similar to 54; {M}4: similar to 91 mu m on average), the third is interpreted as a marker of sediment discharge ({M}2: similar to 10 mu m on average), and the last is without an associated origin ({M}1: similar to 3 mu m). {T}he coarsest components ({M}3 and {M}4) dominated during the {M}edieval {C}limate {A}nomaly ({MCA}) and the {C}urrent {W}arm {P}eriod ({CWP}) periods, suggesting that aeolian transport increased as a consequence of surface wind stress intensification. {I}n contrast, {M}2 displays an opposite behavior, exhibiting an increase in fluvial terrigenous input during the {L}ittle {I}ce {A}ge ({LIA}) in response to more humid conditions associated with {E}l {N}ino-like conditions. {C}omparison with other {S}outh {A}merican paleoclimate records indicates that the observed changes are driven by interactions between meridional displacement of the {I}ntertropical {C}onvergence {Z}one ({ITCZ}), the {S}outh {P}acific {S}ubtropical {H}igh ({SPSH}) and {W}alker circulation at decadal and centennial timescales.},
