In recent decades, there has been a divergence in the evidence (models, observations, reanalysis data) about the trend of coastal upwelling driving winds in the current global warming scenario over the Humboldt Current System. Herein, we present a 150 yr, sub-decadal grain size distribution record of a laminated sediment core (B0405-6) retrieved from the continental shelf of the Pisco region (∼14 °S) within the wind-driven coastal upwelling system of South-Central Peru. This area is characterized by local aeolian inputs from seasonal dust storms called Paracas Winds (PW). This study aims to reconstruct the variability of surface wind intensity using the Geometric Median Diameter (GMDs) and frequency (A%) of aeolian particles in a high temporal resolution sediment core and to unravel the mechanisms that control this variability. In addition, we propose to evaluate these GMDs as a better proxy of local surface wind strength and thus the variability of upwelling favorable winds (UFWs) in these near-source conditions. Our results show a progressive intensification of the UFWs in the region throughout the last 150 years, which agrees with other records along the South Pacific coast. In addition, good correspondence was found between the UFW wind proxy and the region's sea surface temperature (SST) trends, suggesting an intensification of the driving mechanisms linked to these events. It also suggests that UFW intensification could continue as the local coastal atmospheric jet strengthens. A comparison of indirect oceanic and atmospheric records from the South American Pacific coast is shown at the regional scale, suggesting a recent progressive expansion and intensification of the South Pacific Subtropical High (SPSH).
