Short summary

Wind variability drives coherent variability in surface temperature, salinity, and sea level across the Patagonian shelves of South America. Our findings suggest that southerly winds enhance Pacific coastal upwelling, export fresh waters offshore, weaken the Cape Horn Current, and strengthen northward transport of cold, salty subantarctic waters over the Atlantic shelf, while northerly winds reverse these patterns, revealing wind-driven modulation of shelf circulation and interocean exchanges.
