<p>The Antarctic Slope Current (ASC) links the processes occurring in the coast area with the global ocean by modulating the flow across the continental slope, which influences global overturning circulation and the mass balance of the Antarctic ice shelves. This paper aims to explore the effects of wind and buoyancy fluxes on the long-term changes in the ASC using observation and reanalysis datasets. From 1993 to 2022, the ASC accelerated in all seasons, particularly in austral autumn, and was accompanied with the advancement of the strong flow. The positive buoyancy flux anomaly generates a low-density anomaly, which is accumulated by the prevailing surface easterly, maintaining a sharp density front along the continental slope. The heat flux intensifies the positive trend of buoyancy flux in summer and autumn, increasing the input of the lighter density anomaly into the ocean and advancing the strong flow of ASC. Compared with the annual mean, the additional acceleration of the ASC in autumn is mainly due to the contribution of the barotropic component, which could be explained by the local momentum input from the weakly enhanced local surface wind. The acceleration of the ASC is primarily driven by the positive trend of the buoyancy flux, while the influence of the wind on its seasonal variability becomes more significant due to the contribution of the local surface wind in autumn.</p>
