This study investigated the impact of direct aerosol feedback (DAF) on meteorology and particulate matter (PM<sub>10</sub> and PM<sub>2.5</sub>) using the WRF-CMAQ two-way coupled model during a high PM<sub>2.5</sub> event observed in South Korea from February 17 to March 15, 2019. The impact was quantified by analyzing differences in meteorological variables and PM concentrations between simulations that included DAF (i.e., YF) and those that did not include DAF (i.e., NF). Overall, the effect of DAF (YF minus NF) was more pronounced as the PM concentration in the air increased. The DAF effect was generally stronger in the northwestern and/or western regions of South Korea than in the eastern regions. In the study area, primarily over land, the DAF effect was found to decrease solar radiation, planetary boundary layer height, air temperature, and wind speed, with average changes of -0.54 MJ m<sup>-2</sup>, -29 m, -0.14°C, and -0.04 m s<sup>-1</sup>, respectively, while increasing relative humidity by an average of +0.8%. These changes in meteorological variables due to the DAF effect resulted in an average increase in PM<sub>10 </sub>and PM<sub>2.5</sub> concentrations (0.25 μg m<sup>-3</sup> and 0.49 μg m<sup>-3</sup>, respectively) over land in South Korea. Interestingly, in the southern regions, the DAF effect led to a decrease in PM concentrations, primarily due to a reduction in the concentrations of secondary aerosols (mainly NO₃<sup>-</sup>) and precursors (mainly HNO₃) and partly due to differences in meteorological conditions (small changes in wind speed and relative humidity). In addition, the magnitude of the DAF effect in ocean areas was found to be mostly lower than that in land areas.
