Short summary
This study investigates how fast-moving air currents close to the ground influence the vertical transport of dust over Hefei in eastern China. Using laser-based wind observations during two dust events, it shows that one event rapidly brings dust down to the surface, whereas the other keeps dust suspended at higher altitudes and delays surface pollution. These findings improve understanding of how dust is redistributed in the lower atmosphere and help improve weather and air-quality forecasts.
