Short summary
This study uses 1 km resolution Weather Research and Forecasting model coupled with
Chemistry (WRF-Chem) simulations to investigate how Lake Chaohu affects fine
particulate matter (PM2.5) in Hefei. The lake shows a diurnal reversal, increasing
daytime pollution by secondary aerosol formation and storage zones with suppressed
mixing and low deposition, while purifying urban air at night through enhanced vertical
mixing. Lake emission treatment affects lake-urban air quality assessments.
