The influence of sea salt aerosols on atmospheric environment in a typical sea-land-breeze circulation over Pearl River Estuary (PRE) during 9~13 September 2013 was investigated with the simulation based on the WRF-CMAQ modeling. The results indicated that the sea-breeze circulation was initiated at around 14:00 LST (local standard time) and subsequently reached its peak at around 17:00 LST, and formed a fan wind circulation along PRE. The mass concentration of Na+ in the Pearl River Delta (PRD) increased from 17:00 LST and reached the maximum value at around 02:00 LST the next day, then gradually decreased after 10:00 LST. The substantial chloride depletion was observed for the sea salt aerosols with more depletion being seen during daytime than nighttime, and more depletion for fine particles than coarse particles. Sensitivity experiments were respectively conducted with and without the emissions of sea salt aerosols in the model system. The results showed that the mass concentrations of HCl, SO42-, and NO3- all increased with the emissions and more increases were seen for HCl and NO3- than for SO42-. The peak concentration of HCl arrived earlier than that of Cl-. The SO42- concentration was mainly affected by the sulfate component in the emitted sea salt aerosols, while the NO3- concentration was mainly affected by both the chloride depletion and its dry deposition.
