We conducted model simulations on sea breeze event on 24 August 2000 in Houston using the Weather Research and Forecasting (WRF) model with a two-moment bulk microphysical scheme. Both aerosol direct and indirect effects on cloud and precipitation processes during the sea breeze were investigated. Our study shows that aerosols have significant impacts on sea breeze strength, cloud microphysical properties, and precipitation. Contrasting the simulations with ARE with the simulations without ARE suggests that the aerosol direct effects should be included into model simulations.
