The effects on orographic clouds and precipitation of aerosol loading have been investigated by simulating an idealized mixed‐phase orographic cloud using the Weather Research Forecast ( WRF ) mesoscale model coupled with a detailed bin microphysics scheme. The results show that the total precipitation amount is reduced by 23.4% with increasing aerosol loading on the orographic clouds. Moreover, increasing aerosol loading will increase the number concentration of cloud droplets in small size range (<19.84 µm in diameter) and lead to a decrease in the peak diameter from 12.5 to 9.92 µm .
