Plain Language Summary: We examine how mountain upslope geometry controls aerosol effects on orographic precipitation from shallow warm convective clouds through idealized simulations using the WRF model with a bin microphysics scheme. The windward-width of the mountain controls advection timescale of liquid drops. Greater aerosol loading leads to reduction and downstream shift of precipitation. The aerosol effects are more clearly seen when the windward-width of the mountain is narrower.
