The formation of advection fog is closely associated with the characteristics of the aerosol particles, including the chemical composition, mass of the nuclei, particle size, and concentration. Both microphysical and microphysical processes are considered. In the microphysical model, the evolution of wind components, water vapor content, liquid water content and potential temperature under the influences of vertical turbulent diffusion, turbulent momentum, and turbulent energy transfers are taken into account. In the microphysical model, the supersaturating effect is incorporated with the surface tension and hygroscopic material solution. The results show that the aerosol particles with the higher number density, larger size nuclei, the heavier mass of the nuclei, and the higher ratio of the Van’s Hoff factor to the molecular weight favor the formation of the lower visibility advection fogs with stronger vertical energy transfer during the nucleation and condensation time period.
