Abstract With the changing climate, study of fog formation is essential due to impact complexity natural and anthropogenic aerosols. The evolution droplet size distribution in presence different aerosol species remains poorly understood. To make progress towards reducing uncertainty forecasts, Eulerian–Lagrangian particle‐based small‐scale model for diffusional growth droplets used better understand activation growth. simulations are performed using observed data from Winter Fog Experiment over Indira Gandhi International Airport, New Delhi. microphysical properties, such as number concentrations (Nd) liquid water content (LWC), important simulation, evaluated gain more insights. have shown properties at evolutionary stages.

This compared an existing parametrization parcel–direct numerical simulation calculation. hygroscopicity , which highly related aerosols condensation nuclei, taken into account demonstrate contribution chemistry formation. results highlight that prediction regulated by species.
