The effectiveness of warm fog clearing by seeding with hygroscopic nuclei was studied numerically. A parcel of air with a known distribution of fog droplets was assumed to be seeded with hygroscopic nuclei. While new drops were formed upon the seeding nuclei due to condensation, the fog droplets became smaller due to evaporation. The new distribution of drops and the corresponding visibility are given for 60 and 100 sec after seeding. The results indicate that seeding may be effective if the type of fog to be cleared is known as to droplet distribution and the seeding nuclei are chosen accordingly.
