Diffusion of ground-generated Silver Iodide to cumulus cloud formation levels

Jack McPartland, Arlin Super

Abstract


During the past three decades, most experimental convective cloud seeding programs have relied exclusively on aircraft for delivery of ice nuclei to the clouds.  However, some commercial operators have made extensive use of ground-based generators intending to accomplish the same objective....  During the past three decades, most experimental convective cloud seeding programs have relied exclusively on aircraft for delivery of ice nuclei to the clouds. However, some commercial operators have made extensive use of ground-based generators intending to accomplish the same objective.....  The exploratory Agl tracing program discussed here in has shown that vertical diffusion, during summer afternoons in central Montana, was often sufficient to transport Agl into small cumulus clouds based 1.5 to 2.5 km above ground within a few to several kilometers of the ground-based generators.....
