Side-skim Seeding for Convective Cloud Modificatiooin


  • Norihiko Fukuta


Ice crystals growing by vapor diffusion at -10 C, primarily as short solid columns, fall faster than those developing dendritically at lower temperatures o~ those of long columnar shapes at warmer temperatures. To keep artificially induced crystals around -I0 C as long as possible and thus cause them to grow and fall faster in order to enter the rapid riming growth regime, cumulus clouds should be seeded at the -10 C level just inside the cloud, rather than at the center, using liquid propane or other nucleant with little temperature dependence.
