Abstract

A field test conducted on 10 January 1987 confirmed a postulate that rapid ice nucleation occurs on wet silver iodide aerosols at temperatures below -6 C. The postulate was developed from laboratory tests and is consistent with results from winter orographic cloud seeding programs which have used ground generators sited at mountain tops and along ridges, where they are located within supercooled water clouds during their operation.
