Abstract

Laboratory work showed that organic compounds have considerable promise as cloud-seeding agents. The following substances gave complete nucleation: phloroglucinol at −2C, trichlorobenzene at −12C, D(+)-Raffinose at −14C, trimesic acid at −15C, and melamine at −15C. Thirty-two organic compounds were investigated. The tests were conducted in a deepfreeze cloud chamber and a Bigg-Warner chamber. Field tests by the University of Chicago (Braham, 1963) confirmed the activity of phloroglucinol.

Theoretical analysis indicates that activity of organic icing nuclei is determined by configuration of electric link-dipole moments in the molecule.
