Abstract

Measurements of cloud liquid water content and temperature were made along with visual observations in 32 traverses carried out in six warm cumulus clouds subjected to salt seeding. The results showed (i) a rise, of 1–2°C, in temperature, (ii) an increase, sometimes exceeding 200%, in liquid water content, and (iii) vertical growth, up to 60%, in seeded clouds which developed rain. The features noticed could be due to the possible dynamic effect of salt seeding in warm clouds.
