The time evolution of phase composition and other main characteristics of tropical cumulus clouds measured as part of the Cuban Weather Modification Program in the Camag�ey Meteorological Site are presented. Measurements were made from an AN-26 instrumented aircraft at a flight level nearly 6 km, with air temperature ranging from -7 to -10 0C. Clouds top heights ranged from 6 to 8 km. Ice concentration obtained for particles greater than 120 microns, was less than 2-3 per liter for young developing cumuli. The ratio of solid to total water for this clouds was less than 0.1- 0.2. Moderate increases of ice content were detected 12 - 15 minutes after first echo in an x - band radar. The analysis of the time evolution of the phase composition allowed finding a seeding window for the development of ice particle of 20 minutes after first echo.
