Abstract

A study of the dispersion of silver iodide emitted from the Ground-based Generators Network located on the eastern region of Cuba has been achieved. It has been used 29 study cases during the period 2005-2008 to determine the network effectiveness for the Cuban Cloud Seeding Program in that region. The numerical forecast model Mesoscale Model 5 Version 3 and the Calmet-Calpuff Modeling System were used to simulate the dispersion of silver iodide emitted from the network. Their concentrations over 0.1 ng/m3 at 2 000 and 6 500 m height above sea level have been analyzed in order to determine the possibility of dynamic seeding in convective supercooled clouds. The results showed that the network is not effective since the emitted aerosol does not reach the 6 500 m of height in the required concentrations so that the dynamical cloud seeding takes place. Sensitivity studies performed showed that increasing by over 12 times the current emission rate, reports of silver iodide concentrations at 6500 m to produce dynamical cloud seeding are obtained in very small areas. This work suggests deepening the study by mean of other numerical models provided the Calmet-Calpuff Modeling System limitations.
