Study of the Possibility of Stimulating Cloud Convection by Solar Radiation Energy Absorbed in an Artificial Aerosol Layer

We consider the possibility of creating artificial clouds similar to Pyro formed in nature over large forest and other fires. It is assumed that creation an surface aerosol layer absorbs solar radiation can lead heating local air volumes initiate thermal convection. The such convection was examined theoretically using computational fluid dynamics software package suite FlowVision, which equations motion, energy mass transfer are solved relative variables. Numerical experiments showed principal initiating cloud only under some favorable atmospheric conditions (low wind speeds, temperature lapse rate greater than 8–9 °C/km), with area at least 5–10 km2 a duration its existence (heating) 30 min. To assess practical implementation this method, eight variants highly efficient smoke compositions were developed tested, two batches checkers weighing 25 kg, optimal size absorb radiation, produced. Calculations required dose based on results laboratory field tests for one experiment several thousand need be burned. consumption pyrotechnic composition (tens tons) about 1.5 times less burning petroleum products previously tested meteotrons. However, environmental safety purposes, full-scale application method advisable conduct away from populated areas.
