SOME PROBLEMS CONCERNING THE TECHNIQUE OF SEEDING SUPERCOOLED STRATUS CLOUDS FOR THE PURPOSE OF SCATTERING THEM,
Abstract
A report on cloud seeding and dispersion of stratus clouds is presented. To update methods of inducing rain and dispersing clouds and fog, it is necessary to determine optimum intervals between the seeding lines. An experimental study was carried out by the Ukrainian Hydrometeorological Research Institute for this purpose in the following manner: after sounding the cloud layer and establishing its parameters, initial seeding was made to find the maximum width of crystallization zone. Then the seeding was repeated along five or six lines normal to the wind direction at the cloud top level. Experiments showed that for complete dispersal of clouds the stage of cloud development is an important factor in determining the interval between the seeding lines. The experiments also indicated that larger dosages of seeding substances produce complete dispersion of clouds in the growing phase. (Author)
