Generally this class of technologies can be effectively used in presence of a suitable relief and structure of air flows.
For effective realization of influence reagent should be delivered directly under the basis of a cloud or at least in area of an ascending flow,
that forms a cloud. The saturation of surface air with nucleuses of condensation (crystallization) undoubtedly is meaningful for stimulation of precipitation.
However taking into consideration duration of lifting of nucleuses up to a level of a cloud and decrease of their concentration during lift, the influence is
meaningful only on the large territories and with use of multiple generators
(for example in the anti-hail projects of France and Spain on the areas more than 55 000 kms 2 involved about 700 ground generators).
For rather local influences the most effect reaches when generators are disposed on prevailing eminences or at least when some ejection of aerosol above the surface is arranged.
The company develops a number of modeling installations for realization of influence from the surface of the ground. However parameters of installations (jet systems, generators of vortical rings, pyrotechnic generators of various types) should be adhered to a direct situation of realization of influence. Below some photos of various modeling generators developed by our company are submitted.
