PCT No. PCT/FR86/00104 Sec. 371 Date Jan. 14, 1987 Sec. 102(e) Date Jan. 14, 1987 PCT Filed Mar. 26, 1986 PCT Pub. No. WO86/05864 PCT Pub. Date Oct. 9, 1986.An apparatus and process for generating artificial snow. The apparatus includes a plurality of spray nozzles mounted on each of a plurality of spraying ramps. The spray nozzles are mounted at the outlet of a diffuser directly within the flow of air therefrom. At least one of the ramps include a plurality of spraying nozzles for introducing seeding particles. The seeding particles can be produced through hydropneumatic nozzles. Alternatively, the seeding particles can be produced by using a cryogenic liquid or by using an apparatus for dispersing snow particles accumulated in the vicinity of the snow producing apparatus. To obtain the greatest possible quantity of freezable water, the temperature, relative humidity, and wind speed and direction are sensed by a programmable controller which thereby controls the fan, water source, and pressure regulator to thereby optimize the quantity of snow produced. In addition, the apparatus and process include steps for sensing a property of the snow crystals as they are formed by the snow generator of the present invention. The property sensed can be the variation of the dielectric constant of the snow particles over a predetermined range of frequencies.
