Abstract: A mixture of compressed air and pressurized water is ejected from snow-making nozzle means in a cold ambient atmosphere and the mixture is expanded and cooled to form a stream of falling snow particles. Into this stream, high velocity jets of chilled water droplets are discharged at points ahead of the nozzle means along generally converging paths of travel. Water droplet portions adhering to the snow particles undergo progressive freezing to produce a cumulative crystallization and growth in the size of the snow particles. The water droplets are jetted at a velocity greatly exceeding the velocity of the snow particles in the stream, and these particles are accelerated and caused to travel over greatly extended distances for a given flow of compressed air supplied, for example, at a rate customarily utilized of one hundred cubic feet per minute.
