ABSTRACT:
A method and apparatus for making snow by discharging a water spray at high velosity from a first nozzle positioned adjacent the top of a tower into a freezing ambient atmosphere and further discharging a jet stream of air under pressure into the throat of the water spray thereby forming a plume of atomized water. The efficiency and capabilities of snow making are enhanced by further discharging water under pressure into the atmosphere through at least one additional nozzle, positioned adjacent to the first nozzle, in the form of an additional spray which is directed into the plume. The additional nozzle may be above, below or beside the first nozzle and if two or more of the additional nozzles are provided, they may be positioned on the same side or on opposite sides of the first nozzle, and the supply of water delivered to the discharge nozzles need not be regulated for varying subfreezing temperatures. The snow tower is preferably rotatable about a vertical axis and is also preferably bent outwardly at an intermediate portion thereof to position the nozzles further away from the base of the tower to assist in regulated placement of the snow in varying wind conditions.
