Abstract: A snow making nozzle assembly in which streams of water emerge from removable slotted nozzle plates and are injected into a high velocity air stream to atomize the water and project the atomized water into an atmosphere having an ambient temperature below 32 degrees Fahrenheit. The depth of slots in the removable nozzle plates vary to produce a more consistent snow pattern than prior art assemblies. The present invention has a higher operating efficiency due to the ability to easily clean the water nozzles and to adjust the water flow rate to match the existing atmospheric conditions.
