Abstract: A snow making system comprises a cooling subsystem having a fan that draws a first air into the cooling subsystem and a turbine that expands a second air to produce an expanded air, with the cooling subsystem combining the first air and the expanded air to produce a high mass-flow, high-velocity, cooled air. A nozzle subsystem has a channel that receives the cooled air and a water injector that injects water into the cooled turbine air such that the water is atomized and frozen by the high-velocity cooled air. The system thereby produces frozen water nuclei in the absence of a nucleating nozzle. The remainder of the channel receives high-velocity, high mass-flow fan air and water injectors that inject water into said air such that water particles are partly atomized. The two flows then mix upon exiting the system and produce snow if ambient conditions permit.
