A machine for producing artificial snow includes an elongated cylindrical outer casing with a frusto-conical discharge end; a similar inner casing, a tubeaxial fan in the outer casing for creating an annular stream of turbulent air at the discharge end of the outer casing; an adjustable turbine nozzle centrally located at or near the discharge end of the outer casing for spraying a stream of water droplets into the turbulent air to create a stream of water droplets and air; and nucleators at or near the discharge end of the outer casing for spraying very fine droplets of water or nuclei into the stream of water droplets and air, whereby, temperature permitting, a stream of artificial snow is created without large droplets of water or ice dribbling from the stream near the discharge end of the outer casing.
