Abstract: An apparatus for generating falling snow and having an upright inner cylinder, a cloud vapor machine and a snow seed feeder connected to the cylinder near the lower end thereof, an air velocity adjustment pipe connected between the upper and lower ends thereof and a blower in the pipe for adjusting the flow velocity of air inside the pipe to adjust the flow of air in the inner cylinder, and a cooling tower surrounding the inner cylinder and a cooler for cooling the air in the cooling tower for cooling the inner cylinder.

Abstract: An artificial snow making apparatus including a mechanism for changing artificial snow generated therein to wet snow which includes an apparatus for making artificial snow and a test chamber located therebelow for receiving the generated snow. An air channel is located within the test chamber and connected to the artificial snow generating mechanism. A blower sends air through the air channel for mixing with and carrying the generated snow along a flow path. A mechanism for supplying heated and humidified air to the air channel is disposed at a portion of the flow path which is downstream from where the generated snow is supplied to the air channel. A sample fitting frame is disposed in the air channel at a position downstream of the position along the air channel at which the heated and humidified air is supplied thereto.

Abstract: A televising apparatus is provided in a chamber of a snowfall testing system in which various testing conditions may be varied which effect the characteristics of particles of snow generated in the chamber. The televising apparatus has a television camera with an object lens for televising the particles of snow falling in the chamber, and a film feeder for feeding a transparent film, onto which the particles fall, past the object lens. A television camera transfer unit moves the television camera and object lens relative to the transparent film such that the particles falling thereon may be properly and fully televised. Furthermore, a focus regulator is used to move the film feeder and film relative to (toward and away) from the object lens so that the particles falling on the film may be focused. By televising the particles, results of the testing conditions are obtained which can be used to determine the effects of the testing conditions in generating snow within the chamber.
