METHOD AND APPARATUS FOR PRODUCING SNOW USING ULTRASONIC WAVES

摘要

A method for producing snow comprises producing a group of waterdrops by jetting water or water together with compressed air from a nozzle into the atmosphere of 0 .degree.C or less, and freezing the group of waterdrops jetted by applying ultrasonic waves to the group of waterdrops. An apparatus for producing snow comprises a jetting apparatus for producing a group of waterdrops by jetting water or water together with compressed air into the atmosphere of 0 .degree.C or less, and an ultrasonic wave generator for applying ultrasonic waves to the group of waterdrops jetted by the jetting apparatus.
