In this study

artificial snow is produced under natural conditions using a snowmaking machine

and the microscopic morphology of the snow crystals is obtained. The sizes of snow particles and the factors that influence them under various working conditions are subsequently analyzed

and the formation of artificial snow is deduced. The results show that the falling position

environmental temperature and humidity

and nozzle atomization particle size are important factors affecting snow particle diameter. Lower environmental temperature and humidity

as well as a smaller nozzle diameter

facilitate the formation of larger snow particles. When the snowmaker operates stably

the distribution of snow particle diameter is more non-uniform in distant areas than at the edges and middle regions. The measured snow particle size is approximately 0.3 mm

which is significantly larger than the atomization particle size of the nozzle (0.12 mm). This result indicates that snow particles collide during flight. Overall

this study is important for understanding the mechanisms of snow formation and the regulation of snow quality.
