人工造雪引是利用雪花降落的原理将水和空气混合在适宜的条件下制造出雪花而用于各种未能下雪又需要雪的地方。人们通过造雪机来实现人工造雪的，造雪机的原理是：将水注入一个专用喷嘴或喷枪，在那里接触到高压空气，高压空气将水流分割成微小的粒子并喷入寒冷的外部空气中，在落到地面以前这些小水滴凝固成冰晶，也就是人们看到的雪花。人工造雪。气温必须达到零度或零度以下，才可以造雪。

自从韦恩·皮尔斯利用一个油漆喷雾压缩机，喷嘴和一些用来给花木浇水的软管造出一台造雪机以 来，造雪机的基本原理并没有任何变化。将水注入一个专用喷嘴或喷枪，在那里接触到高压空气，高压空气将水流分割成微小的粒子并喷入寒冷的外部空气中，在落到地面以前这些小水滴凝固成冰晶，也就是人们看到的雪花。

原理听起来很简单，但是实行起来却要困难和昂贵得多。在北京及东北地区独特的气候条件，结果是气候条件在几千米的范围内会有显著的变化。

Funa uses the principle of snowflake falling to mix water and air under suitable conditions to produce snowflakes, which can be used in various places where snow is not available but needed. Funa is realized by snowmaking machine. The principle of snowmaking machine is to inject water into a special nozzle or spray gun, where it comes into contact with high-pressure air. The high-pressure air divides the water flow into tiny particles and sprays them into the cold outside air. Before falling to the ground, these small water droplets solidify into ice crystals, that is, snowflakes that people see. Funa. The temperature must reach zero or below zero before snow can be made. Since Wayne Pierce used a paint spray compressor, nozzles and some hoses for watering flowers and trees to build a snowmobile, the basic principle of the snowmobile has not changed. Water is injected into a special nozzle or spray gun, where it comes into contact with high-pressure air, which divides the water flow into tiny particles and sprays them into the cold outside air. Before falling to the ground, these small water droplets solidify into ice crystals, that is, snowflakes seen by people. The principle sounds simple, but it is much more difficult and expensive to implement. Because of the unique climatic conditions in Beijing and Northeast China, the climatic conditions will change significantly within several kilometers.
