The secret of the artificial snow world

Ice and snow to snowball， snowman， happy ice and snow carnival ... ... are the childrens winter expectations. But if not snow or snow is not big， then how to create a snow and ice world？

“Snow Canon”

People can use the "snow canon" snow machine to achieve artificial snow. There are two principles of snow machine： one is to use ice-making device to produce small piecies of ice， and then using ice as raw material to snow. The other is the use of traditional high-pressure water and air mixed with snow， that is， water into a dedicated nozzle or spray gun， where high-pressure air will divide water into tiny particles and then blast into the cold outside the air. Before falling to the ground， these small droplets quickly freeze and solidify into ice crystals， that is the snow flakes we know.

Does artificial snow affect the environment？

Usually 1 ton of water can make two cubic meters of snow， a snow machine water consumption per hour for 15 to 16 tons， the water can also be recycled. Within the ice carnival and ski resort artificial snow， the vast majority of air evaporation or through to the ground， can not be recycled， resulting in a waste. Ski resort snow drift will be a lot of loss of groundwater， increasing mountain drought in the mountains. Artificial snow will also have some damage to vegetation.

What is the difference between artificial snow and natural snow？

Artificial snow is achieved on the basis of a natural snowflake landing principle， but as it does not experience the long life process of snowflakes， it is different from natural ones. Hidden behind every natural snowflake a variety of weather information from its formation to falling down. It was said that the world can not find two exactly same snowflakes. But the artificial snow formation time is short， fast growth， hence snowflake shape is basically the same. Within natural snowfall in the next day there will be changes in hardness， and it will be very slippery， so the snow is very enjoyable. But the artificial snow is not only of high production costs， the quality is not good， which does not feel like the same.

The Whisper of Stars

In the Arctic， the temperature drops to minus 50 ℃， water vapor breathed out by people will directly change into small snowflakes. These little snowflakes collide with each other and emit sound like flipping pages， and the explorer calls this wonderful voice "whisper of stars". It can be seen， as long as the conditions to meet the crystallization of water vapor condensate， we can in a variety of occasions to create a beautiful artificial snow.
