how is snow made?

Answer 1

Snow begins in the atmosphere as water condenses into a tiny droplet. As more and more water vapor condenses onto its surface, the droplet grows. Cold air then freezes this water into an ice crystal.

Each ice crystal has a unique shape that depends on the surrounding air's temperature and water vapor content. If it is below freezing and there is a lot of water vapor in the air, the crystal grows six evenly spaced branches. More and more water vapor collects on these branches and freezes, making the ice crystal increasingly heavy. Eventually, the ice crystal falls from the sky, leaving the cloud of precipitation that it helped to form. As it falls, the crystal continues to grow by picking up more water vapor.

As it descends, the ice crystal can come into contact with warmer air that makes it melt somewhat. This melting acts like a glue, causing crystals to bond together into larger flakes, forming what many people think of as the "classic" fluffy snowflake. If the crystals melt too much and then refreeze as they get closer to Earth's surface, the precipitation falls as sleet instead of snow.

Once on the ground, snow will remain if temperatures are cold enough to keep it from melting. Glaciers that form on mountains, for example, are made up of snow that accumulates on the ground and eventually turns to ice.

If you are talking about Man-made snow:

snow cannon (also called snowgun, snow maker or snow fan) is a device used to produce snow artificially. The term artificial snow is mistakenly used for the produced snow; a more accurate term is man-made snow. A snow cannon works by atomizing water with compressed air and allowing it to freeze into snow. The device is often used by ski hills and ski resorts to supplement naturally occurring snow and extend the skiing season. However, for the purposes of skiing, most enthusiasts consider man-made snow to be inferior to naturally occurring snow. This is due to the fact that man-made snow does not form snow flakes like natural snow; instead, man made snow forms crystals that are more dense than natural snowflakes.

A snow cannon usually consists of a high pressure water nozzle onto which a high pressure jet of air is blown. Pressurized water flows from a high pressure hose, which forms small droplets of water. The droplets are then blown on by a high pressure air hose to break them up even farther into tiny droplets (almost a mist). If the surrounding air temperature is near or below freezing, the droplets of water tend to evaporate and rapidly cool. This method only works when the ambient air is at 0°C (32°F) or lower.

If the relative humidity is low (10%), artificial snow can be made when the temperature is as high as 4.5°C (40 °F). This is possible because of the rapid evaporation and evaporative cooling caused by the low humidity. If the wet bulb temperature is below -2°C (28.4°F), snow can be made. There is a direct relationship between relative humidity and air temperature which affects the quality of snow.

The snow cannon was invented by Art Hunt, Dave Richey and Wayne Pierce in 1950.

When you say "made," I'm not sure if you mean like at ski areas , or how does snow form. And, this is not entirely scientific…I may have some technical terms wrong. Let's start with natural...

Moisture is always in the air. When enough of it gathers, and the temperature is cold enough, the molecules of water crystallize and fall of their own weight; this can happen because the moisture in the atmosphere is not in the form of crystals. There is little resistance to If the upper air is not cold enough for snow, the molecules gather together into droplets and fall as rain. If it freezes on the way down, then we have sleet. If it falls as rain and the ground temperatures are cold, then we have an ice storm.

Machine made snow. Easy… Either water and air are mixed in certain ratios in your basic snow guns, or water is sprayed in a fine mist into a powerful fan. Voila!!! Snow. It’s not artificial; it’s snow.

Answer 3

Water vapor in the air is cooled below the freezing point ( 0 C) As the water first turns to a liquid. If there are some impurities in the air such as dust and/or chemicals, it will freeze around the particles (known as the nucleus), making a snow flake.

There are man-made devices that can be seen at ski hills. They blow water and a nucleating agent into the air (which needs to be below freezing) and when it settles to the ground, it is snow, though not as a good quality of snow as the natural stuff.

Answer 4

Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes. Since it is composed of small ice particles it is a granular material. It has an open and therefore soft structure, unless packed by external pressure.

Snow forms in the atmosphere, not at the surface. So snow can fall when surface temperatures are above freezing as long as atmospheric temperatures are below freezing and the air contains a minimum moisture level (the exact level varies according to temperature).
According to the Weather Glossary, provided by the Weather Channel Interactive, Inc, lake effect snow is "snow showers that are created when cold dry air passes over a large warmer lake, such as one of the Great Lakes, and picks up moisture and heat."

Answer 5

snow is made of ice crystals. Tiny crystals of frozen water stick together to make a flake.Snow occurs differently than most people think--it is not from frozen raindrops! Moisture in the air freezes into crystals.The same thing happens in the atmosphere. Water vapor in air at temperatures below freezing can turn directly into ice crystals. The ice crystals form on miniature particles. That is the beginning of what we call snow

Answer 6

Snow is made by water vapour in a storm system when warm moist air collides with cold air. The water vapour condenses into water particles which freeze into ice crystals which join together in the storm system and while falling to the ground. In the north most rain begins as snow.

Answer 7

I imagine you mean how is it made by man and not nature. Its a combination of pressure, lowish temperature and water. The theory is using Boyle's law - Pressure times volume divided by temperature = a constant. It is then shot out of a nozzle onto ski slopes and is very effective. For example, this year all of the snow in Soldeau Andorra was man-made in early January and it was enough to keep a lot of lifts open until the natural snow came in late January

Answer 8

Clouds that are quickly cooled to where what would have fallen as rain freezes high enough in the atmosphere that they form loose crystals that fall as snow. Think of it as the rain drops froze right before they became rain drops so that is why snow is so light and fluffy. Sleet however are rain drops that have formed but freeze in the lower atmosphere. Hail is the same principal but sleet is like a sprinkle and hail is like a thunderstorm.

Answer 9

pretend snow is incredibly made up of the same stuff actual snow is placed the version is that it incredibly is device generated. Water is used and as quickly as the temperature is low sufficient they are able to pump it with the aid of snow canons coming up synthetic snow. it incredibly is form of greater complicated yet thats incredibly what occurs.

Answer 10

In a snow factory at the North Pole. It's right next to Santa's workshop.
