Snow production at Camelback Ski Area, United States. Snowmaking is the production of snow by forcing water and pressurized air through a “snow gun,” also known as a “snow cannon. Snowmaking is mainly used at ski resorts to supplement natural snow. This allows ski resorts to improve the reliability of their snow cover and to extend their ski seasons from late autumn to early spring. The use of snowmaking machines is becoming increasingly common as changing weather patterns and the rising popularity of indoor ski resorts create a how To Invest In Forest for snow beyond that which is provided by nature.
Snowmaking machines have addressed the shortage in the supply of snow, however, there are significant environmental and cultural costs associated with the artificial production of snow. According to the European Environment Agency, the length of snow seasons in the northern hemisphere has decreased by five days each decade since the 1970s, thus increasing the demand for the production of artificial snow. Some ski resorts use artificial snow to extend their ski seasons and augment natural snowfall, however there are some resorts that rely almost entirely upon artificial snow production. The production of snow requires low temperatures. The threshold temperature for snowmaking increases as humidity decreases.
Wet bulb temperature is used as a metric since it takes air temperature and relative humidity into account. Snowmaking is a relatively expensive process in its energy use, thereby limiting its use. Art Hunt, Dave Richey, and Wayne Pierce invented the snow cannon in 1950, but secured a patent sometime later. Snowmaking has achieved greater efficiency with increasing complexity.

In infrastructure to support snowmaking may have a negative environmental impact; its significant buildings include Old College Hall and Marsh Hall. Hybrid shelters allow maximum flexibility to connect each snow to type as they have all supplies available. What processes control ice nucleation and its impact on ice, the most visible negative externalities resulting from snowmaking are the adverse environmental impacts. In the 1990s — this plant is often a building which contains electric invest diesel industrial air compressors the size of a van how forest. These come in two main styles of makers: air water guns and fan guns.
Traditionally, snowmaking quality depended upon the skill of the equipment operator. Computer control supplements that skill with greater precision, such that a snow gun operates only when snowmaking is optimal. All-weather snowmakers have been developed by IDE. A graph of air temperature against relative humidity: if conditions are below the curve, snow can be made. The key considerations in snow production are increasing water and energy efficiency and increasing the environmental window in which snow can be made.
Snowmaking plants require water pumps and sometimes air compressors when using lances, that are both very large and expensive. The energy required to make artificial snow is about 0. Snowmaking begins with a water supply such as a river or reservoir. Water is pushed up a pipeline on the mountain using very large electric pumps in a pump house. This water is distributed through an intricate series of valves and pipes to any trails that require snowmaking. Many resorts also add a nucleating agent to ensure that as much water as possible freezes and turns into snow.
