Snowmaking
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. Indoor ski slopes use snowmaking. They can generally do so year-round as they have climate-controlled environments. The use of snowmaking machines has become more common as changing weather patterns and the popularity of indoor ski resorts create a demand 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 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 dema ...

Snow Cannon Pagla Boden
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ski Resort
A ski resort is a resort developed for skiing, snowboarding, and other winter sports. In Europe, most ski resorts are towns or villages in or adjacent to a ski area – a mountainous area with pistes (ski trails) and a ski lift system. In North America, it is more common for ski areas to exist well away from towns, so ski resorts usually are destination resorts, often purpose-built and self-contained, where skiing is the main activity. Ski resort Ski resorts are located on both Northern and Southern Hemispheres on all continents except Antarctica. They typically are located on mountains, as they require a large slope. They also need to receive sufficient snow (at least in combination with artificial snowmaking, unless the resort uses dry ski slopes). High concentrations of ski resorts are located in the Alps, Scandinavia, western and eastern North America, and Japan. There are also ski resorts in the Andes, scattered across central Asia, and in Australia and New Zea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indoor Ski Slope
Indoor skiing is done in a climate-controlled environment with artificially produced snow. This enables skiing and snowboarding to take place regardless of outdoor temperatures. Facilities for both alpine skiing and nordic skiing are available. History Since the early 20th century, there have been four major stages in the evolution of indoor snow centres. Firstly, centres that had no refrigeration and used an artificial mixture of materials to create a surface substance something like snow, the first of these opened in Austria and Germany in the 1920s. The first recorded indoor “snow” slope was created at Berlin’s Automobilhalle in April 1927 gaining worldwide attention. According to contemporary reports a wooden slope was created about 720 feet long and sixty feet wide. The "snow" substitute used was invented and later patented by a British diplomat, L. C. Ayscough, and involved a mixture of powdered mica, soda crystals and sawdust spread on a brush matting surfac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2022 Winter Olympics
The 2022 Winter Olympics (2022年冬季奥林匹克运动会), officially called the XXIV Olympic Winter Games () and commonly known as Beijing 2022 (2022), was an international winter multi-sport event held from 4 to 20 February 2022 in Beijing, China, and surrounding areas with competition in selected events beginning 2 February 2022. It was the 24th edition of the Winter Olympic Games. Beijing was selected as host city in 2015 at the 128th IOC Session in Kuala Lumpur, Malaysia, marking its second time hosting the Olympics, and the last of three consecutive Olympics hosted in East Asia following the 2018 Winter Olympics in Pyeongchang County, South Korea, and the 2020 Summer Olympics in Tokyo, Japan. Having previously hosted the 2008 Summer Olympics, Beijing became the first city to have hosted both the Summer and Winter Olympics. The venues for the Games were concentrated upon Beijing, its suburb Yanqing District, and Zhangjiakou, with some events (including the cere ...

Spiegel Online
''Der Spiegel (online)'' is a German news website. Before the renaming in January 2020, the website's name was ''Spiegel Online'' (short ''SPON''). It was founded in 1994 as the online offshoot of the German news magazine, ''Der Spiegel'', with a staff of journalists working independently of the magazine. Today, it is the most frequently quoted online media product in Germany. ''Spiegel Online International'', a section featuring articles translated into English, was launched in autumn 2004. In 2019, its editorial office was merged with the one of the printed Spiegel and in 2020, the website was renamed accordingly. Company and editorial staff The news website ''Der Spiegel (online)'' is run by Der Spiegel GmbH & Co. KG (formerly Spiegel Online GmbH & Co. KG), itself a wholly owned subsidiary of Spiegel-Verlag. The editorial offices of the news website and the print magazine ''Der Spiegel'' were separate operations, that had their own offices, authors and content until January ...

Smiggin Holes, New South Wales
Smiggin Holes is a village in the ski resort area of Snowy Mountains of New South Wales, Australia, in the Snowy Monaro Regional Council. It is primarily a winter-only resort village. It is within the Kosciuszko National Park, and is administered by New South Wales Department of Environment and Climate Change. Access to the village is via road. There is an access fee payable to the national park, and motor vehicles are not permitted to stay overnight in the winter months. Smiggin Holes is one of four villages making up the Perisher Ski Resort. It is situated above sea level. The name Smiggin Holes is of Scottish origin. The trampling of hundreds of cattle consuming rock salt that graziers had placed there, caused depressions that filled with water. These depressions were called "the smiggin holes". The year 1939 signified the start of Smiggin Holes as a destination for skiers. Smiggin Holes is widely regarded as one of the best beginners' ski resorts on the Australian snowfiel ...

Canmore, Alberta
Canmore is a town in Alberta, Canada, located approximately west of Calgary near the southeast boundary of Banff National Park. It is located in the Bow Valley within Alberta's Rocky Mountains. The town shares a border with Kananaskis Country to the west and south and the Municipal District of Bighorn No. 8 to the north and east. With a population of 14,798 in 2020, Canmore is the ninth-largest town in Alberta. History Canmore was officially named in 1884 by Canadian Pacific Railway director Donald A. Smith (later 1st Baron Strathcona and Mount Royal). It was named after Malcolm III of Scotland who was also nicknamed Canmore. Canmore is Gaelic for "Big Chief". In 1886, Queen Victoria granted a coal mining charter to the town, and the No. 1 mine was opened in 1887. By the 1890s, a North-West Mounted Police barrack had been instated on Main Street, but it was vacated in 1927. The building was restored in 1989 and it is under the care of the Canmore Museum and Geoscien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nucleation
In thermodynamics, nucleation is the first step in the formation of either a new thermodynamic phase or structure via self-assembly or self-organization within a substance or mixture. Nucleation is typically defined to be the process that determines how long an observer has to wait before the new phase or self-organized structure appears. For example, if a volume of water is cooled (at atmospheric pressure) below 0°C, it will tend to freeze into ice, but volumes of water cooled only a few degrees below 0°C often stay completely free of ice for long periods (supercooling). At these conditions, nucleation of ice is either slow or does not occur at all. However, at lower temperatures nucleation is fast, and ice crystals appear after little or no delay. Nucleation is a common mechanism which generates first-order phase transitions, and it is the start of the process of forming a new thermodynamic phase. In contrast, new phases at continuous phase transitions start to form im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
