This caused it to produce snow unexpectedly.

In order to cover the increasing demand for artificially produced snow, more and more reservoirs and storage ponds are being built near the pistes.<\/p>\n<p>In order to optimise the energy efficiency of technical snow production, various methods have been invented in recent years to &#8220;treat&#8221; the water prior to artificial snowmaking. The US company Snomax, for example, has developed a process in which bacterial proteins are added to the water to help the water droplets freeze faster. These crystallization nuclei enable water to freeze even at higher temperatures.<\/p>\n<p>As the method is highly controversial, it may not be used in all ski areas or may only be used to a limited extent in many places. The German Ski Federation, for example, emphasises that chemical agents are only used on ski racing tracks in order to create constant competition conditions. Generally, however, no chemicals are necessary for the production of artificial snow.<\/p>\n<h2 id=\"machines-for-snowmaking\">Machines for Snowmaking<\/h2>\n<p>The technical processes for snowmaking mimic the natural formation of snow. Small drops of water freeze and turn into snow crystals. In the ski area, both snow cannons and snow lances are used to produce artificial snow.<\/p>\n<h3>Artificial Snow from a Snow Cannon<\/h3>\n<p>In most cases, the so-called propeller cannon is used for artificial snowmaking. The core element of this machine is a large propeller, which is supplied with water and electricity and generates a strong flow of air. The water is sprayed through nozzles in front of the propeller and transported from the compressed air stream to the cold, dry winter air. Depending on the weather conditions, the size of the water droplets can be adjusted to produce the best possible artificial snow. At a low humidity (approx. 30%), this procedure can already be used at +1\u00b0C, at 80% humidity, below -4\u00b0C is required. The higher the air humidity, the lower the outside temperatures must be.<\/p>\n<h3>Artificial Snow from a Snow Lance<\/h3>\n<p>Snow lances are another method of generating snow. These devices, which look like thin lantern poles, are permanently installed at the edge of the piste. They blow out atomized water together with compressed air, creating fine snow dust that trickles onto the slope.<\/p>\n<h3>Artificial Snow from Artificial Clouds<\/h3>\n<p>A completely new technology is the generation of new snow from artificial clouds, which was developed by a team of scientists associated with engineer Michael Bacher. The test of an artificial cloud installed in an open-air laboratory in the <a href=\"https:\/\/www.snowtrex.co.uk\/austria\/obergurgl_hochgurgl\/ski-area.html\" target=\"_blank\" rel=\"noopener noreferrer\">Obergurgl-Hochgurgl ski area<\/a> has been running since November 2014. The entire facility is three and a half meters high and the balloon has a diameter of two and a half meters. A construct consisting of two &#8220;clouds&#8221; sits on a tripod. The heart of the construction is a cloud chamber, which makes it possible to mix water droplets and ice grains. Water droplets are sprayed into the cloud chamber to create a small artificial cloud. Due to the low ambient temperature (below freezing), the droplets cool down without freezing themselves. Crystallization nuclei are introduced into this fog &#8211; small frozen ice plates, so to speak. These grains grow into larger crystals and finally fall out of the cloud container as snow. The process imitates the process in a real cloud, resulting in real snow crystals. The technology is as simple as it is ingenious.<\/p>\n<h2 id=\"environmental-influences-of-artificial-snow\">Environmental Influences of Artificial Snow<\/h2>\n<p>Time and time again, the question of whether artificial snow harms nature or not is disputed. The high energy and water consumption for artificial snow production, which has a long-term impact on the environment, is undisputed.<\/p>\n<p>Artificial snow also has a different form than natural snow, which can have a negative impact on the mountain ecosystem. The flakes, which naturally fall from the sky, have a hexagonal crystalline shape. The frozen, artificially produced water droplets, on the other hand, have a round shape. As a result, these &#8220;flakes&#8221; have a higher density and melt more slowly. The slower defrosting of artificial snow delays plant growth. This can damage the plants lying under the snow cover if they still have to struggle with the condensation from the artificial snow in spring. The regeneration phase of the soil and plants is therefore sometimes severely disturbed, so that even in summer, brown trails on the mountain reveal where an artificial snow slope has been.<\/p>\n<div class=\"tt-post-image-wrapper tt-post-image-wrapper-full\">\n            <div class=\"tt-image-copyright-container\">\n                <a href=\"https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" data-wrapped=\"true\" class=\"wp-image-55622 size-Artikelbild_gro\u00df\" title=\"In spring, plants on the mountain struggle especially where there was still an artificial snow piste in winter.\" src=\"https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-729x486.jpg\" alt=\"In spring, plants on the mountain struggle especially where there was still an artificial snow piste in winter.\" width=\"729\" height=\"486\" srcset=\"https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-729x487.jpg 729w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-300x200.jpg 300w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-1024x683.jpg 1024w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-768x513.jpg 768w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-468x312.jpg 468w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-999x666.jpg 999w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-645x430.jpg 645w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-552x368.jpg 552w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-405x270.jpg 405w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-336x224.jpg 336w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-276x184.jpg 276w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-234x156.jpg 234w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-192x128.jpg 192w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr-120x80.jpg 120w, https:\/\/www.snowtrex.co.uk\/magazine\/files\/2022\/11\/RS15408_shutterstock_1032769378-bearbeitet-scr.jpg 1440w\" sizes=\"(min-width: 1009px) 729px, (min-width: 819px) 594px, (min-width: 569px) 729px, (min-width: 449px) 468px, 348px\" \/><\/a><div class=\"tt-image-copyright\" data-image-id=\"55622\">\u00a9 Bachkova Natalia\/shutterstock.de<\/div>\n            <\/div>\n            <div class=\"tt-post-caption\">In spring, plants on the mountain struggle especially where there was still an artificial snow piste in winter.<\/div>\n         <\/div > \n<h2 id=\"advantages-of-artificial-snow\">Advantages of Artificial Snow<\/h2>\n<p>Despite the criticism, technically produced snow also has some advantages: On the one hand, its composition is almost always the same and therefore more &#8220;predictable&#8221; for skiers. Natural snow, on the other hand, can range from very powdery to very sticky, depending on its water content.<\/p>\n<p>In addition, artificial snow thaws much more slowly than natural snow and thus offers winter sports fans a longer skiing experience. This is because artificial snow has a higher water content than natural snow: while one cubic metre of natural snow can weigh up to 400 kg, the same amount of artificial snow weighs up to 800 kg. The compressed shape of the snow grains slows down the dew process. So if you can still see white snow stripes on the slopes in summer, then it is most probably artificial snow.<\/p>\n<p>Last but not least, artificial snow offers all winter sports fans a certain guarantee of snow. If the season doesn&#8217;t have a good turnout of natural snow, then thanks to snow cannons, it doesn&#8217;t mean that the entire skiing holiday will be ruined.<\/p>\n<p>Want to learn more <a href=\"https:\/\/www.snowtrex.co.uk\/magazine\/safe-skiing\/snow-lesson\/\" target=\"_blank\" rel=\"noopener noreferrer\">facts about snow<\/a>?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Winter sports fans expect perfectly groomed pistes with thick blankets of snow during their ski holiday.
