How do you host a Winter Olympics in a snow-challenged city? AP explains.
A person works at a snow making machine on a hill overlooking cross-country skiing practice before the 2022 Winter Olympics, Wednesday, Feb. 2, 2022, in Zhangjiakou, China.
Snowmaking equipment tries to duplicate this process, artificially, by spraying atomized water into the air along with mechanically created nucleators -- tiny ice crystals — that act as seeds for the manufactured snowflakes. This process has been around for decades: simulated snow was first used at the 1980 Olympics in Lake Placid, New York.TechnoAlpin won the bid to supply the Beijing games with snowmaking equipment, a contract worth $22 million.
Snow lances, meanwhile, are up to 10 meters tall and don’t have fans, instead using gravity to carry the snowmaking mixture to the ground, making it a bit more like natural snowfall.Beijing and Zhanghiakou are both not far from the Gobi Desert and are “highly water stressed,” China Water Risk, a Hong Kong-based consultancy, said in a 2019 report.
“The regions where the snow sport events will be held are constantly very cold,” the IOC said in a statement. “This allows a very efficient snow production and does not require the constant reproduction of snow,” like ski resorts elsewhere with fluctuating temperatures that cause snowmelt.
