Why are snow projects afraid of snow?
◆ First, the heating up when snow will affect the snow temperature and snow quality of the track, so the type and amount of athlete snowboard waxing need to be adjusted accordingly;
◆ Second, the new snow will make the track surface soft and the friction increase, which is not conducive to the athletes;
◆ Third, the low visibility in snowy weather will affect the vision of athletes and referees, especially for athletes who are sliding at high speeds.
Natural snow fluffy and wet Artificial snow is more suitable for competition
In fact, the impact of natural snowfall on the competition, especially on snow sports, is still quite large. It was fresh snow, very fluffy, and it was relatively humid.
Looking at the layer below, this is our artificial snow, very hard, and our snow groomer has been pressed many times, which is what meets the conditions for our athletes to compete. So the staff is clearing the snow, which can ensure that our event is running normally and reduce the probability of athlete injuries.
To what extent does the snow stop the game? The reporter learned from the track management that this has nothing to do with the amount of snow, but the viscosity of the snow surface of the track needs to reach a certain standard before the race is suspended. There will be professionals who will be responsible for checking and judging.
The NTO of the Winter Olympics at the Yanqing Alpine Stadium braved the fierce wind to clear the snow
Since the opening of the Beijing Winter Olympics, the athletes on the ice and snow field have undoubtedly attracted the attention of the whole world, and behind the dazzling, it is inseparable from the silent work of more than 1800 Winter Olympic NTOs. What does the NTO do at the Winter Olympics? It is a general term for the technical representatives, competition officials, referees and measurement officials of the competition. For the NTO, the more wind and snow, the harder it is, and it is necessary to clear the snow on the track to avoid injuries to athletes. If the snow keeps falling, it must be cleared all the time, otherwise it will be more difficult to clear when it accumulates.
On February 13, domestic technical officials ("NTOs") at the Yanqing Alpine Stadium braved the wind to clear the snow. According to the reporter's understanding, the work of repairing the ski tracks should not be underestimated, and it is necessary to make the surface of the slopes smooth and smooth to ensure that no matter how many players appear, the ski tracks are in a relatively perfect state to ensure the fairness of the game. This requires the NTO to keep an eye on weather changes and track conditions, clearing snow and repairing the slopes in the shortest possible time with the highest standards.

Ski doctors are fully staffed and can be transported first-hand in the first time
On the 12th, Genting Ski Park welcomed the snowboard obstacle course chase mixed team final in the snow and wind. The Genting venue complex also conducted official training. All 138 medical staff were on duty, and on the slope obstacle course of more than 400 meters, the medical team of 4 points and 2 spare teams were waiting.
The National Ski Jumping Center levels the track to prevent snow and wind
At the National Ski Jumping Center, known as "Snow Ruyi", snowflakes also fell on the 12th. Before the snow stopped, the track leveling operation of the operation support team began, and they pressed and stepped on the track to provide a safe track environment for the athletes to land. Some people worry that if the snowfall is accompanied by strong winds, how will the "snow ruyi" be overwhelmed? Originally, the natural drop of this valley of Chongli ancient poplar trees was more than 130 meters, and there were mountains on both sides that could shield or weaken the wind, and the later construction of the windproof net ensured that the wind speed in the jumping area of the site was below 4 meters per second.
The National Cross-Country Skiing Center wind-blown snow clears the snow trough
On the 12th, the National Cross-Country Skiing Center also held a women's 4X5 km relay competition, athletes used the open snow trough in the competition, if there is snow in the snow trough, it will greatly affect the speed and performance of athletes.
The mountain operation team of the venue activated the emergency mechanism in advance, arranged a snow clearing team of 20 people, and carried out snow blowing operations on the 5-kilometer track to fully ensure the operation of the event.
In the history of the Winter Olympics, there have also been postponements due to heavy snowfall. For example, at the 1998 Winter Olympics in Nagano, the alpine skiing event had to change the date of the competition several times because of the heavy snowfall, which would cause some interference to the athletes' competition status, but the impact of snowfall on all athletes was relatively fair. I hope that China's Gu Ailing and Yang Shuorui can adjust their state and achieve the desired results after the qualification resumes!
