Here's the problem
Why the race related to "snow"
Instead, will you be "afraid" of snow?
Let's get to it
Let's take a look at it
1
How does snowfall affect events?
Snow can affect the snow temperature and quality of the track.
The accompanying heating up when it snows affects the snow temperature and quality of the track. Therefore, the type and amount of athlete snowboard waxing need to be adjusted accordingly.
Snow affects the player's performance.
The new snow cover brought about by snowfall will make the surface of the track soft and the friction increase, which is not conducive to the players.
Snow can also affect the safety of the game.
Low visibility in snowy weather can affect the line of sight of athletes and referees, and is also very dangerous for athletes who are sliding at high speeds.
For example, ski jumping is recognized as one of the most weather-susceptible competitions, with extremely high requirements for instantaneous wind speed, requiring "instantaneous wind speed of less than 4 m/s and no crosswind", otherwise the direction and line of sight of athletes in the air will be affected, and it is very dangerous to lose control.
Therefore, after the snow drifts on the field, the staff will immediately clean up the snow on the track, which can ensure the normal progress of the event and reduce the probability of athlete injury.

When will the game be suspended?
The track management said that whether to stop the race is not related to the amount of snow, but the viscosity of the snow surface of the track will be suspended until it reaches a certain standard.
Zhao Weidong, a spokesman for the Beijing Winter Olympics Organizing Committee, said that the staff at the venue will submit the relevant meteorological data to the experts of the International Federation of Individual Sports, who will decide whether to change the schedule. In general, snowfall does not affect the schedule. However, under extreme weather conditions, the Beijing Winter Olympic Organizing Committee will work closely with stakeholders such as the International Olympic Committee, international sports federations, including Olympic broadcast service companies, to start the relevant procedures for changing the competition schedule in a timely manner to minimize adverse effects.

How will the Beijing Winter Olympics cope with snowfall?
In addition to preparing in advance, the on-site support work of the Beijing Winter Olympics is also in place.
The head of the Genting venue group in Zhangjiakou said that during the Winter Olympics, there are often strong winds and cooling weather, and a windshield wall has been built under the guidance of experts of the International Snow Federation to reduce the probability of athletes being injured and reduce the probability of delaying or canceling competitions. In addition, in the case of heavy snow, it is also necessary to achieve "go with the flow". Prevent excessive snow melting agents and keep the arena clean and tidy.
At the National Ski Jumping Center, snowflakes also fell on the 12th. Before the snow stopped, the track leveling operation of the operation support team began, and the staff pressed and stepped on the track to provide a safe track environment for the athletes to land.
At the National Cross-Country Ski Center, athletes used the opened snow trough for the 12th race. If there is snow in the snow trough, it will greatly affect the speed and performance of the athletes. This is due to the fact that the mountain operation team of the venue started 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.

Future weather
The Central Meteorological Observatory continued to issue a blue warning of blizzard this morning (13th), and it is expected that there will be heavy snow in parts of central Inner Mongolia, northern Shanxi, north-central Hebei, northern Beijing, southern Tianjin, eastern and southern Liaoning, and Xinjiang along the Tianshan Mountains; the new snow depth in some areas is 1 to 4 centimeters, and the local area can reach more than 6 centimeters.
Tomorrow, the snow in North China will basically stop, the main snowfall area will be transferred to the northeast, and there will be light to moderate snow in parts of northeast Inner Mongolia, northwest and east of Heilongjiang, eastern Jilin and eastern Liaoning, among which there is heavy snow in parts of eastern Jilin and other places.
