In the past 2 days, snow has begun to fall in some parts of the country, because the Winter Olympics are carried out on ice and snow, so many friends feel that snow is very good, which will make the game look better, but the actual situation is not so, some games have been postponed, so why will snow have such a big impact on the Olympic games? Today we're going to talk about how the weather affects the race.
The first thing we want to say is that the ice games are not affected by any weather conditions because they are all played in indoor venues.
Snow sports are different, like mainland athletes Gu Ailing and Yang Shuorui participating in the freestyle ski women's steeplechase qualification, which was postponed because of snowy weather.
At the same time, there are also competitions such as cross-country skiing, biathlon and ski jumping, so the question is, why are snow competitions afraid of snow?
This is because these Olympic events have extremely high requirements for the venue, and we see that the snow in the track is not ordinary snow, natural snow, in fact, they are artificial snow, which I talked about in the previous video, also called ice snow.
The surface of the ice-like snow has a thin layer of hard ice shell, which can reduce the friction between the skis and the snowboard, improve the performance of the competition, and effectively protect the athlete's body.
For the Beijing Winter Olympics, the mainland's scientific researchers have worked hard to realize artificial snow technology that meets the Olympic standards, and have also realized the localization of ice and snow hardness measuring instruments, ice and snow particle size measuring instruments, and professional monitoring equipment for ice-like snow tracks, comprehensively breaking the monopoly of foreign technology and realizing low-cost freedom of snow use.
When there is snow weather, the first inevitable impact on the existing track, because the snow will make the track become soft, the friction becomes larger, the speed slows down, and then affects the athlete's play, resulting in a large area of performance decline, and the game will be greatly discounted. For example, freestyle skiing, if there is no certain speed to ensure, there is no way to make pleasing moves, and it will directly affect the personal safety of athletes.
And the piste we see is not just a layer of artificial snow by the snowmaker, it also needs to be repeatedly crushed to meet the hardness requirements of the race. Even cross-country skiing requires a layer of artificial snow to be laid on it.
Therefore, the impact of natural snow covering on the slopes is enormous.
In addition, snowy weather is usually accompanied by an increase in temperature, which can cause the temperature of the track to change, resulting in unstable snow quality.
The last point is that the snow weather will have strong winds and reduced visibility, if there is a strong wind, it will affect the athlete's movements, the difficulty of predicting increases, the difficulty of action increases, this time directly affects the safety of athletes. Low visibility will affect the line of sight of athletes, referees, and cameras, which also increases the risk factor for athletes who are sliding at high speeds.
To sum up, the ski competitions of the Winter Olympics are all carried out on artificial snow and cannot be affected by high winds and visibility. Seeing this, I believe everyone should understand it.
Therefore, when there is snow weather, the snow project is likely to be postponed.
Then the Beijing Winter Olympics are in full swing, and everyone should not forget to cheer for our Chinese athletes.
