Winter Olympics Cold Facts: Snowfall can affect the track and visibility
Why are ski races afraid of snow? First of all, snow will have an impact on the track. First, the accompanying heating when it snows will affect the snow temperature and snow quality of the track, so the type and amount of waxing of the athlete's snowboard needs to be adjusted accordingly. Second, the new snow brought about by snowfall will make the surface of the track soft and the friction increase, which is not conducive to the players. Low visibility in snowy weather can affect the vision of athletes and referees. Especially for athletes who are sliding at high speeds, it is very dangerous.
