Snow will have an impact on the track. First, the temperature and quality of the snow on the track will be affected with the warming of the snow, so the type and amount of waxing of athletes' skis need to be adjusted accordingly. Second, the new snow brought by snowfall will soften the track surface and increase friction, which is not conducive to the players' play. However, low visibility in snowy days will affect the sight of athletes and referees. Especially for high-speed skaters, it is very dangerous. So, to what extent will snowfall stop the game? The reporter learned from the track management that this has nothing to do with the amount of snow, but it is necessary to stop the race after the consistency of the snow surface on the track reaches a certain standard. There will be professionals responsible for checking and judging.
