在气候变化的大背景下,极端天气事件的发生概率增加,就连2022北京冬奥也遭遇了一次暖冬,那如果比赛当日如果没有足够降雪哪该怎么办呢?实际上,对于冰雪赛事而言,天然降雪一般很难满足冰雪赛事的竞赛条件,大部分滑雪场都需要用到造雪机。北京冬奥中气象保障团队除了运用造雪机之外,还运用了新技术去对雪进行维护以防止它融化,让运动员们可以放心滑雪。(Because of climate change, the probability of extreme weather events has increased and even the 2022 Beijing Winter Olympics has been hit by a warm winter. So, what happens if there is not enough snow on race day? In fact, for ski terrain, natural snowfall is generally difficult to meet the competition conditions for snow and ice events, and most ski resorts use snow-making machines. In addition to the use of snow machines, the Beijing Winter Olympics weather team also uses new technology to maintain the snow to prevent it from melting so that athletes can ski with pleasure.)
