亚冬会期间尚志市滑雪气象指数变化特征分析

Analysis of the Variation Characteristics of Skiing Meteorological Index in Shangzhi During the Asian Winter Games

利用尚志市1981-2024年逐日气象资料,分析亚冬会赛前、赛中和赛后各旬以及赛期(2月7-14日)的滑雪气象指数变化特征,为哈尔滨亚冬会滑雪赛场充分利用气象数据,做好赛事期间的气象条件预测等保障提供参考依据。结果表明:亚冬会赛中2月上旬-2月中旬滑雪气象指数达1级或2级标准的概率均超过88%,相比赛前和赛后较大。赛期滑雪气象指数为1级和2级标准的日数占比分别为50.9%和39.5%;平均每年赛期降雪总量为1.7 mm,降雪事件主要是无降雪或小雪,出现中雪及以上的概率极低;日平均风速为2.6 m/s,影响滑雪等级的风力主要为3级及以下风力,而出现4~5级风力的概率极低,出现5级以上风力的概率为0;日最高气温为-7.4℃,影响滑雪等级的最高气温主要介于-16℃~10℃,而出现最高气温<-16℃的概率极低。

Using daily meteorological data of Shangzhi City from 1981 to 2024,this study analyzes the changes of skiing meteorological indices before,during,and after the Asian Winter Games,as well as during the competition period(February 7-14).The aim is to provide a reference for the Harbin Asian Winter Games skiing venue to fully utilize meteorological data and predict meteorological conditions during the event.The results show that the probability of skiing meteorological index reaching Class 1 or Class 2 from early February to mid-February in the Asian Winter Games is more than 88%,which is larger than that before and after the games.During the competition period,the number of days with the skiing meteorological index of Class 1 and 2 standards accounted for 50.9%and 39.5%respectively.The average annual snowfall during the competition is 1.7 mm,and the snowfall events are mainly no snow or light snow,and the probability of moderate snow and above is very low.The average daily wind speed is 2.6 m/s,the wind that affects the skiing grade is mainly level 3 and below the grade,and the probability of 4 to 5 grade wind is very low,the probability of more than 5 grade wind is 0.The daily maximum temperature is-7.4℃,the maximum temperature affecting the skiing grade is mainly from-16℃to 10℃,and the probability of the maximum temperature less than-16℃is very low.
