摘　　要：利用吉林省1961—2020年冬季逐日降水、风速和最高气温观测资料,对影响吉林省冬季旅游出行的气象要素及其变化特征进行了分析,并对冬季旅游出行气象条件进行评估。结果表明:吉林省冬季平均无降雪时间长,2级以下风力的日数较多,日最高气温在-12℃以上的日数占冬季总日数的近9成。吉林省冬季非常适宜和适宜旅游的平均日数为128.6 d,占冬季总日数的85.2%,增多趋势为4.1 d/10 a。在气候变暖背景下,气象要素突变后的1991—2020年非常适宜和适宜旅游的日数明显增多,平均可达135.1 d,占冬季总日数近九成,但此间气象要素滑动均方差增大也导致两者的不稳定性加大。Based on the observation data of daily precipitation,wind speed,and maximum temperature in winter from 1961 to 2020 in Jilin province,the meteorological factors and their variations affecting winter tourism travel in Jilin province were analyzed,and the meteorological conditions for winter tourism travel were further evaluated.The results show that the average winter snowless period in Jilin province is long,the days with wind speed below grade 2 appear frequently,and the days with a daily maximum temperature of greater than-12℃account for around 90%of the total winter days.There are 128.6 days highly suitable and suitable for tourism in winter in Jilin province,accounting for 85.2%of the total winter days with an increasing trend of 4.1 d/10 a.In the context of climate warming,the highly suitable and suitable days for tourism increased significantly from 1991 to 2020 after the sudden meteorology variations with the average days of 135.1 accounting for nearly 90%of the total winter days.However,the increase of the sliding mean square deviations of the highly suitable and suitable days also leads to an increase in their instability.
