摘　　要：文章利用吉林省气象局1971—2023年超过32℃的高温日数及1980—2023年5—8月各月极端最高气温资料,选择线性倾向估计法和滑动平均法对吉林省高温天气变化特征进行分析。结果表明:吉林省平均年≥32℃的高温日数整体以增加趋势为主,但变化不显著;1980—2023年吉林省年极端最高气温平均值为37.4℃,整体以升高趋势为主,气候变化倾向率为0.0577℃/a,通过了显著性水平检验,说明吉林省年极端最高气温升高趋势较为显著。The article uses the data of high temperature days exceeding 32℃from 1971 to 2023 and extreme maximum temperatures from May to August of 1980 to 2023 from Jilin Provincial Meteorological Bureau to analyze the characteristics of high temperature weather changes in Jilin Province using linear trend estimation and moving average methods.The results indicate that the overall trend of high temperature days with an average annual temperature of≥32℃in Jilin Province is increasing,but the change is not significant.The average annual extreme maximum temperature in Jilin Province from 1980 to 2023 is 37.4℃,with an overall upward trend.The climate change tendency rate is 0.0577℃/a,which has passed the significance level test and indicates that the annual extreme maximum temperature in Jilin Province has a significant upward trend.
