Abstract From January 10 to 13,2023,the temperature at Yanji Airport at 12:00-15:00 was abnormally high to more than 0 ℃.The highest temperature reached 3.8 ℃ at13:18 on the 11th.It causes the snow in the airport and on both sides of the runway to melt and freeze into thin ice again,which brings certain hidden dangers to the airport operation.This paper analyzes the hourly temperature data of Yanji Airport from January 2012 to January 2022 and the weather situation around January 11,2023 by using the big data of hourly temperature.The results show that the average temperature and maximum temperature in January 2023 show a wave-like trend.From January 10 to 13,2023,the weather situation is conducive to sinking and warming,which is one of the reasons for the abnormal high temperature.From January 10 to 13,2023,the weather circulation situation weakened the East Asian winter monsoon activity and the wind speed changed abnormally,resulting in abnormal high temperature.
