Abstract Based on the daily tropopause original meteorological data obtained from real-time high-altitude detection of the Hezuo sounding station in Gannan at 07:00 from 2013 to 2022,the annual and monthly average meteorological elements of the tropopause,including the average height,average temperature,average pressure,and frequency of occurrence of the tropopause are calculated month by month from 2013 to 2022 .The results show that the first tropopause is dominant from January to May and from October to December in Gannan region.The frequency of the first tropopause is low in summer and autumn,so the second tropopause is mainly in summer and autumn.The monthly mean height of tropopause is opposite to the monthly mean temperature and monthly mean pressure.The composite tropopause is mainly the first tropopause.From 2013 to 2022,the two types of tropopause annual sounding height,average temperature and average pressure are opposite and negative correlation,and the correlation of the first tropopause was greater than that of the second tropopause.
