摘　　要：文章利用甘南合作探空站2013-2022年高空实时探测取得的07:00资料中逐日对流层顶原始气象资料,将对流层顶年、月平均气象要素,包括对流层顶的平均高度、平均温度、平均气压和出现频率,逐月统计出2013-2022年的月平均值。结果表明:甘南地区15月、10-12月以第一对流层顶为主;夏、秋两季出现第一对流层顶的频率较低,故夏、秋季以第二对流层顶为主;两类对流层顶月平均高度与月平均温度、月平均气压趋势相反;复合对流层顶主要以第一对流层顶为主;20132022年两类对流层顶年探空高度、平均温度、平均气压走势相反,呈负相关,第一对流层顶相关性大于第二对流层顶。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.
