摘　　要：基于齐齐哈尔国家基本气象站2020年1和7月高空气象平行观测数据以及GTS1型数字探空仪2009—2019年1和7月观测数据,运用Ryan-Joiner方法进行正态性检验,采用平均偏差、绝对偏差、均方根误差和相对误差作为对比分析的评估指标,探讨GTS11、GTS12、GTS13与GTS1型数字探空仪在925~500 h Pa规定等压面上,测得的温度、相对湿度和位势高度的差异,分析GTS1型探空仪历史观测数据11 a旬平均值在5个规定等压面上的变化特征。结果表明:GTS11、GTS12、GTS13型3种探空仪测得的温度均低于GTS1型探空仪;相对湿度均高于GTS1型探空仪;位势高度略低于GTS1型探空仪,比对样本具有较好的一致性;GTS1型探空仪对温度、位势高度和相对湿度的测量值,在5个规定等压面上1和7月的变化趋势基本一致。Based on the comparative observation data obtained during the upper-air parallel observation of Qiqihar national ordinary station in January and July 2020,and the observation data obtained by GTS1 digital radiosonde in January and July during 2009—2019,the Ryan-Joiner method was used for normality test,the average deviation,absolute deviation,root mean square error and relative error are used as evaluation indexes for comparative analysis,the difference of temperature,geopotential height and relative humidity among GTS11 digital radiosonde,GTS12 digital radiosonde,GTS13 digital radiosonde and GTS1 digital radiosonde is analyzed,and the variation characteristics of the 11 a ten-day average values of GTS1 radiosonde historical observation data on the five specified isobaric surfaces are analyzed. The results indicate that the temperature of GTS11 digital radiosonde,GTS12 digital radiosonde and GTS13 digital radiosonde is lower than that of GTS1 digital radiosonde,the relative humidity of GTS11 digital radiosonde,GTS12 digital radiosonde and GTS13 digital radiosonde is higher than that of GTS1 digital radiosonde,and the geopotential height of GTS11 digital radiosonde,GTS12 digital radiosonde and GTS13 digital radiosonde is slightly lower than that of GTS1 digital radiosonde,and there is a good consistency between the comparison samples. The temperature,geopotential height and relative humidity of GTS1 digital radiosonde show the same trend in January and July on the five specified isobaric surfaces.
