摘　　要：文章利用邢台高空探测站仪器换型平行观测期间获得的对比观测资料,对数字探空仪GTS13、GTS12与现用数字探空仪GTS1的位势高度平均差值与温度平均差通过绘制图表的形式进行分析。结果表明:GTS13在100hPa以下高度无明显系统差异,GTS12在400hPa以下高度系统差异不明显;两套新型探空仪系统差异20:00明显小于08:00,说明系统之间的差异与观测时间有直接关系;由于厂家不同,探空仪的原材料和制作工艺的不同也造成了观测数据的差异性。Using the comparative observation data obtained during the conversion of the upper-air sounding station instruments to parallel observation in Xingtai,the average difference of geopotential height and temperature among GTS13 digital sounder,GTS12 digital sounder and GTS1 current digital sounder is analyzed by means of chart.The results show that the GTS13 digital sounder has no obvious systematic difference in altitude below 100hPa,while GTS12 digital sounder has no obvious systematic difference in altitude below 400hPa.But the system difference between the two new types of sounder at 20:00 is less than that at 08:00.It is shown that the difference between the systems is directly related to the observation time.Due to the different manufacturers,the different raw materials and production techniques of sounder also result in the difference of observation data.
