| 摘要: |
| 根据2020年1－4、7月，3种新型探空仪在林芝探空站使用情况，选取最多有效资料,采用静态和动态分析的方法对其性能评估，结果表明：①1－4月新仪器不合格、重放仪器的百分率，由大到小排列，不合格：GTS13、GTS11、GTS12，重放：GTS11、GTS12、GTS13。② 7月20：00规定等压面层700～250hpa区间上，新仪器观测要素值的平均与标准值比较，偏差绝对值的最大偏差，由大到小排列，温度：GTS13、GTS11、GTS12。位势高度：GTS13、GTS11、GTS12。③新仪器单日20：00探空秒数据要素值与标准值比较，偏差的绝对值范围内出现次数所上百分比，由大到到小顺序排列，温度≤0.50℃：GTS13、GTS11、GTS12；湿度≤5%：GTS13、GTS11、GTS12。 |

| Abstract: |
| According to the operation of three new types of radiosondes at the sounding station in Nyingchi from January to April and July in 2020, the most available data are selected, and their performance is evaluated by static and dynamic analysis:(1) from January to April, the percentage of unqualified and replayed instruments arranged from big to small, unqualified: GTS13, GTS11, GTS12, replayed: GTS11, GTS12, GTS13. (2) on the interval between 700 and 250hpa of the ISOBARIC surface layer as defined at 20:00 July, the maximum deviation of the absolute value of the deviation is arranged from large to small, and the temperature is GTS13, GTS11, GTS12. Geopotential height: GTS13, GTS11, GTS12. (3) compared with the standard values of 20:00 radiosonde second data elements of the new instrument in a single day, the absolute values of the deviation range from large to small in order, temperature ≤0.50 °C: Gts13, Gts11, GTS12; humidity ≤5% : GTS13, GTS11, GTS12. |
