| 摘 要： | 利用酒泉高空站L波段雷达-GTS1电子探空仪系统与“59-701”系统1个月的同步观测资料,对该站使用L波段探空系统后高空探测资料变化情况进行分析评估。通过直接对比、与国家气象中心数值预报6 h初估场比较和相关性检验分析,得到各规定等压面上位势高度、温度、湿度、风向、风速等的偏差和均一性检验结果。结果表明,酒泉站使用L波段雷达系统后,温度、高度、风向、风速记录平均而言未产生跳变,对流层上层湿度记录离散性小,新老系统的相对湿度差随高度增加而增加,记录准确率有明显的改善。在温度较低的对流层上层,59型探空仪测定的相对湿度偏高,GTS1型电子探空仪测定的湿度数据更接近国际上比较先进的探空仪。 |

| Abstract: | A comparative analysis is made of the radiosonde-L-band radar system and the 59-701 system by means of the one-month synchronously observing data from the Jiuquan station,and the change of the data after the introduction of the L-band radar system is evaluated.The results indicate that generally speaking, the temperature,height,wind direction and velocity did not change obviously after using the L-band radar system;the relative humidity difference between the two systems increases with increasing altitude;the accuracy of the humidity records in the upper troposphere is improved obviously. |
