摘　　要：文章通过GPZ2型自动探空系统在锡林浩特国家气候观象台开展为期94 d的动态性能测试试验工作为基础,在试验期间,对自动探空系统在台站选址、安装测试、业务稳定性测试及大风天气下自动探空系统的自动释放能力进行测试和评估。并且对瞬时值(0.0 s)及同一时间自动气象站气温、气压、相对湿度和探空仪放飞后(0.1 s)的气温、气压、相对湿度值进行对比分析。试验结果表明:其在北方寒冷风大地区能正常运行,自动放球成功率达到98.9%,探空仪状态识别率100%,满足技术指标要求。试验过程中0.0 s和0.1 s气温、气压、相对湿度差值相较与正常变率较大,探空仪上升速率与气压随高度实际变率不符,放球前后气温、湿度差值较大,不符合温、湿度变化规律。并且对仪器设备出现的问题进行总结,对气温、气压、相对湿度0.0 s和0.1 s差值较大问题提出合理建议,为今后自动探空系统业务化运行提供科学依据。Based on the 94 day dynamic performance test of GPZ2 automatic sounding system at Xilinhot National Climate Observatory,this paper tests and evaluates the automatic release ability of automatic sounding system in station location,installation test,business stability test and its performance in windy weather.We compared the value of air temperature,pressure and humidity observed by the automatic station(0.0 s)and GPZ2 automatic radiosonde system(0.1 s).The test results show that:it can operate normally in the northern cold and windy area,the success rate of automatic ball release is 98.9%,and the recognition rate of radiosonde state is 100%,which meets the requirements of technical indicators.During the test,the difference of air temperature,air pressure and humidity between 0.0 s and 0.1 s is larger than the normal rate of variation,the rising rate of radiosonde is inconsistent with the actual variation of air pressure with height,and the difference of air temperature and humidity before and after the ball release is larger,which does not conform to the law of temperature and humidity.In addition,the paper summarizes the problems of the instrument and equipment,and puts forward reasonable suggestions for the large difference between 0.0 s and 0.1 s of temperature,air pressure and humidity,so as to provide scientific basis for the operational operation of the automatic sounding system in the future.
