摘　　要：为了解探空仪换型引起的观测数据的差异,文章运用方差分析、多重比较等手段对2020年三亚探空仪平行观测期间GTS1-2(旧型)与GTS13(新型)两种探空仪在925~500 hPa等压面上的温度、相对湿度和层间厚度三个观测要素进行定量对比。结果表明:两种探空仪在不同规定等压面上的温度差具有方差齐性,显示两种探空仪有较好的测温稳定性;两种探空仪在不同规定等压面上的相对湿度差具有很好的方差齐性,显示两种探空仪有良好的测湿稳定性;两种探空仪在不同规定等压面上的层间厚度差不具有方差齐性,显示两种探空仪有较差的层间厚度测量稳定性,但两种仪器在层间厚度的测量结果上具有良好的一致性。研究结果可为三亚探空仪换型前后数据的均一化和进一步提高探空观测质量提供支撑。In order to understand the differences in observation data caused by the replacement of radiosondes,this article uses methods such as variance analysis and multiple comparisons to quantitatively compare the temperature,relative humidity,and interlayer thickness of two radiosondes,GTS1-2(old type)and GTS13(new type),on the 925 hPa to 500 hPa isobaric surface during the parallel observation period of Sanya radiosondes in 2020.The results show that the temperature difference between the two radiosondes on different prescribed isobaric surfaces has homogeneity of variance,indicating that the two radiosondes have good temperature stability.The relative humidity difference between the two radiosondes on different prescribed isobaric surfaces has good homogeneity of variance,indicating that the two radiosondes have good humidity measurement stability.The interlayer thickness difference between the two radiosondes on different prescribed isobaric surfaces does not have homogeneity of variance,indicating poor stability in interlayer thickness measurement.However,the two instruments have good consistency in interlayer thickness measurement results.The research results can provide support for the homogenization of data before and after the replacement of the Sanya radiosondes,and further improve the quality of sounding observations.
