| 摘要: |
| 依据无线电-声探测技术的原理及方法，对16组RASS虚温数据与探空仪数据进行对比研究，分析其误差成因，并提出修正方法。研究结果表明：RASS和探空仪实测虚温数据的变化趋势一致性较好；RASS测量的虚温误差随着高度的增加，有先降低再增大然后再降低的特征；风场、湿度、地杂波等因素对RASS虚温探测有较大影响；利用测得的垂直速度修正RASS探测公式，进行修正计算，发现能够减小误差。该研究可为提高RASS系统的测量精度并开展进一步业务应用提供参考。 |

| Abstract: |
| The theory of radio-acoustic sounding technology (RASS) is analyzed. 16 groups of RASS data and radiosonde data are compared; the error reason and the correction method are researched. The research results show that the change trends of the two kinds of data show good uniformity. The error of RASS decreases at low height, increases in the middle, and decreases too at high height. The effects of wind, humidity and clutter are obvious. Using vertical motion to amend the formula of RASS and make correcting calculation. It is found that the method can decrease error. The research can provide reference for improving the precision of RASS and further business application. |
| Key words: radio-acoustic sounding system (RASS) virtual temperature radiosonde data error correction vertical motion |
