| 摘 要： | 利用高分辨率雷达定量估测降水的格点数据，与自动站实际观测到的降水量进行分析对比，发现雷达估测降水映射得到的自动站估测小时降水量与自动站实际观测的小时降水量的比值服从正态分布，以此来反推区域自动站实际观测的小时降水量的可信程度，并通过建立回归方程来对那些降水失真自动站作估计。以“菲特”台风期间的区域站降水量为例作了分析计算，结果表明雷达定量估测降水对自动站实际观测降水有良好的质控效果，值得进一步分析研究。

| Abstract: | The observed precipitation and high resolution grid data of precipitation estimated quantitatively with radar are analyzed and compared, and it is found that the ratios of the precipitation estimation with radar and observed precipitation obey normal distribution. Credibility of observed precipitation can be derived from above regularities, and moreover, the distortion of observed rainfall can be estimated by building a regression equation. The precipitation during Typhoon Fitow is analyzed and calculated, and results show that good effect is achieved in the quality control of the observed precipitation actually by using radar precipitation estimation. This topic is worth further study. |
