朝阳新一代天气雷达分型Z-I关系降水估测模型

Precipitation Estimation Model of the New Generation Weather Radar Based on Z-I

利用2014年4-10月朝阳新一代天气雷达和自动站数据资料,对降水过程进行分型,采用最优化方法分析得到本地化Z-I关系,结果表明院降水估算准确率在65%~70%以上,大大提高了本地天气雷达定量估测降水的准确率,更大地发挥了新一代天气雷达的效益。

Using Chaoyang new generation weather radar and automatic station data from April to October in 2014, the precipitation process were classified and the optimization method of analysis to be localized Z-I relationship. The results showed that precipitation estimation accuracy in more than 65%-70% ,it could greatly improve the local weather radar quantitative precipitation estimation accuracy and greatly play the benefit of the new generation weather radar.
