中文摘要: 应用上海中心气象台714数字化天气雷达的体积扫描资料所得到的不同高度上的CAPPI资料和低仰角时PPI资料,估算区域降水量并得到降水量分布形势。然后采用平均校准法进行了校准,最后又与用雨量计网测得的区域降水量及其分布形势作了比较,得到一些有意义的结果。
Abstract:Using the CAPPI data at different heights and the PPI data at loW elevation angle based on the 3 dimentional volume scaning data of 714 digital radar in the Shanghai Central Meteorological Observatory, the area precipitation is estimated and the distribution pattern is achieved. Then they are adjusted and compared with the measurement of the rain gauge network.
