中文摘要: 利用1998年7月20～22日鄂东地区持续性特大暴雨的数字化天气雷达反演资料和雨量计网测量资料,采用变分技术校准雷达定量估测降水,结果表明:经变分法校准后的雷达估测降水不仅保留了雷达探测到的降水形势,并且与雨量计网测定的降水量之间的误差有明显的改进。
中文关键词: 变分法，数字化天气雷达，降水量
Abstract:With hourly special persisting rainstorm data from digital weather radar evaluations and gauge observations in the east of Hubei on the 20-22nd,July i n 1998, the characteristics of radar-detecting precipitation calibrated by vari ational method is studied Results prove that the radar estimations calibrated d oes not only keep the distribution condition of the rainfall before calibration, but also the errors from the comparison with gauge observations are improved re markably.
