Application of Variational Method to Calibrating Precipitation Evaluated with Digital Weather Radar

Wang Yehong 1 Cui Chunguang 1 Zhao Yuchun 2 Min Airong 1 (1 Wuhan Heavy Rain Institute, 430074) (2 Wuhan Central Weat her Office)  
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
