| 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. |

| Keywords: | APPI PPI area precipitation average adjustment distribution pattern of precipitation |
