Abstract

Radar quantitative measurement of precipitation has more advantage in time and space, but the relationship between the change of terrain and precipitation type has great rate. Studying on the radar quantitative measurement of precipitation is one of the main development ways to improve the radar applied ability utilize radar volume scan data. The reflectivity difference of Tianshui, Qingyang and Lanzhou weather radars on the equidistant line were contrasted when they simultaneously observe and the radar echo and precipitation retrieved if occur short-duration heavy rainfall were also analysed by using radar volume scan data. The result shows that: There is no obvious difference when echo more than 10 dBz; Comparing the region station with automatic station of precipitation, comparing the weather scale is less caused by short-duration heavy precipitation than other rainfall type, on the other hand, this conclusion also proved by statistic of radar echo. There are the scale about which 75% of the heavy precipitation are less than 20 km; The original station can't perfectly characterize the local precipitation is demonstrated; The estimated quantitative precipitation through packet of estimation, holistic and categorical Z-I relations were studied. The result shows that: Categorical Z-I relation is better than others on describe precipitation type in the Northeast edge of Tibetan Plateau, thus better solving the problem of underestimated light rain and overestimated heavy rain，and when rainfall belongs to 15~20 mm·h-1 is best.
