Parsivel雨滴谱仪与多普勒天气雷达观测结果对比分析

利用收集到的降水雨滴谱资料与多普勒雷达的观测资料,将Parsivel激光降水粒子谱仪计算的回波强度与雷达观测的回波强度作以比较,结果表明：两者具有较好的一致性,雷达观测到的回波强度有低估的现象,并且降水强度越强,回波强度越大,雷达低估的现象越为明显。经过回波修正后,用统计的Z-I关系式估算的降水量与Parsivel测得的降水量更为接近,可以提高雷达定量估算降水的准确性。

Comparative analysis of observational results between Parsivel disdrometer and Doppler weather radar

Using the precipitation data observed by the Parsivel disdrometer and Doppler weather radar,and compared with echo intensities obtained by Parsivel laser particle spectrometer and radar observation,the results show that both have a good consistency,but the echo intensity observed by radar is underestimated.The heavier the precipitation is,the stronger the echo intensity is with obvious underestimation.After echo amended,the precipitation estimated by Z-I relationship is more closely to Parsivel measured,whi...
