1.1雨滴谱数据在双线偏振雷达雨滴谱反演及降水估测中的应用利用双线偏振雷达在广东鹤山（2014年5月1日至6月15日）参加华南前汛期暴雨外场观测试验，获得大量的暴雨、大暴雨野外观测资料，对资料进行了质量控制。利用雨滴谱观测数据分析了华南前汛期滴谱结构，重新拟合偏振参量进行降水估测，提高了偏振雷达定量降水估测精度；利用双线偏振雷达在西藏那曲（7月1日至8月31日）开展的第3次青藏高原科学考察野外观测试验数据，研究了高原对流云的宏、微观特征。（胡志群）
1.1Application of rain drop size distribution(DSD)data to DSD retrieval and precipitation estimationwith a dual polarization radarHeavy rain data were observed with the dual linear polarization radar and disdrometer from May1to June15,2014in Heshan,Guangdong Province during pre-rainy season in South China.The dual polarization radardata were controlled in quality before usage.By using the data observed with the disdrometers,the drop sizedistribution(DSD)of the pre-rainy season in South China was analyzed,and the algorithm of radar quantitativeprecipitation estimation(QPE)by polarimetric parameters was refi tted to improve the accuracy of QPE.TheDSD was also retrieved by a dual linear polarization radar in Naqu Tibet during the third Tibetan PlateauAtmospheric Science Experiment(from July1to August31,2014),which was compared with distrometers.(HuZhiqun)
