利用舍肥、马鞍山2部多普勒雷达联合观测资料及多部多普勒雷达合成和连续调整技术(MUSCAT),在笛卡尔坐标下反演得到三维风场.将得到的风场通过由CAPS(center for analysisand prediction of storm)研发的ARPS(advanced regional prediction system v5.2.4)模式及数据处理系统ADAS(ARPS data analysis system)进行同化试验.结果表明,反演风场信息可以改善短时模拟场、特别是风场的状况;但由于对湿度场等的改进较小,致使预报的3 h降水量与实况有出入.

Three dimensional wind field are obtained in Cartesian coordinate with Hefei and Maanshan dual-Doppler radars united observations by means of a Multiple-Doppler Synthesis and Continuity Ad-justment Technique(MUSCAT). The retrieval wind field is assimilated in mesoscale numerical model ARPS (advanced regional prediction system), developed by Center for Analysis and Prediction of Storm (CAPS), and ARPS Data Analysis System(ADAS). The results show that the retrieval wind field can improve effectively short-time simulation field, especially wind field. For the condition of humidity without reflectivity information, however, there are some differences between the predicted and observed 3 h precipitation as a result of the humidity field improved less.
