摘要
2014年9月28日山东地面人工增雨试验区使用WR-98火箭成功进行一次增雨作业。采用新一代多普勒雷达、探空和自动站10min雨量资料,利用选取对比云和雷达跟踪目标云的方法,探讨了这次人工增雨作业后的雷达响应和地面雨量的关系。结果表明:火箭催化13min后目标云顶开始升高,19min后目标云回波增强了3dBz,25min后目标云VIL从2.5kg/m^2增加到3kg/m^2。目标云所经过的3个雨量站10min雨量具有同样的增大趋势,从时间和地理位置分析这些变化与火箭人工增雨有关。
A ground precipitation enhancement was conducted on 28 September 2014in Shandong.By means of CINRA radar and radiosonde data and 10-min automatic precipitation,using the methods of contrast clouds and radar tracking target clouds,the relation between radar responses and rainfall after the precipitation enhancement operation is discussed.The results indicate that the cloud top of the target cloud began to rise 13 min after seeding;the target cloud echo strengthened 3dBz 19 min after seeding;the target cloud VIL increased from 2.5kg/m^2 to 3kg/m^2 25 min after seeding.The 10 min precipitation at three rainfall stations that the target cloud passed had the same increasing trend,and the analysis from the time and location indicates that these changes are associated with the rocket artificial precipitation.
