Abstract:
A ground precipitation enhancement was conducted on 28 September 2014 in Shandong. By means of CINRA radar and radiosonde data and 10min 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 3 dBz 19 min after seeding; the target cloud VIL increased from 2.5 kg/m2 to 3 kg/m2 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.
