摘要
防雹效果检验问题仍然是人影工作的技术难题。针对2006年4月12日龙岩市长汀防雹作业过程,利用实施防雹作业的一个单体作业前后回波特征变化和同时出现的两个未作业单体自然发展情况进行对比分析,认为实施火箭防雹作业后效果明显,强回波中心逐渐减弱、回波面积加大并未出现冰雹。有效地保护了下游区域免遭冰雹袭击。
The seeding effectiveness of hail suppression operations is still an arduous problem in the weather modification filed. Taking the hail suppression operation on 12 April 2006 as an example, a comparative analysis is made of the radar echo variation of a cloud cell before and after the operation and the echoes of two unseeded cloud cells occurred at the same time. The results indicate that the operation show apparent effectiveness after the suppression operations： the echo-center gradually weakened, echo area increased, and no hail appeared.
