Abstract:
Using hail suppression sites in Yuxi City and Qujing City where hail storms frequently occur, two test sites were set in Jiangchuan District, Yuxi City and two others were respectively set in Malong County and Qilin District of Qujing City in 2015; and then two more test sites were set in Zhanyi District, Qujing City in 2016. Those 6 test sites were used to conduct a comparative experiment between the hail suppression operations using anti-aircraft artillery and rockets. The results show that both anti-aircraft artillery and rockets can be used to suppress the development of strong convective (hail) storm clouds, with an obvious effect about 10—15 minutes after the operations. However, as to relatively strong hailstorms, the anti-aircraft artillery proves to be much more effective in hail suppression.
