| 摘 要： | 应用三维冰雹云模式对陕西旬邑地区的一次降雹过程进行模拟,结果表明:冰雹云中存在过冷雨水的累积区,其出现在最大上升气流之上,其中累积的过冷雨水含量随着云的发展而变化.冰雹生长在此累积区内.催化试验结果表明,在过冷雨水的累积区内播撒AgI粒子能取得较好的防雹效果.

| Abstract: | Using a 3D cloud model, a hailstorm occurring in Xunyi of Shaanxi Province on July 28, 1997 is simulated. It shows that there is an accumulation zone of super-cooled rainwater in the hailstorm. Amount of super-cooled rainwater (SCR) is accumulated above the position of the maximum updraft and changes with time. The seeding experiment shows that AgI seeding in the accumulation zone can suppress hail formation. |
