A Numerical Simulation of Hailstorm Accumulation Zone and Hail Formation
冰雹云中累积区与冰雹的形成的数值模拟研究

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.
