Numerical Simulation of the Accumulation Zones and Hail Growth Trajectories in Hailstorms
含水量累积区与冰雹增长行为之数值模拟

A three-dimensional hailstorm model and a three-dimensional Lagrange hail growth model were used to do further study of a hailstorm occurring in Xunyi,Shaanxi Province,on 28 July 1997,which was found out that there existed an accumulation zone in the storm in earlier researches.The modeling results showed that:(1) embryos were formed in the accumulation zone,and the accumulation zone was also the area where embryos accreted in their early stages,however,it was not the main growth area of these embryos.(2) O...
