A comprehensive analysis of rainstorm weather process and hail with gale weather process is made on the basis of breaking up evolving theory and by using the breaking up evolving figure and v 3θfigure , and the results indicate the great suggestive role of breaking up evolving theory in the forecast of rainstorm weather and hail weather with gale.

Aerocraft is easy to impact with hailstone and may cause serious damages during its flight,so it′s necessary to investigate hail impact on aerocraft by trial system.

The methods of speedup are proposed under the limitation of the strength of hailstone pill.

The hailstone impacting test system is constructed basing on the theory of air gun which energy is offered by compressed air.

Echo characteristics,circulation background and environment variables during a hailstorm in Akesu were analyzed by using basic CINRAD/CC data and its production.

The hailstorm occurred on July 6 to 8,2003 over the northeast of Qinghai-Xizang plateau was simulated by using MM5,and its meso-scale circulation background and local convective cells characteristics were analyzed based on simulated data.
