| Abstract: | The three dimensional storm cloud is recognized with the CAPPI data and its structural parameter is calculated. The echoes of the single and complex storm are tracked with the integrated method of the centroid trace and unchanged moment and they are predicted by the least square extrapolation. In addition, according to the WSD 88D algorithm of hail storm and the basic of its structure, the automatic recognition system of hail cloud is set up on the Windows 98. Having checked the 11 data of the severe convective storm in one year, the results show that the 82% hail cloud are recognized. There are many man machine interfaces in the system, which are convenient for the uses. |
