摘　　要：Based on weather radar observation data,development and evolution characteristics of radar intensity echoes PPI and RHI of one ha shooting weather process in the Fifth Regiment of the First Division on May 24,2011 were analyzed. The results showed that local thermal forcin effect was obvious. The Fifth Regiment is close to mountain region,and the supplement of downward cold air from the mountain region was th most direct,and the supplement efficiency was the highest,which was main cause for the hail shooting generated by local severe convective weath er in west area of south Xinjiang. In the hail weather development process,vault( weak echo zone),front suspending echo and echo wall of supe cell on radar echo showed that airflow activity was strong in windstorm,which had an important indication significance for discrimination of ha cloud. The research could provide reference basis for conducting artificial hail suppression and proximity prediction of severe convective weather i reclamation area in the future,and had certain indication significance and better application value.Based on weather radar observation data,development and evolution characteristics of radar intensity echoes PPI and RHI of one ha shooting weather process in the Fifth Regiment of the First Division on May 24,2011 were analyzed.
