摘要

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