摘要
利用常规气象资料和T213数值预报产品,对2003年7月22日发生在宁南山区的雹暴天气进行了天气学成因分析,并对成雹的物理机制、大气层结稳定度等方面进行了探讨.通过对T213数值预报产品应用分析发现:该产品趋势预报与宁夏降水有较好的对应关系,其物理量场对宁夏南部山区强对流天气的发生发展具有较好的指示意义.
The formation of hailstorm taken place in the mountainous area in south part of Ningxia was analyzed in the article by using the regular meteorological data and T213 numerical forecast products, and the physical principle and the stability of atmosphere in the hailstorm＇s forming process were also discussed. The analysis on the application of T213 numerical forecast products indicated that T213＇s trend forecast product had a good relationship with the rainfall taken place in Ningxia, and its physical field had a good indication to the development of the severe convection weather in Ningxia.
