摘要
根据广西强对流天气的普查和统计分析,将全区日出现雷雨大风、冰雹总站次≥5的作为区域性的强对流天气过程。通过对1990～2001年共12a春季(2～5月)广西所出现的51次区域性强对流过程的环流形势场和对强对流天气有指示意义的一些物理量场的合成分析,得出了广西产生区域性强对流天气过程的环流特征和物理量的分布演变特征。
According to the general investigation and statistical analysis of strong convection weather in Guangxi, occasions in which hail and thunder storm accompanying by gale occurs a day for more than 5 times or in more than 5 weather stations is regarded as regional strong convection weather process. The synthesis analysis of the 33 regional strong convection weather processes in the 12 springs since 1990 to 2001 in terms of circumfluence field and some physical quantity fields with directing meaning to strong convection weather found out the characteristics of circumfluence characteristics and distribution evolvement of the regional strong convection weather in Guangxi.
