[Method] Using the principle of lizi synoptic meteorology, 13 regional rainstorm weather processes occurred in Hunan Province in 2010 were analyzed. [Result] Thirteen rainstorms are all closely related to self-organization convergent airflow, rainstorm is the inevitable result after the outbreak of self-organization convergent airflow. The inoculation area of self-organization convergent airflow is accorded with the occurrence area of rain- storm in the next 12-36 h; once the inoculation area of self-organization convergent airflow disappears, there will be no regional rainstorm in the next 12-36 h; the inoc- ulation area of self-organization convergent airflow is produced in the convergence domain of large scale of southern and northern lizi pair. [Conclusion] The existence of southern and northern lizi pair can be used as the short-term forecast model of regional rainstorm during flood season.展开更多
