| Abstract: | Aheavy precipitation system occurring in the eastern plain of Hebei province insummer is analvsed based on the detail data. Evolution andfine structure of the meso-ascale convective systern are studied. And the physical mechanism of warm regionsforming in this system is investigated. The results show that the interaction betweendifferent scale systems has great effects on the event. |

| Keywords: | Meso-ascale convective system Arc cloud line Symmetry instability |
