With data of T639L19 1°×1° analysis field, FY-2 infrared cloud and infrared radiation brightness temperature(TBB), doppler radar, air vapor content, and so on, the multi-scale feature of the regional rainstorm occurred in Shanxi territory from 2 to 3 July 2011 was analysed. The results show that: (1) The subtropical high moves up northward, the southwest warm-wet air flow enhances, the cold air behind the northeast cold vortex moves down southward, the frontogenesis in the mid-north part of Shanxi are large-scale circulation features of the regional rainstorm. (2) The rainstorm in the middle of Shanxi was created by two β mesoscale convective cloud cluster, and triggered the convection developing nearby the two mesoscale shear line on the boundary layer, and formed two rainstorm centers; While, the rainstorm in the south of Shanxi was created by eight mesoscale convective cloud clusters, developed and combined, and triggered the convection developing nearby the α mesoscale herringbone shear line on the boundary layer. The four γ mesoscale cyclone on the α mesoscale herringbone shear cloud system were the direct reason of the occurrence of the local heavy rainstorm and super rainstorm; The black body brightness temperature area ≤-53℃ advanced the area where the doppler radar herringbone shear cloud system reflectivity gene ≥35 dBz. (3) During the early-middle period of precipitation, the convective cloud cluster combined led to the appearance of cloud-to-ground lightning frequency peak value and precipitation peak value. And the cloud-to-ground lightning frequency peak value appeared 12~18 minutes earlier than the precipitation peak value. (4) The rainstorm of middle part occurred in the area of air vapor content spatial distribution map, where the horizontal grads big value area overlapped with the boundary layer shear line. While, the rainstorm of south part occurred in the area of air vapor content spatial distribution map, where the high humidity area was at a distance of 0.5~1.0 latitude and longitude from south of the horizontal grads big value area, overlapped with the boundary layer herringbone shear; Both the forming time of the air vapor content spatial distribution map horizontal grads big value area and the forming time of the boundary layer shear line were 12 h earlier than the arising of rainstorm.
