The mesoscale convective complex(MCC) in the south of Shanxi and the rainstorm cloud clusters in the north of Shanxi on August 11, 2010 are comparatively analyzed by using T639 1°×1° reanalysis data, FY-2 infrared satellite image and infrared black body temperature (TBB) data, lightning data and total column water vapor data. Itdemonstrate that rainstorm area in the north of Shanxi was causedby the generation, development, merger of 6 meso-β-scale convective cloud clusters, and the south regional rainstorm happened with the generation, development and eastward movement of the mesoscale convective complex (MCC). The analyzed results indicate that: (1) The northern rainstromcloud cluster developedin the south of warm shear line on 850 hPa, and mergednear by shear lineon surface. At the same time, the southern MCC was merged by 3 meso-β-scale convective cloud clusters, which developed on the weather-scale shear lineon 700 hPa. In the process of MCC development and maturity stage, meso-α-scale convective cloud clusters moved east along the warm shear lineon 925 hPa, and intheprocess of MCC weakening, meso-α-scale convective cloud clusters moved south with the southward movementof subtropical high belt. (2) With the northwestward advance of the subtropical high during thesame rainstorm, MCC developed in the weak baroclinic environment of the 5 880 gpm region, and in the anticyclone north of high onupper levels; rainstorm cloud clusters tended to develop in the strong baroclinic environment of  5 840 gpm region, and in the the right of the upper jet stream entrance area. (3) As a large scale mesoscale convective system, MCC required more energy of high temperature and high humidity than general rainstorm cloud clustersinlower levers, and deeper vertical structure of high humidity, high energy tongue and high temperature. (4) The negative cloud-to-ground lightning appeared in the area which was influenced by the southern MCC and near the 5 880 gpm region; the positive cloud-to-ground lightning appeared in the area which was influenced by the northern rainstromcloud clusters and near the 5 840 gpm region. The time of the begin of lightning and the appearanceof the lightning peak was more earlierthan the time of rainfall and the appearance of the rain intensity peak in the backgroud of general rainstorm cloud clusters, comparing with the banckground of MCC. (5) The northern rainstorm cloud clusters developed in the area of high gradient of vertically integrated water content and on the front of water vapor; the southern MCC developed in the area of high value of total column water vapor, thesouth of the water vapor front. There is  ahead 36 h  to exactly forecast  the total column water vapor data of the rainstorm process on August 11, which showsa significant indication to rainstorm area.
