Take advantage of average black body temperature data of FY meteorological satellite, altitude and surface weather observations, precipitation data of 85 meteorological stations in Guizhou Province, and hourly precipitation data of township automatic observation station during 2010.Censused of mesoscale convective complexes (MCC) in the eastern mountain of Yunnan-Guizhou Plateau, counted and analyzed its spatial and temporal characteristics, strength characteristics, life history, moving path, its precipitation distribution and intensity characteristics.The results indicate that, MCC in the eastern mountain of Yunnan-Guizhou Plateau in summer used to appear from May to July, formation time is from 19:00 to 03:00 the next day, its life history are generally more than 8 hours, newborn convective clouds which formed MCC generate in 13:00-18:00, its initial source area in western of Guizhou (103°-E105.6°E, 25°-N27.5°N).Vortex in Guizhou western edge is the direct influence system which cause convective cloud occur frequently.Maximum precipitation of MCC is mainly concentrated in the northwest and the northeast quadrant, and the distance to center of MCC is less than 3 latitude or longitude.Mountain short-term heavy precipitation are occurred mainly during the mature stage of MCC, and brightness temperature below -70℃.
