With 85.5GHz microwave images of Tropical Rainfall Measuring Mission(TRMM) Satellite, which has good ability to monitor convective heavy rainfall, and GMS satellite infrared images in 1h interval, the mesoscale convective systems in Yangtze river basin during July 20～25, 1998 was revealed and analyzed. The relationship between the distribution of heavy rainfall and the blackbody temperature(TBB) of GMS satellite infrared images was examined. The results suggest that the mesoscale features of the heavy rainfall was outstanding, and the maximum rainfall peak took place at the time when the MCS just developed to the meso-β scale. The diagnosis of the large-scale environment suggested that the thermal and dynamic conditions were favorable to the development of the mesoscale convective systems in the Yangtze River basin.
