A numerical experiment on a heavy rain process occurred in the last dekad of June in 1998 is conducted by means of the limited area prediction model of the National Meteorological Center. The formation causes of the process are discussed through analyzing the winds, water vapor, vertical velocity and other elements. The results show that the main synoptic scale weather systems causing the heavy rain are the Southwest low-level jet and a shear line between dry air from north and warm and moist air from /southwest in the middle and lower reaches of the Changjiang River. The mesoscale weather systems moving along the shear line play a very important role in precipitation reinforcement
