THE MECHANISM OF GENERATION OF HEAVY RAIN CLOUD CLUSTER AND THE DEVELOPMENT OF THE LOW PRESSURE SYSTEM IN MEI-YU PERIOD

Dong Xiaomin Wen Xingqin (Jianggu Meteorological Bureau)  
Two cases of heavy rains in mei-yu period have been studied. It is found that: (1) the confluent region of the cloud line in a north-to-south direction ahead of the upper westerly trough and the cloud line in a west-to-east direction beside the subtropical high is closely related to the maximum wind speed core on upper and lower jet stream axes, and this confluent region contributes to the generation of the heavy rain cloud cluster; and (2) in the mei-yu frontal zone, the positive vorticity advection, divergence and warm moist air advection decrease with height ahead of the trough in the upper troposphere, while the strong convergence of low pressure and warm moist air advection increase with height in the lower troposphere; we found that this configuration contributes to the formation and development of the frontal cyclone.
