TL;DRAbstract
In order to research mesoscale and microscale structural characteristics of rainstorm in North China, a rainstorm case happening on 22-24 July 2005 in North China is selected. Characteristics of weather situation, water vapor transport, atmospheric stability and clouds field were analyzed in detail by using 1°×1° NCEP reanalysis data and TBB infrared data of FY2C satellite with 0.05°×0.05° resolution. The research results show that this rainstorm process is caused by influence of interaction between landing typhoon and westerly trough. Westerly jet flow behind upper trough stretch to the north of North China, and low level south-east jet flow lie in the east of North China, which is favorable to forming of low-level convergence and high-level divergence. Indian monsoon and South China Sea summer monsoon play important role in low-level water vapor northward transport into North China, and south-east jet flow existing in the west of subtropical high also transport water vapor partly.
