ABSTRACT: To analyze
a new heavy rain case over China during the year 2022, by using
the data from NCC-CMA and NCEP, a heavy rain weather process in most areas of China
from July 26 to 30, 2022 was analyzed. Synoptic methods were used in this research and results show that under the influence of low vortex
and wind shear, the abundant water vapor supply brought by the southeast airflow
in the lower level and the lifting of the Taihang Mountain, heavy rain weather occurred
in the northern part of Henan, China. In the west of Liaoning and Jilin, the rainfall
process had the characteristics of frontal rainfall and the stable precipitation
resulted in heavy rain weather. To sum up, the rainfall process was mainly affected
by the upper-level trough, low-level wind shear and low-level jet.
