ABSTRACT: To learn more about the unusually heavy rainfall in central China, this
research uses the monthly climatic data, weather map information and US NCEP
re-analysis data to analyze the atmospheric circulation, precipitation and
weather situation of this extreme precipitation weather process in Henan during
July 17-22, 2021. The results show that the precipitation process is affected
by the joint action of the subtropical high, the continental high, the low
vortex, the low-level jet, the typhoon “In-fa” and other multi-scale systems in
the middle and low latitudes. This precipitation process was also affected by
the topographic uplift and blocking of Taihang Mountain and Funiu Mountain.
