%X An
extensive rainfall occurred in central and eastern China during 23-24 April,
2021. This research mainly uses the reanalysis data of NCEP/NCAR every 6 hours

reason for this precipitation process is the shear formed between the cold air
and the warm and humid air flow in the southwest. The low temperature on the
ground allows the warm and humid air flow to lift up to form precipitation. The
shear system is strengthened to a low vortex, which greatly strengthens the
vertical ascent movement. Good water vapor and dynamic conditions form a large range
of heavy rainfall.
