ABSTRACT: This research uses the 59th-70th national emergency early warning
information release monthly report data of China to study the total number of
emergency early warnings in 2021, the general situation of early warning
categories and regional distribution differences. The results show that: 1) there
are 387,075 early warning information in China in 2021, and the early warning
has obvious seasonality. 2) The issuance of early warnings is obviously related to the seasons, and the issuance of early
warnings varies from month to month. The issuance of one kind of early warning
can easily lead to the issuance of another kind of early warning, that
is, the early warnings are closely related, and some specific disasters are
easy to cause secondary disasters. 3) There are differences in the number of early
warnings in each province. 4) The reason for the peak of early warnings in July
and the large proportion of red early warnings in Henan Province is the sudden
heavy rainstorm in Henan Province in July; the physical mechanism of this heavy
rainstorm is sufficient water vapor, strong
uplifting movement and stable situation and a long existence time.
