Interpretation of early warning

Early warning is called Early-Warning in English, which can be interpreted as: before disasters or disasters and other dangers that need to be guarded against occur, according to the laws summarized in the past or possible precursors observed, an emergency signal is sent to the relevant departments to report the dangerous situation, so as to avoid the occurrence of hazards without knowing or being prepared enough, and minimize the losses caused by hazards.

Warning level of major meteorological disasters:

According to the standard of disastrous weather and climate intensity and the degree of casualties and property losses caused by major meteorological disasters, major meteorological disasters are identified as four early warning levels: general (IV), heavy (III), serious (II) and particularly serious (I):

Level 1 early warning:

In the administrative area of a province (autonomous region or municipality) or in the administrative areas of several provinces, the meteorological stations subordinate to the competent meteorological departments forecast the occurrence of disastrous weather and climate processes, and the intensity reached the extreme disastrous weather and climate standards formulated by the competent meteorological departments of the State Council. Or the meteorological level of geological disasters reaches level 5, and the meteorological level of forest (grassland) fire danger reaches level 5.

Secondary warning:

Its intensity reaches the disastrous weather and climate standard formulated by the competent meteorological department of the State Council. Or the meteorological grade of geological disasters reaches Grade 4, and the forest (grassland) fire risk grade reaches Grade 4.

Three-level warning:

Its intensity reaches the disastrous weather and climate standard formulated by the competent meteorological department of the State Council. Or the meteorological grade of geological disasters reaches Grade III, and the meteorological grade of forest (grassland) fire danger reaches Grade III.

ⅳ warning:

Its intensity reaches the disastrous weather and climate standard formulated by the competent meteorological department of the State Council, or the meteorological grade of geological disasters reaches Grade II, and the meteorological grade of forest (grassland) fire danger reaches Grade II.
