How many kinds of meteorological disaster warning signals are there?

There are 16 kinds of disaster meteorological warning signals, namely: typhoon, rainstorm, blizzard, cold wave, gale, sandstorm, high temperature, drought, lightning, hail, frost, fog, haze, road icing, thunderstorm and gale, forest fire.

1. 1. Water factors: flood, waterlogging (waterlogging), wet damage, ice, freezing damage and grassland white damage caused by excessive water; Atmospheric drought, soil drought, crop physiological drought and grassland black disaster caused by serious water shortage. ?

2. Second, the temperature factor: it is manifested as "high temperature unreality" and "high temperature ripening" of crops caused by excessive temperature, sudden heat after rain, heat wave and heatstroke; Frostbite, freezing injury, frost and frostbite caused by low temperature. ?

3. The third is the light factor: it is manifested as burns and sunburns caused by excessive light; Yin loss caused by serious lack of light. ?

4. The fourth factor is snow and ice: it is manifested by blizzard, icing, freezing and thawing, and returning to pulp. ?

5. Fifth, other factors: hail, strong wind, lightning and fog disasters. ?

6. Sixth, composite factors: sandstorm, continuous rain, dry and hot wind, foehn wind, typhoon and snowstorm.
