The following is an introduction of the warning signal by Anhui Meteorological Bureau, which may be helpful for the landlord to understand this thing.

In order to prevent and mitigate meteorological disasters, protect people's lives and the safety of the state, collectives and individuals' property, according to the Meteorological Law of People's Republic of China (PRC) and the Regulations on Meteorological Management of Anhui Province, combined with the actual situation of our province, the Anhui Meteorological Bureau and the Anhui Provincial Bureau of Radio, Film and Television jointly studied and formulated the Provisions on the Release of Meteorological Disaster Early Warning Signals in Anhui Province, which are hereby promulgated. All units shall, in accordance with the prescribed requirements, cooperate with each other and do a good job in the release of meteorological disaster warning signals.

First, the early warning signal of meteorological disasters in Anhui Province is the unified signal of our province's defense against meteorological disasters, and the early warning signals of meteorological disasters in various places must obey these provisions.

Two, Anhui meteorological disaster warning signal issued by the meteorological offices and stations affiliated to the competent meteorological departments at or above the county level, any organization or individual shall not be released to the public in any way. The release standards, grades and categories of meteorological disaster warning signals shall be implemented in accordance with the Guidelines for the Release and Defense of Meteorological Disaster Warning Signals in Anhui Province (annex 1).

3. The early warning signals issued by our province are tentatively classified into seven categories, such as typhoon, rainstorm, high temperature, cold wave, low temperature and cold, thunderstorm and gale, which are generally divided into four levels (IV, III, II and I). According to the severity and urgency of the disaster, the colors are basket, yellow, orange and red in turn, and they are marked in Chinese and English, representing ordinary, heavy, serious and super-serious respectively. The early warning signals issued by meteorological stations at all levels in the province must adopt a unified graphic library. When multiple meteorological disasters occur or forecast at the same time, multiple early warning signals should be issued at the same time according to the corresponding standards.

Question 6: Early warning levels are generally divided into meteorological disaster early warning signals, which are the early warning information released to the public by meteorological stations affiliated to meteorological authorities at all levels. Generally, it is divided into four levels, which are represented by blue, yellow, orange and red. Blue is the four-level warning, which is the lowest level warning. The blue weather warning signal indicates that meteorological disasters may cause general harm to the local area. According to the development of weather process, it will take some time for disasters to come, so emergency measures can be taken to prepare for disaster prevention and resilience. Red is the first-level warning and the highest-level warning. Red warning signal said that meteorological disasters are particularly serious, and the weather process will soon affect the local area, so measures should be taken to prevent disasters and avoid risks as soon as possible. Yellow and orange are warning signals of Grade III and Grade II respectively, indicating the severity of the disaster. The urgency of disasters and the development trend of disastrous weather are between blue and red warning, and the public should take corresponding disaster prevention measures according to different warning signals.

According to the different types of meteorological disasters, there are 14 kinds of meteorological disaster warning signals issued in China at present, which are typhoon, rainstorm, blizzard, cold wave, gale, sandstorm, high temperature, drought, lightning, hail, frost, fog, haze, road icing and so on.

Each disaster meteorology only issues the second, third and fourth warning signals according to its impact on the public and the degree of harm. Typhoon, rainstorm, blizzard, cold wave and gale are disasters with large scope and high frequency, and four-level early warning is issued, ranging from general blue to heavy yellow, severe orange and particularly severe red; Sandstorm, high temperature, lightning, fog, road icing and other disasters will only affect the public when they are serious, so yellow, orange and red warnings are issued, and there is no general blue warning; Drought and hail only issued two high-level warnings, orange and red, without general and more serious warnings; The smog only issued two levels of warning, yellow and orange, and there was no general level of blue and special severity level of red warning; Frost only issued three levels of warning: blue, yellow and orange, and there was no particularly serious red warning.

Question 7: First-class blue warning, second-class high temperature orange warning?

Question 8: Various color warning signals such as green warning, red warning and yellow warning.

The early warning signal consists of name, icon, standard and defense guide, and is divided into high temperature, road icing, haze, fog, frost, hail, lightning, drought, sandstorm, strong wind, cold wave, blizzard, rainstorm and typhoon. The level of early warning signals is generally divided into four levels according to the degree of harm, urgency and development trend that meteorological disasters may cause: level IV (general), level III (heavier), level II (severe) and level I (particularly serious), which are indicated by blue, yellow, orange and red in turn and marked in Chinese and English.
