Early warning levels include

The warning level includes, in daily life, many people like to know the recent weather by watching some meteorological broadcasts, and the warning level is what we often call the warning of some meteorological disasters. Let's look at the early warning level, including it.

The warning level includes 1 meteorological disaster warning signal, which is generally divided into four levels (level IV, level III, level II and level I), representing average, heavy, serious and particularly serious respectively, and marked in Chinese and English, consistent with all emergency disposal levels and colors of the country.

1, fog warning signal. The fog warning signal is divided into three levels, which are indicated by yellow, orange and red respectively, and the fog red warning signal is the highest level in the fog warning signal.

2. Blizzard warning signal. Blizzard warning signal * * * is divided into four levels, which are represented by blue, yellow, orange and red respectively. Four kinds represent different snowfall and snowfall effects.

3. Hail warning signal. The hail warning signal is divided into two levels, which are represented by orange and red respectively. Among them, the orange warning signal of hail indicates that there may be hail with lightning weather within 6 hours.

4. Frost warning signal. Frost warning signals are divided into three levels, which are represented by blue, yellow and orange respectively.

The types of meteorological disaster warning signals have been increased from the original three to 1 1, and the familiar black typhoon warning signal will be withdrawn from the historical stage, while the first-class white typhoon warning signal will be retained in Guangdong (for the meteorological disaster warning signal system formulated and implemented in Guangdong Province, see "Guangdong Province Emergency Meteorological Disaster Warning Signal and Defense Guide"). )。 The newly added meteorological disaster warning signals are generally divided into four levels (IV, III, II and I), which respectively represent general, heavy, serious and particularly serious.

At the same time, it is marked in Chinese and English, which is consistent with all emergency treatment levels and colors in the country. The black warning signal of typhoon, rainstorm and cold will become history, with red as the highest level.

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

The warning level includes two high temperature warning levels.

The high temperature warning signal is divided into three levels, which are represented by yellow, orange and red respectively. Among them, the standard of high temperature yellow warning signal is: the daily maximum temperature is above 35℃ for three consecutive days; The standard of high temperature orange warning signal is: the maximum temperature rises above 37℃ within 24 hours; The standard of high temperature red warning signal is that the maximum temperature rises above 40℃ within 24 hours.

Meteorology, when the temperature is above 35℃, it can be called "high temperature weather", and if the highest temperature exceeds 35℃ for several days, it can be called "high temperature heat wave" weather. Generally speaking, there are usually two kinds of high temperature, one is dry heat and high temperature with high temperature and low humidity; The other is hot and humid, which is called "sauna day".

High temperature yellow warning signal standard: the daily maximum temperature will be above 35℃ for three consecutive days; High temperature orange warning signal standard: the maximum temperature will rise above 37℃ within 24 hours;

High temperature red warning signal standard: The maximum temperature will rise to above 40℃ within 24 hours.

Warm reminder of hot weather

1, when working outdoors in hot weather, take effective protective measures to avoid skin exposure to the sun for a long time, preferably with cold drinks.

Don't run in the sun in hot weather, and don't go to crowded places. Don't turn on the air conditioner immediately after returning to the room from the outside.

What is the warning level including 3 fogs?

Fog warning is divided into three levels, namely yellow, orange and red. Fog red warning is the highest level of fog warning. Before 20 13, the fog warning was only blue and yellow. With the development of social economy, the public's demand and standard for visibility forecast are also improving, and the early warning level needs to be more detailed. 20 13 added orange warning to the fog warning standard, and the latest revision of 20 14 added the fog red warning level.

As far as the Central Meteorological Observatory is concerned, the release of fog warning needs to follow the following standards:

The standard for issuing the red warning of fog is that it is estimated that in the next 24 hours, strong fog with visibility less than 200 meters may appear in parts of three or more provinces (autonomous regions and municipalities directly under the Central Government), and patch fog with visibility less than 50 meters (covering five or more adjacent national basic weather stations or national reference climate stations); Or it has already appeared and may continue.

The standard of orange fog warning is that fog with visibility less than 500 meters may appear in three or more provinces (autonomous regions and municipalities directly under the Central Government) within 24 hours, and patches with visibility less than 50 meters may appear (covering five or more adjacent national basic weather stations or national reference weather stations); Or it has already appeared and may continue.

The criteria for issuing yellow fog warning are: fog with visibility less than 1000m and patches with visibility less than 200m may appear in three or more provinces (autonomous regions and municipalities directly under the Central Government) within 24 hours (covering five or more adjacent national basic weather stations or national reference weather stations); Or it has already appeared and may continue.

However, the warning levels and release standards of fog issued by meteorological offices and stations affiliated to the competent meteorological departments of provinces (autonomous regions and municipalities directly under the Central Government) shall follow the warning release regulations of provinces (autonomous regions and municipalities directly under the Central Government).
