How to distinguish the levels of early warning?
How to distinguish the levels of early warning. Early warning generally represents the severity of what may happen, and different colors of early warning also represent different levels. , there is a certain explanation for the division of levels. Let me introduce to you how to distinguish the levels of early warning. How to distinguish the levels of early warning 1
Meteorological disaster early warning signals are generally divided into four levels (levels IV, III, II, and I): blue, yellow, orange, and red, which represent general and relatively severe levels respectively. Severe, serious and particularly serious, marked in both Chinese and English, consistent with all national emergency response levels and colors.
Meteorological disaster early warning signals (hereinafter referred to as early warning signals) refer to meteorological authorities at all levels Warning information issued by affiliated meteorological stations to the public. Early warning signals consist of names, icons, standards and defense guidelines, and are divided into typhoon, heavy rain, blizzard, cold wave, strong wind, sandstorm, high temperature, drought, thunder and lightning, hail, frost, heavy fog, haze, road ice, etc.
1. Heavy fog warning signal. The heavy fog warning signal is divided into three levels, represented by yellow, orange and red respectively. The red fog warning signal is the highest level among the heavy fog warning signals.
2. Blizzard warning signal. Blizzard warning signals are divided into four levels, represented by blue, yellow, orange and red respectively. Four represent different snowfall amounts and snowfall effects.
3. Hail warning signal. Hail warning signals are divided into two levels, represented by orange and red respectively. Among them, the orange hail warning signal indicates that hail accompanied by thunder and lightning may occur within 6 hours.
4. Frost warning signal. Frost warning signals are divided into three levels, represented by blue, yellow and orange respectively.
Weather forecast (measurement) or meteorological forecast (measurement) is the use of modern science and technology to predict the state of the earth's atmosphere at a certain location in the future. Since prehistoric times, humans have begun to predict the weather to arrange their work and life accordingly (such as agricultural production, military operations, etc.).
Today’s weather forecasting mainly uses the collection of large amounts of data (temperature, humidity, wind direction and speed, air pressure, etc.), and then uses the current understanding of atmospheric processes (meteorology) to determine future air changes. Due to the chaos of atmospheric processes and the fact that today's science does not finally have a thorough understanding of atmospheric processes, weather forecasts will always have a certain amount of error.

How are the weather forecast colors ranked by level
The order is blue, yellow, orange, and red.
The new version of meteorological disaster early warning signals is generally divided into four levels (levels IV, III, II, and I): blue, yellow, orange, and red, representing general, relatively serious, serious, and extremely serious respectively. Early warning signals consist of names, icons, standards and defense guidelines, and are divided into typhoon, heavy rain, blizzard, cold wave, strong wind, sandstorm, high temperature, drought, thunder and lightning, hail, frost, heavy fog, haze, road ice, etc.
It is also marked in Chinese and English, consistent with all emergency response levels and colors of the country. The black warning signals of typhoon, heavy rain and cold warning signals have become history, with red as the highest level.
Relevant requirements for meteorological disaster early warning signals:
1. The state encourages relevant scientific research institutions, academic groups and individuals to research and explore weather forecasting technologies and methods. The conclusions and opinions they draw when developing forecasts can be provided to local meteorological stations or published at weather forecast seminars and other professional meetings hosted by meteorological stations at all levels, but they are not allowed to be publicly released in any form.
2. Short-term weather forecasts and severe weather warnings produced by meteorological stations at all levels under the jurisdiction of the National Meteorological Administration can be released to the public. Long-term weather forecasts are only for internal reference of people's governments at all levels, flood control and drought relief headquarters and relevant units, and are generally not publicly released or reported.
3. If it is necessary to publicly release or report due to disaster prevention decision-making, it should be approved by the National Meteorological Administration or the relevant provincial (autonomous region, municipality) meteorological bureau. How to distinguish the levels of early warning 3
What are the colors of weather warning signals and what levels they represent?
There are four types of weather warning signals: blue, yellow, orange and red. The colors represent average, severe, serious and extremely serious respectively.
The weather warning level is a warning level set according to the severity and urgency of the disaster and represented by a specific logo.
Early warning signals are divided into eleven categories: typhoon, heavy rain, high temperature, cold wave, heavy fog, thunderstorm, gale, sandstorm, hail, snowstorm, ice accumulation on roads, etc.
Based on different disaster characteristics, early warning capabilities, etc., determine the early warning classification and standards for different disaster types.
When multiple meteorological disasters occur or are forecast to occur at the same time, multiple early warning signals can be issued simultaneously according to corresponding standards.
Regional characteristics of early warning signals:
Early warning management plans are generally the same across the country. However, different provinces (municipalities, autonomous regions) also have different standards for the same or different early warning types.
When a meteorological element constitutes a meteorological disaster in one place, it may not necessarily be a meteorological disaster in another place. This may be caused by the different types and times of early warning regulations. Cold wave, frost, and low temperature warning standards vary greatly from place to place.
When the warning takes effect, the specific measures issued by the meteorological station shall prevail, and corresponding countermeasures shall be taken according to instructions such as television and radio.
In addition to early warning signals, there are other different early warnings in various places, such as cold warning (Guangdong, etc.), snow disaster warning (Qinghai, etc.), heavy snow warning, road ice and snow warning (Northeast China) and other early warning signals.
Meteorological stations in coastal areas will also issue marine weather warnings specifically for marine areas. Please check the provincial (municipality, autonomous region) meteorological department website for specific response measures and specific meanings.
In addition to meteorological warning signals, since the warning issuing platform in many areas is at the meteorological observatory, the meteorological observatory may also issue environmental, geological, forest, ocean, health and other types of early warning signals.
