How to distinguish warning levels?

How to distinguish several 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 saying about the division of grades. Describes how to distinguish alert levels.

What are the levels of early warning? 1 Meteorological disaster warning signals are generally divided into four levels (IV, III, II and I), which represent ordinary, heavy, serious and particularly serious respectively. They are marked in Chinese and English, which are consistent with all emergency disposal levels and colors in the country.

Meteorological disaster early warning signal (hereinafter referred to as early warning signal) refers to the early warning information released to the public by the meteorological offices and stations affiliated to the competent meteorological departments at all levels. Early warning signals are composed of names, icons, standards and defense guidelines, which are divided into typhoon, rainstorm, blizzard, cold wave, gale, sandstorm, high temperature, drought, lightning, hail, frost, fog, haze, road icing and so on.

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.

Weather forecast (measurement) or meteorological forecast (measurement) is to use modern science and technology to predict the state of the earth's atmosphere in a certain place in the future. Since prehistoric times, human beings have begun to predict the weather and arrange their work and life accordingly (such as agricultural production and military operations). ).

Today's weather forecast mainly uses collecting a large number of data (temperature, humidity, wind direction and speed, air pressure, etc.). ), and then use the current understanding of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of the atmospheric process and the fact that science has not fully understood the atmospheric process today, there will always be some errors in the weather forecast.

How to distinguish warning levels? 2 How are the weather forecast colors sorted by grades?

Blue, yellow, orange and red in turn.

The new version of meteorological disaster warning signal is generally divided into four levels (IV, III, II and I), which respectively represent general, serious, serious and particularly serious. Early warning signals are composed of names, icons, standards and defense guidelines, which are divided into typhoon, rainstorm, blizzard, cold wave, gale, sandstorm, high temperature, drought, lightning, hail, frost, fog, haze, road icing and so on.

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 wave has become history, and red is the highest level.

Provisions on requirements related to meteorological disaster early warning signals:

1, the state encourages relevant scientific research units, academic groups and individuals to study and discuss weather forecasting techniques and methods. Their conclusions and opinions on development and forecasting can be provided to local meteorological stations or published at weather forecasting seminars and other professional meetings sponsored by meteorological stations at all levels, but they shall not be publicly released in any form.

2. Short-term weather forecasts and severe weather warnings made by meteorological stations at all levels under the jurisdiction of the State Meteorological Administration can be released to the public. Long-term weather forecast is only for internal reference of people's governments at all levels, flood control and drought relief headquarters and relevant units, and is generally not published or reported publicly.

3. If it is necessary to publish or report publicly because of disaster prevention decision-making, it shall be approved by the State Meteorological Administration or the meteorological bureaus of relevant provinces (autonomous regions and municipalities directly under the Central Government).

What are the levels of early warning? 3. What colors do the weather warning signals have?

There are four kinds of weather warning signals: blue, yellow, orange and red, which respectively represent normal, severe, serious and particularly serious.

Meteorological warning level is an early warning level set according to the severity and urgency of disasters, which is expressed by specific signs.

Early warning signals are divided into eleven categories, such as typhoon, rainstorm, high temperature, cold wave, fog, thunderstorm and gale, gale, sandstorm, hail, blizzard and road icing.

According to the characteristics and early warning ability of different disasters, the early warning grades and standards of different disasters are determined.

When a variety of meteorological disasters occur or are expected to occur at the same time, a variety of early warning signals can be issued simultaneously according to the corresponding standards.

Regional characteristics of early warning signals:

Early warning management schemes are basically the same throughout the country. However, different provinces (municipalities and autonomous regions) have different standards for the same or different types of early warning.

A meteorological element constitutes a meteorological disaster in one place, but it is not necessarily a meteorological disaster in another place, which may be caused by the different types and times of early warning regulations. The warning standards of cold wave, frost and low temperature vary greatly from place to place.

When the early warning comes into effect, the specific measures shall be subject to those issued by the Meteorological Observatory, and corresponding countermeasures shall be taken according to the instructions of television and radio.

In addition to early warning signals, there are other different early warning signals in various places, such as cold wave warning (Guangdong, etc.). ), snow disaster warning (Qinghai, etc. ), early warning signals such as heavy snow warning and road ice and snow warning (Northeast China).

Meteorological stations in coastal areas will also issue marine meteorological warnings specifically for marine areas. Please refer to the website of the meteorological department of the province (municipality directly under the central government, autonomous region) for specific meanings, countermeasures and specific meanings.

In addition to meteorological warning signals, meteorological stations may also issue environmental, geological, forest, marine, health and other types of warning signals, because many areas of early warning release platforms are in meteorological stations.
