Color grade of weather forecast

The color grade of meteorological disaster early warning signal is blue-yellow-orange-red according to the degree of harm from low to high.

Meteorological disaster warning signals (hereinafter referred to as warning signals) are generally divided into 14 categories, generally divided into four grades: blue, yellow, orange and red. The color grade of meteorological disaster early warning signal is blue-yellow-orange-red according to the degree of harm from low to high. Blue indicates minor meteorological disasters, yellow indicates meteorological disasters that may have a certain impact on people's lives, orange indicates meteorological disasters that may have a greater impact on people's lives, and red indicates extreme meteorological disasters that may cause heavy casualties and property losses.

These color grades are to help the public better understand the severity of meteorological disasters and take corresponding preventive measures. For example, when receiving the yellow warning signal, people should pay attention to the weather changes and prepare for rain; When receiving the orange warning signal, people should avoid going out and try to stay indoors; After receiving red warning signal, people should immediately evacuate the dangerous area and look for a safe haven.

In a word, it is of great significance to know the color grade of meteorological disaster warning signals for ensuring the safety of people's lives and property. We should pay close attention to the weather forecast and the early warning information issued by the relevant departments, and take corresponding preventive measures according to the actual situation.

Regional characteristics of meteorological disaster early warning signals

Except Hongkong, Macau and Taiwan Province Province, the early warning management schemes in all parts of the country are basically the same; However, different provinces (cities, autonomous regions) have different standards for the same or different types of early warning: when a meteorological element constitutes a meteorological disaster in one place, it may not be a meteorological disaster in another place, which may be caused by different types and times of early warning regulations.

The warning standards of cold wave, frost and low temperature vary greatly from place to place. The meteorological departments of Hong Kong, Macao and Taiwan have an independent disaster response system. The following warning signals are common warning signals and standards in China. When the early warning comes into effect, please take the specific measures issued by the Meteorological Observatory as the standard, and take corresponding countermeasures according to the instructions of TV and radio.

In addition to the warning signals in the table below, there are other different early warnings in various places. 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.
