The official names of these early warning icons are meteorological early warning signals, which generally have four color levels: blue, yellow, orange and red, and their severity increases in turn, indicating ordinary, heavy, serious and particularly serious respectively. Blue is the lowest level warning, and red is the highest level warning.

Blue warning signal of blizzard: 12 hours, the snowfall will reach more than 4 mm, or it will reach more than 4 mm and continue to snow, which may affect traffic or agriculture and animal husbandry.

Typhoon blue warning signal: it may or may have been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 6, or the gust is above 8, and it may continue.

Blue warning signal of thunderstorm and gale: it may be affected by thunderstorm and gale within 6 hours, with an average wind force of above 6 or a gust of above 7 accompanied by lightning; Or it has been affected by thunderstorms and strong winds, and the average wind force reaches 6-7, or the gust of 7-8 is accompanied by lightning and may continue.

Blue rainstorm warning signal: 12 hours, the rainfall will reach more than 50 mm, or it has reached more than 50 mm, and the rainfall may continue.

Specifically, among these warnings, the most serious one is red. If the Meteorological Observatory issues a red warning, the TV broadcast will generally notify the suspension of classes and classes. In different fields, different levels of early warning have specific standards. For example, the "blue rainstorm warning" we often hear is the forecast issued when the rainfall exceeds 50 mm within 12 hours; Accordingly, the yellow warning is to reach the same precipitation within 6 hours; Orange, within 3 hours; The highest level of red will only be released when the rainfall reaches 100 mm within 3 hours.

Similarly, we look at the high temperature warning that is often heard in the weather forecast. Yellow means 35 degrees Celsius and orange means 37 degrees Celsius. When the red high temperature warning is issued, the temperature will reach or exceed 40 degrees Celsius! This method of marking colors according to grade distribution is very vivid to ordinary people, and it is easy to know the severity of disasters, and it is more convenient to take corresponding countermeasures.

But this kind of warning can't be released casually, and the relevant meteorological agencies at or above the county level are qualified, which ensures the authority of the warning, so as to avoid spreading "rumors" everywhere and causing panic! Now, do you know the meaning of each color warning?
