In life, we often see early warning messages about various colors in the weather forecast information, but most people don't know what the early warning of different colors means? What is the difference between different color warnings? What should we do to ensure our own safety when encountering different color warnings? This article brings you the meaning and difference of different color warning. Let's learn about the next step.
Today, we spend three minutes trying to figure out the knowledge that is not uncommon. If you see similar information in the future, you can achieve the effect of simultaneous interpretation.
1. Rainstorm warning, I can understand Chinese characters. What does color mean?
Before the rainstorm, the meteorological department will issue early warning signals to the society, which are divided into four levels, which are represented by blue, yellow, orange and red in order from weak to strong.
2. Since there are four different levels of early warning, what is the difference?
The blue rainstorm warning is that the rainfall will reach or has reached more than 50mm within 12 hours, and the rainfall may continue.
The Yellow rainstorm warning is that the rainfall will reach or has reached more than 50mm within 6 hours, and the rainfall may continue.
The orange rainstorm warning is that the rainfall will reach or has reached more than 50mm within 3 hours, and the rainfall may continue.
The Red Rainstorm warning is that the rainfall will reach or has reached more than 100mm within 3 hours, and the rainfall may continue.
From the simplest mathematical point of view, the power of each level is almost twice that of the previous level.
3. Keep it simple. Keep it simple
Is there an easier and more intuitive way to understand? Yes, but the terminology is too professional, and the rainfall can not be unified according to different terrain and conditions. In fact, it's most reliable for me to tell you what to do directly. The following is the level IV rainstorm warning, layer by layer defense Guide:

4. One free knowledge point: 'gust'
Like Britain and the United States, 'gusts' always appear with' rainstorms', and they are inseparable friends. " Gust 'is a meteorological term, which refers to the sudden change of wind speed in a short time. Gust level 5 refers to the gust's wind strength reaching level 5.
How is the level and power of gusts reflected? In fact, everyone should have learned it in primary school. Let's review the old and know the new in the following ways:
Eh? Shouldn't the maximum wind be force 12? Why don't you write when the wind is above level 10?
