What are the early warnings for typhoon prevention?

? Typhoon is a natural disaster phenomenon. He also has achievements. China Meteorological Bureau classifies typhoon signals into four grades, including blue, yellow, orange and red, and the four colors also represent four winds with different intensities.

? If the warning signal is blue, it will be dwarfed by typhoons of other colors. Its level is the weakest, the lowest and the least windy. The weather bureau set it at about level 6. A typhoon of magnitude 6 is nothing to us, because it is caused by tropical pressure. You may feel a little hot when it blows in hot summer.

? The yellow warning typhoon is a little risky. Its average wind power is eight, and its speed reaches tens of meters per second. At this speed, the long branches on the tree may be blown off and the sea will be rough. If this kind of wind blows in autumn, you need to take home the clothes that are drying outside at home in time and close the windows to avoid blowing things at home.

? Those rated orange are more dangerous. More aggressive than Huang, slightly stout trees are likely to be blown down by the wind. The waves on the sea surface are not only described by surging waves. If it reaches the orange level, the Meteorological Bureau will generally remind households to pay attention to doors and windows. People who live in houses in the old city need to pay more attention, because it is an old house, and the building is not as good as that just started, which will have greater hidden dangers. People who like high-altitude outdoor need to pay attention to their own safety, because danger is always around, and they must not be taken lightly. Houses prone to power failure need to be powered off in time.

? Not to mention the wind with a red warning. It has the strongest wind and can uproot houses. At this time, some schools will close classes and live in very stable houses. This wind may also cause flash floods. Families in low-lying areas will move to safe places with their belongings, and the docked ships need to take timely preventive measures. The country will also take immediate measures to ensure our safety.

Don't underestimate my typhoon, because sometimes it will take people's lives. In times of crisis, always pay attention to protect yourself!
