Typhoon knowledge is popularized, and the top ten weather signs before the typhoon is registered (including, but not limited to)

In the summer, the typhoon in the coastal areas of China is rampant. How can we take precautions before the typhoon arrives and prevent it? The most basic thing is to judge whether the typhoon will come in the near future. China Rescue Equipment Co., Ltd. has compiled a number of weather conditions that are 2-3 days before the onset of the typhoon and observe the surrounding environment.
(1) Gao Yun appears: At the outermost edge of the typhoon is a cirrus cloud, a white plume, or a very high cloud. When this type of cloud appears in a certain direction, it gradually thickens and becomes a denser cirrus cloud. It is indicated that there may be a wind gradually approaching.
(2) Thunderstorm stops: In the summer, thunderstorms often occur in mountainous and basin areas every afternoon. If thunderstorms suddenly stop, it means that there may be a typhoon approaching.
(3) Visibility is good: Visibility is improved two or three days before the onset of the typhoon, and distant trees can be clearly seen.
(4) The sea and land breeze are not obvious: usually the daytime wind blows from the sea to the land, and blows from the land to the sea at night. It is called sea breeze and land breeze, but this phenomenon is not obvious in the days before the typhoon.
(5) Changlang: In the offshore areas, the waves are relatively stable due to the mild summer winds. However, when there are typhoons in the distance, the waves will tend to surge and gradually spread to the coast of Taiwan, with long waves.
(6) Haiming: As the typhoon approached, the long wave gradually increased and hit the coastal cliffs and buzzed. The east coast was often heard, and after about 3 hours the background winds would come.
(7) Showers stop and fall: When Gao Yun emerges, the clouds gradually decrease, and frequent showers stop falling. This is also a sign that the typhoon is approaching.
(8) Change in Wind Direction: Taiwan tends to use southwesterly winds in summer, but it is also gentler. However, if it changes to northeasterly winds, it means that the typhoon has gradually approached and has begun to be affected by the edge of the typhoon. After that, the wind speed will gradually increase.
(9) Special sunsets: When the typhoon struck on the 1st and 2nd days before the typhoon, several radiant red and blue rays of light were often sent out under the horizon of the west, and they were emitted to the top of the zenith, where they were symmetrical to the sun. This phenomenon is called anti-light.
(10) Air pressure reduction: According to the above phenomenon, if the air pressure is gradually reduced again, the display will enter the typhoon edge.
