What are the signs before the typhoon lands?

There will be many conditions in the climate two or three days before the typhoon comes. The first is the appearance of high clouds, because at the outermost edge of the typhoon are cirrus clouds, very high clouds with white feathers or ponytails. When such a cloud appears in a certain direction and gradually thickens into a dense cirrostratus, it indicates that there may be a typhoon approaching. Then there will be showers stopping. For example, when high clouds appear, the clouds become denser and lower, and showers often stop, which may also be a sign of typhoon approaching.

The second is that the thunderstorm suddenly stops. In summer, there are often thunderstorms in Wenzhou every afternoon. If the thunderstorm stops suddenly, it means that there may be a typhoon approaching. Moreover, two or three days before the typhoon came, the visibility improved, and mountains and trees in the distance could be seen clearly. And the land and sea breeze will not be obvious. For example, the wind blows from the sea to the land during the day and from the land to the sea at night, which is called sea breeze and land breeze, but this phenomenon is not obvious a few days before the typhoon.

When the typhoon approaches, there will be the sound of the sea. For example, the long wave is getting bigger and higher, hitting the coastal cliffs and making a roar, which is often heard on the eastern coast. After that, the typhoon will come in about 3 hours. Moreover, there will be sudden changes in wind direction, for example, the southwest wind changes to the northeast wind, indicating that the typhoon is approaching and has begun to be affected by the edge of the typhoon, and then the wind speed will gradually increase.

There will be a special sunset glow. For example, a day or two before a typhoon strikes, when the sun goes down, several beautiful radial red and blue rays often shoot from the western horizon to the zenith, and then converge at the symmetry between the east and the sun. This phenomenon is called anti-twilight. With the decrease of air pressure, the human body feels uncomfortable. According to the above phenomenon, if the air pressure is gradually reduced, it means that it will enter the edge of the typhoon.
