A typhoon is also a cyclone, but it is a cyclone produced in tropical areas. When a cyclone is generated on the tropical or subtropical ocean surface, it develops and strengthens continuously, forming a typhoon. The center of the typhoon is called the eye of the typhoon. (1) The typhoon eye is a warm core axis, and the temperature in the eye area is much higher than the surrounding area. The stronger the tropical cyclone, the more obvious the warm heart in the eye area. The warm core structure of tropical cyclones appears in the development stage and reaches its strongest in the mature stage. Once the warm core begins to weaken and disappear, it means that tropical cyclones will be denatured or filled. (2) Because the air around the eye of the typhoon rotates quickly, with high speed and strong centrifugal force, it is not easy for the air to enter the eye of the typhoon, so it cannot produce a wide range of rainy days, so the eye of the typhoon is clear.
I hope you can help me.
