the typhoon structure

Typhoon structure, from the center to the outside, is: typhoon eye area, cloud wall area, spiral rain belt area. Typhoon is a deep low-pressure system, and its central air pressure is very low. There is an air flow converging towards the center at the lower level, and the air flow at the upper level mainly diverges outward. If you cut the typhoon horizontally, you can see three obvious areas.

Typhoon Eye Area: It is very strange that the wind here is very small, with an average diameter of 40 kilometers. Sailors in it humorously call it the eye of the typhoon? Xanadu

Cloud wall area: a cloud wall area with a width of tens of kilometers and a height of more than ten kilometers around the typhoon eye. The cloud wall is towering here, the wind is howling, the rain is pouring, the sea is churning, and the weather is the worst.

Spiral rain belt area: spiral rain belt is outside the cloud wall, and several rain (clouds) belts gather spirally around the eye wall, and there will be showers and windy weather where the rain belt passes.
