The structure of typhoon fireworks is symmetrical, the cloud system is thick and thick, and the typhoon eye is obvious. At the same time, the low-level inflow and high-level outflow conditions are good, which is conducive to the development and enhancement of typhoons. Multiple typhoons interact with each other and have complicated paths. The typhoon is large and has a wide range of influence. After landing, it lasted for a long time on land and accumulated heavy rainfall.

Typhoon is a kind of tropical cyclone. Tropical cyclone is a low-pressure vortex that occurs on the surface of tropical or subtropical ocean, and it is a powerful and profound tropical weather system. In China, tropical cyclones in the South China Sea and the Northwest Pacific are classified into six grades according to the maximum average wind speed near the bottom center, and the wind near the center reaches 12 or above, which is collectively called typhoon.
