Which country named the typhoon fireworks?

Typhoon fireworks are named after China. Typhoon Fireworks was upgraded to a tropical storm by the Central Meteorological Observatory at 2:00 on July 18, 2021, and was upgraded to a severe typhoon by the Central Meteorological Observatory at 11:00 on July 21. It was along the coast of Putuo District, Zhoushan City, Zhejiang Province around 12:30 on July 25. It made landfall. The maximum wind force near the center was level 13 (38 meters/second) at the time of landfall. It made landfall again on the coast of Pinghu, Jiaxing, Zhejiang Province around 9:50 on July 26.

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

Typhoon is a type of tropical cyclone. A tropical cyclone is a low-pressure vortex that occurs on the tropical or subtropical ocean. It is a powerful and deep tropical weather system. Our country divides tropical cyclones in the South China Sea and the northwest Pacific into six levels based on the maximum average wind force (wind speed) near the bottom center. Those with wind speeds of level 12 or above near the center are collectively called typhoons.
