What grades do people divide the wind into, and how are they stipulated?

According to the national standard Wind Power Generation Grade issued in June 20 12, the wind power is divided into 18 grades.

The lowest level is 0 and the highest level is 17.

Usually, the magnitude of wind power is expressed by wind power. The unit of wind speed is meters per second or kilometers per hour. When releasing the weather forecast, most of them use the wind level.

China Meteorological Bureau issued Typhoon Business and Service Regulation 200 1:

Typhoons above 12 plus Beaufort wind force grade of 17.

12 typhoon is set to 32.4-36.9 m/s.

The grade 13 is 37.0-41.4m/s.

The grade 14 is 4 1.5-46. 1 m/s.

The super-strong wind exceeding 17 is called 18, which is the common name of super-large typhoon in the international maritime community.
