What is the concept of six-level wind?

The concept of level 6 wind force is strong wind.

Grade 6 wind is called strong wind, and the wind speed is 10.8 ~ 13.8 m/s, which is equivalent to 39-49 km/h. Wind refers to the strength of wind blowing on objects. Generally speaking, according to various phenomena caused by wind blowing on objects on the ground or water surface, the magnitude of wind power is divided into 18, with the smallest being 0 and the largest being 17.

Wind speed is the forward speed of the wind. The greater the air pressure difference between two adjacent places, the faster the air flow, the greater the wind speed and the greater the wind force. Therefore, the magnitude of wind is usually expressed by wind power. The unit of wind speed is meters per second or kilometers per hour. When the weather forecast is released, the wind level is mostly used.

Wind power definition:

In 200 1 year, the China Meteorological Bureau issued the Regulations on Typhoon Operation and Service, which added typhoons above 12 to 17 and adopted Beaufort scale. /typhoon kloc-0/2, set at 32.4-36.9 m/s; The grade 13 is 37.0-41.4m/s.

14 is 4 1.5-46. 1 m/s, 15 is 46.2-50.9 m/s, 16 is 51.0-56. Typhoon Qionghai 30 years ago, the maximum wind force near the center was 73m/s, which exceeded the highest standard of 17. It is called 17 or above, and it is also a general statement about super typhoon in the international maritime community.
