How are the grades of wind power generation divided?

The total wind power level can be divided into 18.

Wind grade and symbol name wind speed land image sea surface wave height

Level 0 is called no wind 0.0-0.2 m/s, and the smoke is quiet 0.0 m.

1 is called soft wind 0.3- 1.5 m/s, and the smoke shows that there is no water drop at the peak of microwave in the wind direction 0.1m.

Level 2 is called Xiaofeng 1.6-3.3 m/s, and the small peak of the wind is not broken at 0.2 m.

Level 3 is called breeze 3.4-5.4 m/s, and the wave peak breaks 0.6 m.

Level 4 is called breeze 5.5-7.9 m/s, blowing dust, small waves and foam peak1.0 m.

The 5-level strong wind is 8.0- 10.7 m/s, and the wave breaking foam peak group is 2.0 m in the swing of young trees.

Level 6 is called strong wind 10.8- 13.8 m/s, and the wires have great waves and water drops of 3.0 m.

Grade 7 is called gale13.9-17.1m/s, and it is difficult to walk.

Grade 8 is called gale 17.2-20.7m/s, and the height of branch-destroying wave is 5.5m m.

Grade 9 is called gale, 20.8-24.4m/s, and the small damaged house rolls back 7.0m after the peak. ..

10 is called gale. Trees are pulled up at a speed of 24.5-28.4m/s, and the waves roll and roar up to 9.0m m. ..

1 1 is called a storm, with damage of 28.5-32.6 m/s, and the peak value is usually in water droplets,11.5 m.

The magnitude of 12 is called hurricane 32.7-36.9 m/s, which destroys huge waves and reaches14.0 m.

13 is called typhoon-37.0-41.4m/s.

14 is called strong typhoon -4 1.5-46. 1 m/s.

15 is called a strong typhoon -46.2-50.9 m/s.

16 became a super typhoon -5 1.0-56.0 m/s.

17-56.1-61.2m/s

How many winds are there? What are their names?

The wind power level is divided into 18, which are called no wind, breeze, small wind, breeze, strong wind, gale, gale, storm, typhoon, strong typhoon and super typhoon.

1 and 0 wind is also called no wind.

2, 2 The wind is called breeze, the leaves are slightly noisy, and people's faces feel windy.

3 or 4 winds are called breezes, and the twigs of trees shake, which can blow up dust and paper on the ground.

4 or 6 winds are called strong winds, branches are shaking, wires are whistling, and it is difficult to walk with an umbrella.

5 or 8 winds are called strong winds, the twigs of trees can be broken, and people walk against the wind with great resistance.

6, 10 wind is called gale, which is rare on land. Trees can be pulled up and buildings are seriously damaged.

7. Winds above12 are called typhoons or hurricanes, which are extremely destructive and rarely seen on land.

How are the grades of wind classified?

Wind power refers to the strength of the wind blowing on an object. 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.

The magnitude of wind speed is often expressed by several winds. The level of wind is determined according to the degree of influence of wind on ground objects. In meteorology, generally according to the size of the wind is divided into twelve levels:

Level 0 wind is also called no wind.

Level 2 wind is called breeze, the leaves are slightly noisy, and people feel windy.

Level 4 wind is called breeze, and the twigs of trees shake, which can blow up dust and paper on the ground.

The 6-level wind is called strong wind, the branches are shaking, the wires are whistling, and it is difficult to walk with an umbrella.

The 8-level wind is called strong wind, the twigs of trees can be broken, and people walk against the wind with great resistance.

10 wind is called gale, which is rare on land. Trees can be pulled up and buildings are seriously damaged.

Winds above 12 are called typhoons or hurricanes, which are extremely destructive and rarely seen on land.

In the weather forecast, we often hear the expression "the north wind is 4 to 5", in which the wind refers to the average wind; If you hear the expression "gust 7", gust refers to the wind with high and low wind speed, and the wind at this time refers to the maximum wind force.

How is the wind graded?

Level 0 wind is also called no wind.

The 6-level wind is called strong wind, the branches are shaking, the wires are whistling, and it is difficult to walk with an umbrella.

The 8-level wind is called strong wind, the twigs of trees can be broken, and people walk against the wind with great resistance.

10 wind is called gale, which is rare on land. Trees can be pulled up and buildings are seriously damaged.

Winds above 12 are called typhoons or hurricanes, which are extremely destructive and rarely seen on land.

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; 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.
