What is a typhoon of 12?

The wind level is Song (12), and there is no wind on the ground: that is, the wind force is zero. This scene is hard to see. There are waves on the water, and "waves" are not "sparkling". 12 wind, also known as hurricane, is rare on land and has great destructive power. Share some catchy wind songs (12 level).

Song of the Wind (12) 1 version 1

Ji Feng Song

There is no wind and smoke on the ground;

First-class light smoke deviates with the wind;

The second breeze leaves are ringing;

The third branch shakes the red flag;

Level 4 dust dances on the ground;

Five-level water surface waves;

It is difficult to hold up an umbrella with a 6-level wind;

Seven-level trees are difficult to shake and walk;

Eight winds blow off branches;

Nine-level roof flying tiles;

Ten-level wind energy uproots trees;

Eleven, twelve, the land is sparse.

Version 2

Ji Feng Song

Zero-order smoke column goes straight into the sky;

First-class light smoke deviates with the wind;

The second breeze blows the face;

Three-level moving leaf red flag exhibition;

Four-stage branch flying paper;

Five-level small trees with leaves shake;

Level 6 is difficult to walk with an umbrella;

It is inconvenient to walk in the wind in the seventh grade;

Eight winds blow off branches;

Nine-level roof flying tiles;

Ten-level uprooting trees and toppling houses;

1 1 layer1layer 2 See you at sea.

Analysis: Zero-order smoke column goes straight into the sky: when there is no wind, smoke is like a pillar that goes straight into the sky, not to say that the smoke column is zero-order. Secondary wind blowing on the face: blowing on the face and body, the wind that people can feel is at least secondary wind. This wind song and the first wind song complement each other.

Version 3

Ji Feng Song

Zero wind, straight smoke;

The first grade wind, the smoke is slightly biased;

Secondary wind, leaves ring;

The third wind, the flag fluttering;

Four winds, dust;

Five winds and waves;

Six winds, big trees shake;

Seven winds, difficult to go;

Eight winds, broken branches;

Nine winds, the chimney collapsed;

Ten winds, uprooted;

Xi. Scarcity of land;

Twelfth grade, less;

The wind roared and the waves were huge.

Analysis: this wind-level song is like a tongue twister, and it is the easiest to recite. From the compulsory education curriculum standard experimental textbook "Chinese Grade Six Volume I" Exercise 5, 104.

Version 4

Ji Feng Song

Zero-order smoke column goes straight into the sky;

The first-class smoke was blown by the wind;

The second breeze blows the face;

Three-level moving leaf red flag exhibition;

Four-stage branch flying paper;

Five-level small trees bend with the wind;

Level 6 is difficult to carry an umbrella;

It is inconvenient to walk in the wind in the seventh grade;

Eight winds break branches;

Nine-level roof flying tiles;

Ten-level uprooting trees and toppling houses;

It is rare to see 1 12.

Analysis: this poem has consistent rhyme, is catchy to read and easy to recite.

Extended data

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 releasing the weather forecast, most of them use the wind level. How to determine the series of wind power?

The distance that the wind moves per second-the wind speed, its formula is "from all the way to nine, multiplied by two". It means: from 1 to 9 winds, multiply each level by 2, and you can roughly get the maximum wind speed.

For example, the maximum speed of the first wind is 2 meters per second, the second wind is 4 meters per second, the third wind is 6 meters per second, and so on. There are also transitional figures between different levels of wind, such as 1-2 meters per second for the first level wind, 2-4 meters per second for the second level wind, 4-6 meters per second for the third level wind and so on.

According to the need, wind power can also be converted into corresponding wind speed, that is, the distance that air flows in unit time, in meters per second. The conversion formula is for reference: two to one is one, and three levels plus one.

Grades four to nine are not difficult to calculate, and the series is reduced by two times three. Ten to twelve are rare, so ten is easy to remember. Ten-level wind speed is twenty-seven, with one more level every four levels. That is, the wind speed of the primary wind is equal to 1 m/s, the wind speed of the secondary wind is equal to 2 m/s, and the wind level of the tertiary wind plus 1 is equal to 4 m/s.

Subtract 2 from the sequence from 4 to 9 and multiply it by 3 to get the corresponding wind speed. The wind speed algorithm from 10 to 12 is the same. The wind speed of 10 is 27m/s, and then the wind speed of 1 1 is 3 1m/s by adding 4, and the wind speed of 12 is 35m/s. ..
