What does a Category 12 typhoon look like?
Wind Level Song (Level 12)
Wind Level Song (Level 12), there is no wind on the ground: that is, zero level wind. This scene is very difficult to see, and the water surface has waves. "Waves" are not "sparkling". Category 12 winds are also called hurricanes, which are rarely seen on land and are extremely destructive. Share some catchy wind-level songs (level 12). Wind-level songs (level 12) 1
Version 1
Wind Level Song
There is no wind and smoke goes straight up from the ground;
First-level light smoke drifts with the wind;
p>
Level 2 leaves are rustling in the breeze;
Level 3 branches are waving red flags;
Level 4 dust is dancing on the ground;
Level 5 water surface is rippled;
Level 6 strong winds make it difficult to lift an umbrella;
Level 7 winds shake the trees and make walking difficult;
Level 8 winds break branches;
Nine Level 10 roofs with flying tiles;
Level 10 strong winds can uproot trees;
Level 11 and 12 are rare on land
Version 2
Wind level song
Level zero smoke column reaches the sky;
Level one light smoke drifts with the wind;
Level two light breeze blows on the face;
Level 3 leaf moving red flag display;
Level 4 branch shaking flying paper;
Level 5 leafy tree shaking;
Level 6 walking with umbrella Difficult;
It is inconvenient to walk in the wind at level 7;
Branches are broken by winds at level 8;
Tiles fly off the roof at level 9;
Level 10: uprooting trees and houses;
Level 11: Seen at sea
Analysis: Level 0 smoke pillar reaches the sky: the smoke when there is no wind is like a pillar reaching the sky, but it is not. The smoke column is level 0. The second level breeze blows on the face: the wind that people can feel is at least level 2 wind. This wind level song complements the first wind level song. Function.
Version Three
Wind Level Song
Zero level wind, smoke rising straight up;
One Level 2 wind, the smoke is slightly away;
Level 2 wind, the leaves are rustling;
Level 3 wind, flags fluttering;
Level 4 wind, dust is rising; < /p>
Level 5 winds cause waves;
Level 6 winds shake the trees;
Level 7 winds make traveling difficult;
Eight Level 10 winds, branches are broken;
Level 9 winds, chimneys collapse;
Level 10 winds, tree roots are uprooted;
Level 11 winds, land rare; < /p>
Level 12 is rare;
The wind roars and the waves surge into the sky.
Analysis: This wind-level song is like a tongue twister and is the easiest to memorize. From Exercise 5 of "Compulsory Education Curriculum Standard Experimental Textbook Chinese Language for Sixth Grade (Volume 1)", on page 104.
Version 4
Wind Level Song
The zero-level smoke column soars into the sky;
The first-level blue smoke drifts with the wind;
Level 2 light breeze blows the face;
Level 3 leaves moving red flags;
Level 4 branches shaking pieces of paper;
Level 5 small The tree bends with the wind;
It is difficult to lift an umbrella at level 6;
It is inconvenient to walk against the wind at level 7;
The branches are broken by wind at level 8;
Level 9 roof tiles flying;
Level 10 uprooting trees and houses;
Level 11 and level 11 are rare on land.
Analysis: This poem has the same rhyme and ending, making it catchy and easy to recite. Wind Level Song (Level 12) 2

Level 6 has difficulty in lifting an umbrella; level 7 has difficulty walking in the wind; level 8 causes branches to break due to wind; level 9 causes roof tiles to fly; level 10 uproots trees and houses; levels 11 and 2 are rare.
Extended information
Wind speed is the forward speed of the wind. The greater the air pressure difference between two adjacent places, the faster the air flows, the greater the wind speed, and the greater the power of the wind. Therefore, wind force is usually used to express the size of the wind. The unit of wind speed is expressed in meters per second or kilometers per hour. When issuing weather forecasts, wind levels are mostly used. How is the wind force level determined?
The distance the wind moves per second - wind speed, the formula is "from all the way to nine, times 2 for each level". This means: from level one to level nine, multiply each level by 2 to roughly get the maximum speed of the wind.
For example, the maximum speed of level 1 wind is 2 meters per second, level 2 wind is 4 meters per second, level 3 wind is 6 meters per second... and so on. There are also transition numbers between various levels of wind. For example, level 1 wind is 1-2 meters per second, level 2 wind is 2-4 meters per second, level 3 wind is 4-6 meters per second, and so on.
If needed, the wind force can also be converted into the corresponding wind speed, which is the distance of air flow per unit time, expressed in meters per second. The conversion formula is for reference: two is two to one is one, Level three plus one on top of three.
It is not difficult to calculate levels four to nine. Just subtract two and multiply the number by three. Levels ten to twelve are rare, so just keep level ten in mind and it will be easy to handle. Level 10 wind speed is 27, add four for each additional level. That is: the wind speed of Level 1 wind is equal to 1 meter/second, and the wind speed of Level 2 wind is equal to 2 meters/second. The wind level of Category 3 wind is increased by 1, and its wind speed is equal to 4 meters/second.
For levels four to nine, subtract 2 and multiply by 3 from the series to get the wind speed of the corresponding level. The wind speed calculation for level 10 to level 12 is the same. The wind speed of level 10 is 27 meters/second. Add 4 to this to get the wind speed of level 11 of 31 meters/second. Add 4 to get the wind speed of level 12 of 35 meters/second.
