How to write the symbol of wind power?

Wind direction and grade in weather symbols: represented by wind vector, composed of wind stalk and wind plume.

wind direction stalk: indicates the direction of wind, with 8 directions.

wind feather: 3 or 4 short strokes and triangles indicate strong winds, which are vertical to the right of the end of the wind pole (northern hemisphere).

Level 1-2: Level 1 vertical bar 1 horizontal

Level 3-4: Level 1 vertical bar 2 horizontal

Level 5-6: Level 1 vertical bar 3 horizontal

Level 7-8: Level 1 vertical bar 4 horizontal

Level 8 or above: Level 1 vertical bar 1 triangle looks like a small flag

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 strength of the wind. Therefore, the size of the wind is usually expressed by the wind force. The unit of wind speed is expressed in meters per second or kilometers per hour. When releasing the weather forecast, most of them use the wind level.

Calculation of wind speed:

The distance that the wind moves per second is the wind speed, and its formula is "from all the way to nine, multiplied by two". It means: from level 1 to level 9 wind, multiply each level by 2, and the maximum speed of the wind can be roughly obtained. For example, the maximum speed of the first-class wind is 2m per second, the second-class wind is 4m per second, and the third-class wind is 6m per second, and so on.

there are transitional figures between different levels of wind, such as the first level wind is 1-2 meters per second, the second level wind is 2-4 meters per second, the third level wind is 4-6 meters per second, and so on. According to the need, the wind power can also be converted into the corresponding wind speed, that is, the distance of air flow per unit time, expressed in meters per second.

that is, the wind speed of the primary wind is equal to 1m/s, and that of the secondary wind is equal to 2m/s.. Add 1 to the wind level of the third-class wind, and its wind speed is equal to 4 meters per second. Subtract 2 from series 4 to 9 and multiply 3 to get the corresponding wind speed. The wind speed algorithm for grades 1 to 12 is the same. The wind speed for grade 1 is 27m/s, on this basis, add 4 to get the wind speed for grade 11 of 31m/s, and add 4 to get the wind speed for grade 12 of 35m/s..

the wind is represented by the wind vector, and consists of wind direction stalks and wind plumes.

wind direction stalk: indicates the direction of wind, with 8 directions.

wind feather: 3 or 4 short strokes and triangles indicate strong winds, which are vertical to the right of the end of the wind pole (northern hemisphere).

Tornado: It is a visible wind, but it brings great disaster to the ground.
