What is the weather symbol of the wind?

Wind direction symbols are generally represented by wind columns with tail feathers, in which the tail feathers of wind symbols above grade 8 are pennants.

Symbol: It consists of wind stems and wind feathers.

Wind handle: indicates the direction of the wind, with 8 directions.

Wind feather: 3 or 4 short strokes and triangles indicate strong wind, perpendicular to the right side of the wind pole (northern hemisphere).

1- secondary: 1 vertical line 1 horizontal line

Grade 3-4: 1 vertical bar and 2 horizontal bars

Layer 5-6: 1 vertical line 3 horizontal line

Grade 7-8: 1 vertical bar 4 horizontal bar.

Above level 8: 1 vertical bar 1 triangle is like a small flag.

Extended data:

Wind is caused by air pressure difference. When the air pressure difference exists, the air will move from the high pressure area to the low pressure area, thus producing winds with different wind speeds. On a rotating planet outside the equator, the airflow will be deflected by Coriolis force.

On a global scale, the two main driving factors of large-scale wind (atmospheric circulation) are the difference in heating between the equator and the polar regions (the difference in absorbing solar energy leads to buoyancy) and the rotation of the planet.

In high altitude areas outside the equator, which are not affected by ground friction, large-scale winds often reach geostrophic balance. On the surface of the earth, friction will gradually slow down the wind. Surface friction will also cause more wind to blow to the low pressure area.
