What is the weather symbol of Yang Sha?

The weather symbol of sand blowing is "S" with "→" in the middle.

Sand blowing is because the wind blows up dust or sand on the exposed ground. The visibility of this weather is between 1 km and1km, which is called sand blowing weather. The difference between sand-blowing weather and dusty weather is that some dust is generated in situ and some is blown from other places.

The dust suspended in the atmosphere causes the horizontal visibility of the atmosphere to be less than 10 km. Dust storms and strong winds blow up the dust on the ground, making the air very turbid, and the horizontal visibility is less than 1 km. When the horizontal visibility is less than 500 meters, it is a strong sandstorm.
